Hackers mind: not Microsoft only

While hackers continued to poke new holes in Microsoft's popular Windows operating system, they increasingly exploited flaws in software made by other companies as well, the nonprofit SANS Institute found. As more Windows users agreed to receive security upgrades automatically, hackers looked to take advantage of other software programs.

Operating systems have gotten better at finding and fixing things and auto-updating, so it's less fertile territory for the hackers," said SANS Chief Executive Alan Paller.  Anti-virus products from Symantec Corp, F-Secure, TrendMicro and McAfee proved vulnerable as well.
