NEW YORK (CNNMoney.com) - The new year is off to a rocky start at Microsoft,
where security experts are scrambling to confront a potentially massive
virus threat to Windows PCs.
According to a report Tuesday in the Financial Times, the latest
vulnerability involves a flaw which allows hackers to infect computers using
programs inserted into image files. The threat was discovered last week. But
it mushroomed over the weekend, when a group of hackers published the source
code they used to exploit the flaw.
What makes this threat particularly vicious, according to the Times, is that
unwitting victims can infect their computers simply by viewing a web page,
e-mail, or instant message that includes a contaminated image. That differs
from most virus attacks, which require a user to actually download an
infected file.
"The potential [security threat] is huge," Mikko Hypponen, chief research
officer at F-Secure, an antivirus company, told the Times. "It's probably
bigger than for any other vulnerability we've seen.
"Any version of Windows is vulnerable right now," said Mr. Hypponen,
including every Windows system shipped since 1990.
Microsoft said a security patch would be available for the problem on
Tuesday, January 10 after it has passed rigorous testing procedures
