what is Malware,spyware,trojan and worms in computer?

2012-12-06T08:58:00.002-08:00

What is Malware?

The word Malware is short for malicious software, and is a general term used to describe all of the viruses, worms, spyware, and pretty much anything that is specifically designed to cause harm to your PC or steal your information.

Viruses Wreak Havoc On Your Files

The term computer virus is often used interchangeably with malware, though the two don’t actually have the same meaning. In the strictest sense, a virus is a program that copies itself and infects a PC, spreading from one file to another, and then from one PC to another when the files are copied or shared.

Most viruses attach themselves to executable files, but some can target a master boot record, autorun scripts, MS Office macros, or even in some cases, arbitrary files. Many of these viruses, like CIH, are designed to render your PC completely inoperable, while others simply delete or corrupt your files—the general point is that a virus is designed to cause havoc and break stuff.

You can protect yourself from viruses by making certain your antivirus application is always updated with the latest definitions and avoiding suspicious looking files coming through email or otherwise. Pay special attention to the filename—if the file is supposed to be an mp3, and the name ends in .mp3.exe, you’re dealing with a virus.

Spyware Steals Your Information

Spyware is any software installed on your PC that collects your information without your knowledge, and sends that information back to the creator so they can use your personal information in some nefarious way. This could include keylogging to learn your passwords, watching your searching habits, changing out your browser home and search pages, adding obnoxious browser toolbars, or just stealing your passwords and credit card numbers.

Since spyware is primarily meant to make money at your expense, it doesn’t usually kill your PC—in fact, many people have spyware running without even realizing it, but generally those that have one spyware application installed also have a dozen more. Once you’ve got that many pieces of software spying on you, your PC is going to become slow.

What many people don’t realize about spyware is that not every antivirus software is designed to catch spyware. You should check with the vendor to make sure the application you are using to protect you from malware is actually checking for spyware as well. If you come across a PC that is already heavily infected, run a combination of MalwareBytes and SuperAntiSpyware to clean it thoroughly.

Scareware Holds Your PC for Ransom

Scareware is a relatively new type of attack, where a user is tricked into downloading what appears to be an antivirus application, which then proceeds to tell you that your PC is infected with hundreds of viruses, and can only be cleaned if you pay for a full license. Of course, these scareware applications are nothing more than malware that hold your PC hostage until you pay the ransom—in most cases, you can’t uninstall them or even use the PC.

If you manage to come across a PC infected with one of these, your best bet is to Google the name of the virus and find specific instructions on how to remove it, but the steps are usually the same—run a combination of MalwareBytes, SuperAntiSpyware, and maybe ComboFix if you need to.

For more on scareware, including a full walk-through of how a PC actually gets infected in the first place, check out the guide I wrote on removing Internet Security 2010 and other fake antivirus malware.

Trojan Horses Install a Backdoor

Trojan horses are applications that look like they are doing something innocuous, but secretly have malicious code that does something else. In many cases, trojans will create a backdoor that allows your PC to be remotely controlled, either directly or as part of a botnet—a network of computers also infected with a trojan or other malicious software. The major difference between a virus and a trojan is that trojans don’t replicate themselves—they must be installed by an unwitting user.

Once your PC has been infected with the trojan, it can be used for any number of nefarious purposes, like a denial of service (DoS) attack against a web site, a proxy server for concealing attacks, or even worse—for sending out buckets of spam. Protection against trojans works the same way as viruses—make sure that your antivirus application is up to date, don’t open suspicious attachments, and think long and hard before you try and use a downloaded crack for Photoshop—that’s one of malware authors’ favorite spots to hide a trojan.

Worms Infect Through the Network

Computer worms use the network to send copies of themselves to other PCs, usually utilizing a security hole to travel from one host to the next, often automatically without user intervention. Because they can spread so rapidly across a network, infecting every PC in their path, they tend to be the most well-known type of malware, although many users still mistakenly refer to them as viruses. Image by me and the sysop.

Some of the most famous worms include the ILOVEYOU worm, transmitted as an email attachment, which cost businesses upwards of 5.5 billion dollars in damage. The Code Red worm defaced 359,000 web sites, SQL Slammer slowed down the entire internet for a brief period of time, and the Blaster worm would force your PC to reboot repeatedly.

Because worms often exploit a network vulnerability, they are the one type of malware that can be partially prevented by making sure your firewall is enabled and locked down.

How secure is your ADSL connection ?

2012-06-04T10:03:00.001-07:00

Now a day most of us are using ADSL due to it's low cost , but is this connection is secure ?
Let see how secure is our ADSL connection for that you need ip Scan program , there are many ip scan program on net ,let down one from net

step 1: go to Google and search for a program called angry ip scanner

step 2: click on the first link and download the program and insert that program

step 3: find out your pubic ip by going to site called www.whatsmyip.net copy that ip and past that ip on the ip range of program and change the last digit of ip range to 1 and to range last digit to 255

step 4: then click on start

it will display all the list of router that are connected to net at that time.

step 5: right click on any ip list and go to open then web browser it will display router setting page and it will ask you for username and password since most of people do not change their router password so username must be admin and password must be admin or 123 or password.

step 6: now you are at user router setting page from which you can get all the information and access user computer and even change the setting of router.

so when you are using ADSL connection think once that is your connection is secure or nor .

How to secure your facebook account

2012-01-10T05:59:00.000-08:00

Facebook is one of the most commonly used social networking site and also the one of the most unsecured site now a day. Every month thousand of Facebook user information , photos log in information leak including the founder and CEO of Facebook Mark Zuckerberg. It have proved that Facebook is one of the most unsecured site but we can try to make it little more secure by following simple step which are provided by Facebook and your browser.
Here are some step that can help you to be little more secure but not 100% secure because in the world of open network NO ONE IS SECURE 100%.

STEP 1:
Before making you socal networking secure first you have to secure you network , for that use good anti virus ,do regular update of your anti virus.never use free or open wifi or internet , there will be chance that other person is viewing your conversation .

STEP 2:
Never save your user name and password while using net from cyber or from unsecured network.

STEP 3:

Use secure browing option while using net from cyber or unsecure place ,which will delete all your information after closing the browser , for that you can use Enter Private browsing on Firefox by right click it or New incognito window on Google chrome or use Start InPrivate Browsing on IE.
STEP 4:

Click on drop down menu next to Home tab and click on Privacy setting and click on Public tab if you want your information visible to all user or select friend if you want your information visible to your friend only or you can set your own setting by selecting Custom.

Next is again got o drop down menu next to Home tab click on Account setting then security setting .

There you will see different tab first one is Secure browsing click on enable which will enable https which is more secure than http , http use port number 80 for data transfer which can easily capture by middle person or unwanted people and decode the data and know all your data send from it where as https use port number 443 which is more secure than http and it's data can't be decode till now .(port number are special address used to transfer different type of data on net ,it's like road address for different data on network)

another is Login notifications :for this you have to provide your mobile number ,i found it more helpful because when able anyone log into your account it will send text message to your mobile.

next is Log in Approvals: from my view it is most secure way of facebook security because even if anyone know your password ,they also have to enter security code also which is send to your mobile so to log into your account that have to get access of your mobile also .

App password : it is for your application security

Recognized Devices : it show the list of device from which you have log into your account.

Active Sessions : it show the list of place from where you have log into your account.

MAPPING ISDN MODEL TO OSI

2012-01-01T22:30:00.001-08:00

In ISDN network, only data link layer and physical layer of the OSI model is consider. It was intended to provide right to use to voice and data services at the same time. It operates on 2 channel they are ISDN D and ISDN B channel. 3 layer is supported by ISDN D channel, which is used to switches the ISDN calls.

They are:

Synchronization of physical layer

Layer 2 handshakes and setup of data

Layer 3 progress of the signal

Layer 1 it provides the connection between two node.

Layer 2 it is used to manage the ISDN station and handshakes network of two TEI (terminal equipment identifier). It is given by the network and Particular be ISDN terminal which are connected to layer 2.

The network determination be the UA response (users recognize). The ISDN station and network handshake DURING continue to ISDN calls, It consists of the layer 3 is a communication and a part of information. Element of communication data is attached to which are used to observed the progress of a request. Different requirement includes on Layer 3 link. The designer of ISDN is skilful of wide variety of hosted to finale user request.

ISDN SERVICES PROVIDED BY SERVICE

ISDN main objective is to deliver help to end users through a full 7-layer OSI model.

Mostly ISDN service is distributed into two services:

Bell

TV facilities (teletext, fax 4, telephony, cinematic writing, telex)

Bell

This facility is used to allocation user records and control signal in the middle of two devices. Service holder has the sort of 300 bps to 10 + Gbps. It is in the elementary categories of (i) the information transmission characteristics, including the level of data transmission, the direction of records flow and rate of data allocation. Access Method (ii) parts of the structure affected by a porter. Certain categories are accessible via the telephone structure which contains synchronous and asynchronous facts. This service is too responsible for given the support to the junior level of three standard of seven layers.

Diagram exemplifying decide to direct customer records to a PC is connected to a civic telephone network. The service maintenance is 9.6 kbps, Circuit Switched Data’s . The system dials the telephone structure via the modem and the transfer to the modem calls to accept the requests that the sender sends data openly to the modem line station. The end to end broadcast is adjusted near 9.6 kbps.

TV services

TV service supplier using message terminals, the net function and the utility provided by dedicated centers. It is maintained by an ISDN. More than one of the optional carrying capacity should remain rated for a reason TV facilities. Under the duty of the service TV, network interworking purpose may be required. A user running a particular application is not consuming anti-Tele service with the carrying capacity.

Tele is accountable for providing care through service-7 layers of the OSI model and production use of a generally low volume for high-level support facilities.

The following were recognized TV services to be maintained so far using ISDN.

Telephony

It delivers downtime of 2-way speech chat via the net.

Services provided by the ppp protocol

2012-01-01T22:29:00.002-08:00

Point to point protocol is used in many technology, like dial up connection and digital subscriber lines technology. Describe of following services is given below:

DIAL UP LINES

It is a temporary connection to communication among one or more telephones line. In dial up line to transmit data is similar as of using a telephone to make a call. A modem is added at the two ends of sender and receiver. A connection is established between two ends when receiver answers the call and the data is transmitted. When the transmission is completed, the modem at either end terminates the connection by hanging up.

Dial up line makes a connection between to location by using PSTN and modem.

This method of point to point connection depends up on the operating systems that are running.

DIGITAL SUBSCRIBER LINES

In digital subscriber line is used by mobile user or small business organization by using digital line for transferring data. It delivers large size of data on standard cable by using broadband connection. Packet header of ppp protocol

Mapping ppp protocol stack to OSI Reference Model

2012-01-01T22:29:00.000-08:00

Example of sending an email using ppp protocol.

Layer 7: We use an email client program like Outlook Express, which has SMTP and POP3 functions according to application layer of OSI (Layer 7)

Layer 6: We send an email, formatted in ASCII or HTML. The application then creates a data unit formatted in ASCII or HTML according to Presentation layer of OSI.

Layer 5: An email message uses the operating system to open a session for inter-host communication according to session layer of OSI

Layer 4: A TCP socket with the SMTP port number 25 server is opened by the operating system. A virtual circuit is opened between your computer using point to point (ppp) connection and the email server used TCP according to transport layer of OSI .

Layer 3: Our computer searches for the IP address of the SMTP server according to the routing table of the operating system. If it is not found in the routing table, it will forward it to the company router for path determination. The IP protocol is at network layer of OSI

Layer 2: In data link layer of OSI the IP packet is transformed to an Ethernet frame.

Layer 1: The Ethernet frame is converted to electrical signals that are transmitted through the 5 cable according to physical layer of OSI

Ppp(point to point protocal)

2012-01-01T22:28:00.000-08:00

In PPP or point-to-point protocol the two components are connected directly, there is no any interference from any other components. It is data link protocol which is used to establish direct connection between two nodes of network. It have the property of authentication to the network, transmission on this protocol is encrypted and compressed.

Ppp is used on different types of physical network likes serial cable, cellular phone, phone line, trunk line, fiber such as SONET and in broadband connection. Since modem line can’t transmit IP packets on their own so ppp is used for dial- up access to the internet by the ISP. the most commonly ppp protocol used by the ISP are point-to point protocol over Ethernet(ppoE) and point-to point protocol over ATM(ppoA) for establish Digital Subscriber line (DSL).

OSI stand for Open System Interconnection., which was developed by ISO (International Standards Organization) in 1977. It is the most widely accepted model for

understanding the network communication.

Introduction to the Computer Communication Architecture

2012-01-01T22:19:00.000-08:00

What is a computer network?
Here you will learn about computer network architecture, physical design, logical topology, protocols, implementation, communication planning and basic communication techniques.In order to properly build, maintain and secure a network, you should first know what is a compute network and how the data travels through the wired or wireless network. To say a person with a good networking skills in a position that a network consisting of a computer, cable, PRI lines, routers, switches, network cards, telephone systems, TIS, fiber optic and Ethernet cables. A person who has a strong background in the data network must know that a network consists of a server, workstations, routers, hubs, WAN, LAN, fiber optic and Ethernet cables and devices. Both the telecommunications and data communications people agree that the wiring is an essential component of any computer network.
The simplest definition of the data network is to connect two computers together more computers to share data and resources. The network is available in different sizes and shapes, from home networks to wide area networks. Despite the different roles and different sizes of a network, you can design some general similarities in all networks, such as protocols, architecture and topology /.
Computer Network Architectures
Basically, computer network design (local area network) in three basic types such as LAN, MAN (Metropolitan Area Network) and WAN (Wide Area Network Division. A LAN can consist of two or more computers in the same room or building. Fiber or Ethernet cables are used to connect the computers in a LAN. home networks, office and personal networks are networks in LAN. A typical MAN consists of two or more computers at two different locations in the same city.
A man can be wired (fiber optic) or wireless, and a number of communication devices are used in a MAN. A WAN consists of two or more computers in two different geographical areas (different cities or countries) and there are several ways to turn the computer on a WAN such a connection as a leased line (ISDN lines, radio waves, microwaves, dial-up connections and connectivity through Satellite. The Internet is a WAN largest in the world. With the invention of wireless networks, mobile and optical technology, the use of the lines has been reduced. There are a number of conditions that describe the architecture of a network.
Computer Network Topologies
The topology or physical design is closely related to the architecture of a network.Topology defines how the network is physically connected. There are three main types of the topologies.• Star topology: In a star topology, all network components to the central office which is connected to a hub or switch. The star topology is mainly in use in the LAN.• Bus topology: In the bus topology of the network-connected components is the same cable. This is also called line or backbone.• Ring topology: In the ring topology, all components are connected together in the form of a ring. A token continuously through the loop.
Network Architecture Terminology
• CAN (Campus Area Network): CAN is a kind of a network that connects the building / office of a university, educational or office complex.• Intranet: Intranet is a private network belonging to an office, school or organization, and that is only accessible to authorized users.• Internet: The Internet is a network of networks connecting millions and charged each other of different designs.• MAN (Metropolitan Area Network) MAN is a kind of a network that is designed for a city.A MAN is larger than LAN but smaller than WANs.• SAN (Storage Area Network): a type of SAN is a network that can be used to connect the storage devices connected to RAID, file servers and tape systems.• VLAN (Virtual Local Area Network): VLAN is a kind of a network to communicate with the computer on separate physical networks as if they were connected to the same network allows.• Client-Server: Client-server is a type of networking, which is called dedicated systems, services, and the system that these services are called to preserve jobs. The main services include file, printer, scanner, CD, hard disk, processor, Internet connection and other services.• Peer-to-peer: This is a type of a network where each computer shares the same functionality. No central server is required in the peer-to-peer networks.
Computer network protocols and the OSI Model
Protocol is one of the most important components of a computer network. Protocol is a set of rules on the roads or a communication language understood by all computers and devices, agreed. A protocol defines error control how the data are sent and received, and transferring data between systems. There are a variety of protocols and the following is a list of the most commonly used protocol in the computer communications.• AppleTalk: AppleTalk is a communications protocol used by the system to Apple Macintosh computers, was developed to connect the printer.• Asynchronous Transfer Mode (ATM): ATM is a protocol type, in which data travels in the form of fixed size packets. The fixed rate packages offer a high speed, data security, video and voice communications over the same network.• DECnet: DECnet is a protocol that was developed by Digital Equipment system to connect the PDP and VAX systems.• Ethernet: Ethernet is a LAN protocol that was developed by Intel, Xerox, Digital Equipment and Systems. Ethernet is a most widely used LAN communication standard.• Fiber Distributed Data Interface (FDDI): FDDI is a protocol to transmit the data over the fiber optic cable.• Internet Protocol (IP): IP is a protocol for transferring data between the packet-switched IP networks, originally developed by the DOD (Department of Defense) was developed.TCP / IP (Transmission Control Protocol / Internet Protocol) is a suite of protocol and FTP, HTTP, e-mail, telnet, all IP protocols.• Internetwork Packet Exchange (IPX): IPX is a network protocol that is used by the Novell Netware operating systems.• NetWare: Netware is a LAN protocol developed by Novell Corporation.• Signaling System 7 (SS7): SS7 is a telecommunications protocol that was developed by the International Telecommunication Union is developing.• Systems Network Architecture (SNA) SNA is a set of protocols which was developed by the IBM mainframe systems developed.• Token Ring: Token Ring is a LAN protocol that was developed by IBM, in which systems have the token before they transfer the data. Transmission Control Protocol / Internet Protocol (TCP / IP): TCP / IP is a suite of protocols used to connect the computer on the Internet. TCP / IP is the most commonly used protocol.• X.25: X.25 is a protocol that was developed by the CCITT for packet-switched network.
Protocols are combined with the OSI model. OSI model is an ISO standard for the communication system. There are seven layers in the OSI model, and each layer performs the various functions. The seven layers are Application, Presentation, Session, Transport, Network, Data Link and Physical layers. Each layer know how to communicate with the upper and lower layer. You can change the names of all layers, to remember the following theorem.
"Everyone seems to need data processing"
Planning a Logical Network Design
If you plan a logical network design, you can either start from scratch or upgrade an existing network. You should provide sufficient information about the network components, hardware, protocols and topologies. You should analyze the traffic patterns, safety needs, future expansion and server capability, Internet access for its clients, FTP, and other things. You should also have a plan for disaster recovery, data recovery and instant troubleshooting techniques.

How to Make a Trojan Horse

2012-01-01T22:17:00.000-08:00

Most of you may be curious to know about a Trojan or Virus on your own. Here is an answer to your curiosity. In this post I will show you how to make a simple Trojan horse on your own with the C programming language. This Trojan, when they eat the hard disk is running on the root drive (the drive where Windows is installed, usually C: drive) of the computer on which it runs. Also this Trojan works pretty fast and is able to eat up about 1 GB of free hard disk space for every minute it is running. So I will call this as Space Eater Trojan. Because of this Trojan is written in a programming language, it is often not detected by antivirus engines. The source code for this Trojan can be downloaded at the end of this post. Let's see how this trojan ...Before going to the characteristics of this Trojan, you need to know what exactly is a Trojan and explain how it works. Since most of us think, a Trojan or a Trojan horse is not a virus.In simple words, a Trojan horse is a program to perform a desired function appears to be unknown but in fact performs malicious functions to allow unauthorized access to the host machine or damage the computer.Now you can move to the working class of our TrojanThe Trojan horse that I've done seems to be an anti-virus program that scans the computer and removes threats. But in reality it is doing nothing but fill the hard drive on the root drive by Simply fill it with a huge garbage file. The rate at which it fills the hard disk is too high.As a result of the disc gets up to 100% with this Trojan running in minutes filled. Once the memory is full, notify the Trojans, the scan is complete. The victim is not able to clean up hard drive space with any cleanup program. This is because the Trojan intelligently creates a huge file in the Windows \ System32 folder with the extension. Dll. As the junk-file has the. Dll extension, it is often ignored by the disk cleanup software. So for the victims, there is now to recover space on your hard disk, unless reformatting his drive.The algorithm of the trojan is as followsFirst Look for the root driveSecond Navigate to the root drive on WindowsSystem32Third Create the file named "spceshot.dll"4th Start dumping the garbage on the above file and will continue to grow, the size, full to the hard disk5th Once the drive is full, stops the process.
