Hackers crack Gmail’s CAPTCHA

Posted by Wolfgang Gruener

Security firm Message Labs today said that there is a lot more spam from Gmail accounts coming your way – which is a result of hackers having cracked Google’s CAPTCHA identity verification tool. MessageLabs claims that the breaking rate of the CAPTCHAs is somewhere between 20 and 30%, which is good (or bad, depending on your view) enough to create lots of new accounts to flood your email inbox. The proportion of spam originating from Google accounts has doubled in February, climbing from 1.3% in January to 2.6% in February.  

 

Yahoo Mail still accounts for the most spamming accounts - 88.7%, according to MessageLabs. Yahoo! Mail and Hotmail CAPTCHAs were first broken in July 2007.
