CNET News.com: "Competing hacker groups in Russia were peddling the exploit code responsible for the Windows Meta File attacks last December for $4,000, according to security company Kaspersky Lab.
'One of the purchasers of the exploit is involved in the criminal adware/spyware business,' read a Kaspersky Lab quarterly report released this week. 'It seems likely that this was how the exploit became public.'
