Symantec: Flashback malware from Apple OS X devices has seen the number of infected machines decline from more than 600,000 at the peak of the infection. Apple released an automatic operating system upgrade Friday for OS X 10.6 and 10.7. Apple also included a feature that disables Java if it hasn’t been used for 35 days. Flashback targets a Java vulnerability that was apparently reverse-engineered by attackers after Oracle patched the same flaw in Windows. The malware can receive command and control (C&C) server contact details via Twitter.”]
