Det er oppadaget et nytt hull i Windows, som gjør at virus kan overføres bare ved å se på et bilde.
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.
The potential [security threat] is huge,» said Mikko Hyppönen, chief research officer at F-Secure, an antivirus company. «It’s probably bigger than for any other vulnerability we’ve seen. Any version of Windows is vulnerable right now.»
