First IE Zero-Day Post-Windows XP Affects a Quarter of Internet Users

“This is the first major known exploit of a vulnerability to affect Windows XP since the official end of support earlier this month,” said Simon Townsend, chief technologist of Europe at AppSense, in a comment to Infosecurity. “Recent research from AppSense suggests that as much as 77% of British businesses are running Windows XP in some capacity beyond the end of support deadline. Such organizations could be impacted by further exploits to this vulnerability as malware creators take further advantage of this security hole which will remain open, due to the end of patches and security fixes for Windows XP by Microsoft.”
