The flaw, which allows hackers to infect computers using programs maliciously inserted into seemingly innocuous image files, was first discovered last week. But the potential for damaging attacks increased dramatically at the weekend after a group of computer hackers published the source code they used to exploit it. Unlike most attacks, which require victims to download or execute a suspect file, the new vulnerability makes it possible for users to infect their computers with spyware or a virus simply by viewing a web page, e-mail or instant message that contains a contaminated image.
Yes, that’s right, merely viewing an infected image can open up your machine to hackers.
No need to say what could be said about Microsoft. If you use Windows, stay frosty and be careful of what you click on (as you should anyway). Meanwhile, I’ll click whatever I darn well please with wanton abandon.
