Computerworld News: “ . Microsoft today warned that attackers could exploit a critical unpatched bug in Internet Explorer, first reported in May, and take over a user’s computer.”
“Microsoft Corp. is warning Internet Explorer users to be careful where they browse because attackers are now targeting a critical unpatched bug in the software. If successful, these attackers could possibly use this bug to seize control of a user’s system, the company said.”
“Be careful?” With clever phishing schemes, unicode obfuscation of URIs, DNS poisoning and adware injection, it’s not possible to “be careful.” Just don’t use IE.
