Captcha buster spreads
By John Leyden
Published Wednesday 15th August 2007

A strain of malware capable of setting up bogus Hotmail and Yahoo! accounts in order to send spam has been adapted to also target Gmail accounts.

The HotLan Trojan creates automatically-generated webmail accounts, implying that spammers have discovered a means to defeat Captcha challenge-response systems. Captcha systems, which typically prevent accounts being created until a user correctly identifies letters depicted in an image, are designed to ensure requests are made by a human rather than an automated program.
