Ever since, it has exploited three distinct vulnerabilities in Java (CVE- 2011 - 3544, CVE – 2008 - 5353, and CVE – 2012 – 0507 ), the latter being patched earlier this April. The Flashback Trojan was initially spotted in September 2011, when it would pose as a Fake Flash Player installer. This Trojan has a backdoor capability (which means an attacker can seize full control of your Mac) and also tries to harvest usernames and passwords used for services such as Gmail, PayPal, and e-banking, amongst others. As the user lands on the compromised page, a piece of Javascript code loads a Java applet that exploits the locally-installed version of Java. Successful exploitation leads to the download and execution of a malicious file identified by Bitdefender as .L. The malicious code is known to be hosted on websites that advertise themselves as user-generated video services. Identified earlier last week, the Flashback.L Trojan is thought to have infected more than 6,00,000 OS X computers worldwide already by exploiting the Java runtime environment on the local machine.

Bitdefender has announced a new virus scanning software that offers detection and removal for the latest e-threat affecting Mac OS X users. About BIOS Update Utility: Applying a new BIOS version can bring various fixes, add new features, or improve existing.

We had reported earlier how the Flashback trojan had infected 5,50,000 Macs worldwide but now we have some good news for Mac users. The Flashback Trojan was initially spotted in September 2011, when it would pose as a Fake Flash Player installer.
