Hackers are now exploiting the zero-day Windows vulnerability that a Google engineer took public last week, Microsoft confirmed today.
Although Microsoft did not share details of the attack, other researchers filled in the blanks.
A compromised Web site is serving an exploit of the bug in Windows' Help and Support Center to hijack PCs running Windows XP, said Graham Cluley, a senior technology consultant at antivirus vendor Sophos. Cluley declined to identify the site, saying only that it was dedicated to open-source software.
"It's a classic drive-by attack," said Cluley, referring to an attack that infects a PC when its user simply visits a malicious or compromised site. The tactic was one of two that Microsoft said last week were the likely attack avenues. The other: Convincing users to open malicious e-mail messages.
