WORM_STRATION.FA

It is another email virus that comes as an attachment. This worm propagates by attaching copies of itself to email messages that it sends to target addresses gathered from the Windows Address Book. It is capable of sending email messages without using mailing applications, such as Microsoft Outlook. Its main payloads are dropping and downloading malicious file.

Email Spoofing

E-mail spoofing is the forgery of an e-mail header so that the message appears to have originated from someone or somewhere other than the actual source. Distributors of spam often use spoofing in an attempt to get recipients to open, and possibly even respond to, their solicitations. Spoofing can be used legitimately. Classic examples of senders who might prefer to disguise the source of the e-mail include a sender reporting mistreatment by a spouse to a welfare agency or a "whistle-blower" who fears retaliation. However, spoofing anyone other than yourself is illegal in some jurisdictions.

Most Dangerous Threats

These are some of the most dangerous threats:
 

NIMDA:

Shortly after the September 11 tragedy this computer virus infected hundreds of thousands of computers worldwide. Nimda was considered to be one of the most complicated viruses, having up to 5 different methods of infecting computers systems and duplicating itself. It was started in 2001.

SAPPHIRE:

SQL Slammer, also known as Sapphire, was launched on January 25, 2003. It was a doozy of a worm that had a noticeable negative impact upon global Internet traffic. Its target was servers. The virus was a single-packet, 376-byte worm that generated random IP addresses and sent itself to those IP addresses. If the IP address was a computer running an unpatched copy of Microsoft’s SQL Server Desktop Engine, that computer would immediately begin firing the virus off to random IP addresses as well.

Slammer infected 75,000 computers in 10 minutes which is very remarkable. The outrageously high amounts of traffic overloaded routers across the globe, which created higher demands on other routers, which shut them down, and so on.

 BLASTER: 

The summer of 2003 was a rough time for businesses running PCs. In rapid succession, IT professionals witnessed the unleashing of both the Blaster and Sobig worms. Blaster, also known as Lovsan or MSBlast, was the first to hit. The virus was detected on August 11 and spread rapidly, peaking in just two days. Transmitted via network and Internet traffic, this worm exploited a vulnerability in Windows 2000 and Windows XP, and when activated, presented the PC user with a menacing dialog box indicating that a system shutdown was imminent.

Hidden in the code of MSBLAST.EXE — the virus’ executable ” were these messages: “I just want to say LOVE YOU SAN!!” and “billy gates why do you make this possible? Stop making money and fix your software!!”

SOBIG: 

The Sobig worm hit right at the end of Blaster, making August 2003 a miserable month for corporate and home PC users. The most destructive variant was Sobig.F, which spread so rapidly on August 19 that it set a record (which would later be broken by MyDoom), generating over 1 million copies of itself in its first 24 hours.

                   The virus infected host computers via innocuously named e-mail attachments such as application.pif and thank_you.pif. When activated, this worm transmitted itself to e-mail addresses discovered on a host of local file types. The end result was massive amounts of Internet traffic. On September 10, 2003, the virus deactivated itself and is no longer a threat. 

MyDoom : 

For a period of a few hours on January 26, 2004, the MyDoom shockwave could be felt around the world as this worm spread at an unprecedented rate across the Internet via e-mail. The worm, also known as Norvarg, spread itself in a particularly devious manner: It transmitted itself as an attachment in what appeared to be an e-mail error message containing the text “Mail Transaction Failed.” Clicking on the attachment spammed the worm to e-mail addresses found in address books. MyDoom also attempted to spread via the shared folders of users’ Kazaa peer-to-peer networking accounts.

The replication was so successful that computer security experts have speculated that one in every 10 e-mail messages sent during the first hours of infection contained the virus. MyDoom was programmed to stop spreading after February 12, 2004.

DOWNAD : 

The latest and most dangerous virus is the “downadup” worm, which was also called “Conficker”.  computer virus has infected 3.5 million computers worldwide. This malicious program was able to spread using a patched Windows flaw and Vulnerability. Downadup was successful in spreading across the Web due to the fact that it used a flaw that Microsoft patched in October in order to distantly compromise computers that ran unpatched versions of Microsoft’s operating system. But the greatest power of the worm is believed to be the ability of computers, infected with the worm, to download destructive code from a random drop point

Denial Of Service Attack

It is is an attempt to make a computer resource unavailable to its intended users by remote users. This is one of the Botnet Attacks. It generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Creators who use make or program this attack will target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers.

Botnet

A botnet is a collection of software agents, or robots, that run autonomously and automatically. It also refers to a network of computers using distributed computing software. A computer "robot" or "bot" that serves the wishes of some master spam or virus originator. The main motive behind these botnets is financial gain along with recognition. Botnets have become a significant part of the Internet, albeit increasingly hidden. Due to most conventional IRC networks taking measures and blocking access to previously-hosted botnets, controllers must now find their own servers. Sometimes a controller will hide an IRC server installation on an educational or corporate site where high-speed connections can support a large number of other bots.

Hacking Tool

Rootkits are used to hide system information, such as running processes, files, or registry entries. This technology is used in creating a tools that helps in hacking other machines. First 4 Internet Ltd has developed a tool that is a valid Digital Rights Management Software package. As a standalone application, it is non-malicious but some of the malicious application use it to hide their infiltrated files and auto start registry entries thus making the detection more difficult.

This rootkit is  installed in :C:" that is system folder and in windows sub-folder using a file name ARIES.SYS. The said rootkit is then executed as a service by an installation package and is configured to execute at every system startup by creating the following registry entries

• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\$sys$aries 

This hides files folders and registry keys the begin with the string $sys$ in the Windows operating system. This prevents the user from viewing any files, folders and registry keys that begin with the said string.

There are two malware that will utilize this tool BKDR_BREPLIBOT.C , BKDR_BREPLIBOT.D. 

Removal: 

Take a back up of registry before you edit any thing in registry for this tool. Disable System Restore.

1. Open Registry Editor. Click Start>Run, type REGEDIT, then press Enter.
2. In the left panel, double-click the following:
   HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services
3. Still in the left panel, locate and delete the subkey:
   $sys$aries
4. Close Registry Editor.

Scan your computer in safe mode with a good anti-virus like Trend Micro, Symantec to remove the files that are installed by malware that uses this tool and also this tool. Even online scanners like Housecall, Rootkit revealer, avast online scanner etc will detect this tool and will remove it.

Multiple Malware

There are instances where more than one malware infecting at a same time because of many vulnerabilities and many ways that different malware can attack on a PC. It leads to severe situations and that will crash the PC entirely. There is one particular exploit that brings all the malware and trojans at a time HTML_SHELLCOD.SM that exploits CVE- 2010 3962 and because of which following trojans and malware attack the PC:

• TROJ_LAMECHI.D,
• JS_EXPLOIT.ADA,
• JS_EXPLOIT.SM1, 
• HTML_SHELLCOD.SM, 
• TROJ_DLOADER.DAM, 
• TROJ_GAMETHI.FMS, 
• PE_PARITE.A, 
• TSPY_ARDAMAX.HR

HTML_SHELLCOD.SM, a recently discovered malware that took advantage of a certain vulnerability in Internet Explorer (IE) and after all these infections infect the system and it many eagle-eyed cybercriminals look to further to inject their malicious money-making machinations that exploits all of the vulnerabilities present in the most efficient way possible.

Once HTML_SHELLCOD.SM has successfully taken advantage of the Uninitialized Memory Corruption Vulnerability (CVE-2010-3962) in IE, it connects to various URLs to download other malicious files detected as TROJ_LAMECHI.D, JS_EXPLOIT.ADA, JS_EXPLOIT.SM1, HTML_SHELLCOD.SM, TROJ_DLOADER.DAM, TROJ_GAMETHI.FMS, PE_PARITE.A, and TSPY_ARDAMAX.HR onto the affected systems.

This malware can render an infected system unusable.and puts the user’s confidential information at risk if another malware with backdoor capabilities affect the system. For instance, TROJ_GAMETHI.FMS, one of the malware HTML_SHELLCOD.SM downloads, steals user names and passwords related to popular online games such as Maple Story, Dungeon Fighter, Ragnarok Online, and World of Warcraft and can compromise the user accounts.

TSPY_ARDAMAX.HR will drop a file named TROJ_GAMETHI.FMS which drops more files on the infected system.  It also logs keystrokes and accesses certain sites and hacks chat logs which compromises user's privacy by stealing usernames and passwords. TROJ_GAMETHI.FMS terminates processes and downloads component files.

 PE_PARITE.A is a malware that infects .exe and .scr fils and spreads the entire network drives by choosing a port.

Prevention: 
Users can prevent this threat by updating their operating system with all the available patches and updating their anti-virus with latest updates. Scan the PC with the updated Malware by disabling system restore, it will remove the threat.

20th Century's Most Dangerous Infections

Viruses saw light and managed to cause serious damages to unprepared users and their machines. Millions of users downloaded computer viruses without even knowing about it. Hackers used various ways of penetrating the systems of universities from around the world, even NASA, armed Forces and Government Sites.It shows the increased level of mastery in writing virus programs, malware or hacking methods.


Jerusalem
The virus was named Jerusalem because it was identified in a Hebrew university. For the first time it was discovered in 1987 on October 1, but in 1991 antivirus experts found that Italy is the country where the first traces of the computer virus were noticed. Initially the Jerusalem virus included a bug that led to a repeat infection of the files that continued until the size of the files overcome computer resources. In addition, each Friday 13 it deleted all programs in the infected system as a result of a malicious payload that set off on the respective day. Jerusalem considerably slowed down the machine. A person could identify the virus but noticing two lines on the monitor.

 


Morris or  Internet Worm:
We wrote about this computer worm, which is believed to be one of the first worms that spread over the Internet. The name of the virus comes from its developer Robert Tappan Morris, who was a student at Cornell University. The computer worm was set off on November 2, 1988 and after some time it managed to infect 6,000 to 9,000 machines. It overloaded the whole Internet, leading to the failure of a large number of servers. According to its developer, the goal was to discover just how far and fast a computer worm can spread all over the network. Robert Tappan Morris was found guilty and sentenced to 3 years of probation along with 400 hours of community service. In addition, he had to pay a $10,000 fine.

CIH or Chernobyl:

CIH virus that caused an estimated damage of $20 to $80 million around the globe, the computer virus managed to affect huge amounts of data stored on computers. Later it was discovered that the computer virus was launched in Taiwan. It has been recognized to be one of the most dangerous computer viruses in history that has infected Windows 95, 98, and ME executable files. In addition, CIH remained resident in the memory of the machine, being able to carry on infecting other executables. After being activated, the virus overwrote data on the HDD of the infected PC, making the latter inoperable. CIH could also overwrite the BIOS of the infected computer, thus preventing boot-up. The second name of the virus - Chernobyl - was given because some of the biggest damages occurred on the day when the nuclear reactor exploded.

Solar Sunrise :
It is the name of the situation that occurred in 1998 when a team of hackers managed to take control of more than 500 computer system of the army, government as well as private sector of the United States. The name Solar Sunrise comes after the well-known vulnerabilities in machines that run on the Sun Solaris OS. At first the attack was believed to have been organized by hackers from Iraq, but later it was discovered that the ones to blame were two American youngsters from California.


Barrotes - 1993:
This is believed to be the first popular computer virus developed in Spain. As soon as it infected the system, it would remain there until January the 5th, when it would set off showing a series of bars on the screen. It infected .COM, .EXE and overlay files. The Barrotes computer virus represents a resident virus - it becomes a resident of the computer memory each time the machine starts up. Due to a series of vertical lines that appear on the monitor, it was easy to identify the virus. It could also overwrite the Master Boot Record of the HDD, thus making it impossible for the uses to access the hard disk.

There are many more viruses that are dangerous and damages the system very badly. We need to get a good anti-virus that has good search engine and which updates regularly and protects our computer.
