The latest Internet Explorer “Zero-Day” vulnerability, first acknowledged by Microsoft on Saturday, April 26th, has left all version of Internet Explorer 6 through 11 vulnerable to exploitation. However, initial reports indicate that IE versions 9, 10, and 11 are the primary targets. According to the research firm FireEye, the exploit uses an Adobe Flash SWF file to execute the exploit. Machines that do not have Flash installed are believed to be safe. It is important to note that Microsoft will not be producing a patch for its Microsoft XP operating system. Support for this OS ended on April 8, 2014 so if you’re running this operating system on your machine, you will need to upgrade.
If you currently have a Thrive Managed Firewall powered by Dell SonicWALL, the Intrusion Prevention signatures to cover the “Zero-Day” exploit were added to your device within the last 48 hours. You are protected from this vulnerability when on the Internet behind your corporate firewall. (more…)
