-How CAPTCHA virus works?
Flash_Update.exe downloads a couple of executables: google_reg.exe and captcha.exe from aibcvienna.org, which appears to be a legitimate website compromised by the hackers, into the affected system. It’s important to note that the domain also includes other executables tailored for hi5 and Myspace users.
The file google_reg.exe attempts to create new Google accounts, where it needs the help of humans in reading the CAPTCHA. It uploads the CAPTCHA image to a server and waits for captcha.exe to download it. The captcha.exe drops a file named captcha5.dll into the Program Files directory and runs it using rundll32.exe, a system file used for executing .dll files. The dropped dll file displays a shutdown window which freezes the system and threatens the user to enter the characters seen in an image before a 3 minutes countdown timer ends. The image is in fact the CAPTCHA that google_reg.exe is waiting for to be deciphered by the victim.
