Stripper Used to Break Security System
The battle between malicious software makers and computer security companies has taken a new turn. Spammers have turned users against themselves and against the security firms trying to protect them.
The latest security system to undergo assault by spammers is CAPTCHA, or "Completely Automated Public Turing Test to Tell Computers and Humans Apart." CAPTCHA displays a series of letters and number that are distorted and overlaid with visual artifacts (as seen above) in order to prevent automated systems from sending spam, hijacking services, and overtaking forums and blogs. You've probably seen these optical illusions countless times when signing up for a variety of services.
The new tool -- also known as malware -- in the spammers box of tricks is a PC program that shows pictures of a woman in increasingly scanty states of undress each time users correctly spell out these scrambled images of letters. This malware program arrives via e-mail and shows up on your computer as soon as you open the Internet Explorer Web browser.
The woman, called Mellisa, is currently being used to help spammers break through the protection on Yahoo! Mail sign ups, but it's not hard to imagine its use becoming more widespread soon.
We shouldn't have to say it, but here's how you can prevent these types of malware scams from infecting your computer: Run spyware removal software and virus scans on a regular basis, don't open e-mails or attachments from unfamiliar sources, and immediately remove any software if you don't know where it came from.
