Remember when your favorite 'computer expert' (nerd) told you not to use Internet Explorer(IE)? Probably also recommended using Chrome or Firefox? Well don't come crying to them when your PC is all crapped up. DL links below.

According to a confirmation by Microsoft late last night, a new zero day vulnerability has been found to affect every version of Internet Explorer. In other words—over a quarter of the entire browser market.

Attacks taking advantage of the vulnerability are largely targeting IE versions 9, 10, and 11 in something called a "use after free" attack. Essentially, the attack corrupts data as soon as memory has been released, most likely after users have been lured to phony websites. Microsoft explains:

The vulnerability exists in the way that Internet Explorer accesses an object in memory that has been deleted or has not been properly allocated. The vulnerability may corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user within Internet Explorer. An attacker could host a specially crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website.

Get Chrome:

Linux and OSX users need only be concerned if they run a version of Windows in a VM like VMWare or VirturalBox.
