Fake Anti-Virus Keygen Steals Information

A security researchers from Kaspersky lab found a keygen for Kaspersky product which bundeled with trojan and steal information from users system.

This keygen was recently spotted on file sharing websites and promises to generate serial keys for Kaspersky Anti-Virus 2010, Kaspersky Internet Security 2010 and Kaspersky Simple Scan 2010. This Trojan dropper file name is kaspersky.exe.

Once launched, the file displays a key generator window prompting the user to select a product. After one of the options is selected, the program proceeds to generate a key.

While the freebie lover is waiting for the result, two pieces of malware that were stealthily installed and launched by the dropper make themselves at home on the PC.

One of these is detected by Kaspersky Lab as Trojan.MSIL.Agent.aor. It steals registration data for other programs, as well as passwords, mostly for online games. It rather considerately stores all the stolen data in one file.

One of these serial key stealer that targets a wide variety of programs and games including TechSmith SnagIt, Texas Calculatem 4, The Battle for Middle-earth, The Orange Box, TMPGEnc DVD Author, TuneUp 2007, 2008 and 2009, Winamp, The Sims 3, Spore, Mirrors Edge, GTA IV, FIFA 2008 and 2009, and Pro Evolution Soccer 2009.

The Trojan also modifies the ‘hosts’ system file to block access to a number of websites. For example, such websites as virustotal.com and virusscan.jotti.org, which offer file scanning by solutions from many antivirus vendors, become inaccessible.

The second piece of malware installed by the dropper is a typical backdoor which also has keylogger functionality, collecting keystroke data. It is detected as Trojan.Win32.Liac.gfu.

Thus, running a supposed key generator for Kaspersky Internet Security will plant a couple of very real malicious programs on your computer, which KIS will then have to deal with. Provided, of course, that the keys generated by the ‘keygen’ actually work.
