Beware of this new Trojan that spreads through the internet. It exposes a 0day vulnerability on Microsoft Internet Explorer (CVE-2010-0249) which steals information on corporate networks. It allows remote code execution on infected machines.

What’s 0day?
Well basically it’s a security hole that is discovered by geeks or hackers that there is no available fix or update yet.

Microsoft rated it as Critical and they have already issued a fix on this Trojan. Affected versions are Microsoft Internet Explorer 5, 6, 7 and even Microsoft IE 8. You can view the full list of affected Microsoft Internet Explorers here and also download their updates/fixes on the issue.

If you are using Microsoft IE to browse the web, I suggest you update it before everything else is too late. Or, use an open-source browser like Mozilla Firefox or use Google Chrome. There’s a bunch of free web browsers floating on the web, you just have to choose one. But I suggest those to I’ve just mentioned above, or better yet, update your anti-virus virus databases.
