When bots started spreading over the Internet scene a few years ago, security experts fought back with a system dubbed as “Completely Automated Public Turing test to tell Computers and Humans Apart,” or more popularly known as the CAPTCHA. The system was aimed at preventing automated submissions/registrations by prompting the user to validate himself as a human, usually requiring the user to input a sequence of alphanumeric characters contained in an image supposedly “unreadable” by a machine.
However, some people are really hooked up on defeating the CAPTCHA, and they are literally asking for public help, in a rather discreet —and, uhm, provocative— manner.
A nifty little program which Trend Micro detects as TROJ_CAPTCHAR.A disguises itself as a strip-tease game, wherein a scantily-clad “Melissa” agrees to take off a little bit of her clothing. However, for her to strut her stuff, users must identify the letters hidden within a CAPTCHA. Input the letters correctly, press “go” and “Melissa” reveals more of herself.
