With Windows 7, the latest version of Microsoft Windows, reaching general retail availability on October 2009, it was just a matter of time before malware creators rose to the occasion, and exploited users ‘eagerness to install it on their PCs.
A deceptive “help” message invites recipients to check their PCs’ compatibility with Windows® 7 by downloading and running an altered version of Windows 7 Upgrade Advisor concealing a Trojan.
Instead of the promised compatibility checking tool, the zip file hides Trojan.Generic.3783603. This piece of malware contains malicious or potentially unwanted software which it drops and installs on the system. Frequently, it installs a backdoor which allows remote, clandestine access to the infected system. This backdoor may then be used by cybercriminals to upload and install additional malicious or potentially unwanted software on the captured system.
Once a victim has installed the software, criminals can pretty much do whatever they want on the PC, Cosoi said. That could mean installing a keylogger to steal banking credentials or even gaining full access to the hacked system.
