[pchelpers] News:Spammers beat new Microsoft CAPTCHA defences

Compromised Microsoft accounts are very valuable to spammers, which
means that theyʼll constantly try and break in using new techniques.

Security firm Websense has claimed that new CAPTCHA techniques reworked
by Microsoft at the end of last year have already been busted by
spammers.

CAPTCHA (Automated Public Turing Test to tell Computers & Humans Apart)
was developed in 2000 to stop spam robots. Websense said that recent
Microsoft efforts to rework it and achieve a balance between security
and usability had failed.

The problem was that every time Microsoft tried to implement CAPTCHA
changes to prevent spammers from breaking in and getting control of
accounts, the criminals managed to adapt and beat them.
