Critical Internet Explorer Bug Threatens Users

If you run Internet Explorer versions 6 to 11, then you need to switch to another browser until Microsoft patches a bug that is so serious, it’s already being used for evil according to The Globe And Mail:

Microsoft disclosed on Saturday its plans to fix the bug in an advisory to its customers posted on its security website, which it said is present in Internet Explorer versions 6 to 11. Those versions dominate desktop browsing, accounting for 55 per cent of the PC browser market, according to tech research firm NetMarketShare.

Cybersecurity software maker FireEye Inc said that a sophisticated group of hackers have been exploiting the bug in a campaign dubbed “Operation Clandestine Fox.”

FireEye, whose Mandiant division helps companies respond to cyber attacks, declined to name specific victims or identify the group of hackers, saying that an investigation into the matter is still active.

The bug allows “limited remote code execution.” That means that someone can run commands to do things on your PC from someplace else. Given that Microsoft is being open about this bug, it’s serious and you should treat it as such. Expect a patch for this before Microsoft’s usual “Patch Tuesday” cycle in May. Unless of course you’re an XP user in which case you’ll get nothing. Thus you’ll likely have to switch to some other browser. Something that may not be a bad idea for any user of Internet Explorer.
