Flashback malware update

Apr 09 2012

On April 4, a Russian antivirus company called Dr. Web announced variations of the Flashback trojan have infected more than a half a million Macs worldwide. The Flashback trojan has been in circulation since 2011, but this particular strain targets a Java vulnerability that was patched by Oracle back in February 2012. Last week, Apple released two Java updates in just three days (Available in OS X Software Update).

An application published on Github can simplify the Flashback detection process and may be downloaded here (Note: it will not remove the trojan). Additional detection tools and in-depth discussions can be found on various Mac blogs, including Ars Technica.

Bottom Line, while Macs are still more secure than most Windows based PC, there are still risks. A few tips to reduce your vulnerably:

  • Keep your software up to date.
  • Consider installing Anti-Virus software such as Sophos for Mac: Home Edition .
  • Avoid websites that are likely to expose you to these threats (websites that host explicit adult content, gambling and illegal software downloads).
