After poking around the Windows Vista networking stack, Symantec researchers have tried out privilege-escalation attacks on an early version of the Windows XP successor. In a second report on Vista, Symantec takes on a security feature called User Account Control (UAC), in the operating system.

"We discovered a number of implementation flaws that continued to allow a full machine compromise to occur," Matthew Conover, principal security researcher at Symantec, wrote in the report titled "Attacks against Windows Vista's Security Model."
