Twenty-five percent of all internet browsing activities are done using Internet Explorer. This make it especially dangerous since Microsoft has confirmed a new zero day vulnerability that effects every version of the software on very device.
Attacks that are occurring are largely targeting IE versions 9, 10, and 11. Called “use after free attacks,” these scams typically lure users into visiting unsafe websites in order to obtain information and power over their computer or mobile device:
The vulnerability is a remote code execution vulnerability. 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.
Microsoft is expected to release a an out-of-cycle security patch soon. In the meantime, be wary of phishing scams and don’t visit links you are not sure about. This seems most precarious for those on work computers or on large government networks.
