It looks as though hackers are already exploiting that Windows flaw that was disclosed by Google yesterday. The attacks exploit a vulnerability in Adobe Flash and one in the Windows. Microsoft Corp said on Tuesday that a hacking group previously linked to the Russian government and U.S. political hacks was behind recent cyber attacks that exploited a newly discovered Windows security flaw. The software maker said in an advisory on its website there had been a small number of attacks using "spear phishing" emails from a hacking group known Strontium, which is more widely known as "Fancy Bear," or APT 28. Microsoft did not identify any victims.
