I’ve been an on again/off again user of Internet Explorer, and think I am staying with IE9 (for now!). But, IE users are most at risk for DLL highjacking attacks. I’m not sure if this will affect IE9, but it makes sense to stay updated. There have been times when Firefox has been hit with a big vulnerability and I jump ship to Opera or Chrome until it is fixed, and I don’t mind doing it with IE9 if needed.
When running on Windows XP, Internet Explorer 6 (IE6), IE7 and IE8 do not warn users when they click on a malicious link that automatically downloads a malicious dynamic link library, or DLL, to the PC, said Mitja Kolsek, the CEO of Slovenian security company Acros Security.
