Mac Flashback Abusing Unpatched Java for OS X

Cyber criminals have come up with password-stealing malwares that exploits java vulnerabilities Apple that has been slow to fix, despite concerned of the fact that the security flaw since February 2012, CNR reported this news on April 2, 2012.

Initially, the malware is reported to be found in September 2011, when it was being circulated as a forged flash player installer (hence the name "flashback").

As the exploits employed by the latest variants of the flashback malware has been quite an older version, but of recent another variant surfaced the air taking full-on advantage of the java vulnerability (CVE -2012-0507), which is unpatched recently in the OS X..
