  • Flashback Trojan Reportedly Infected Roughly 600,000 Macs Worldwide


    Roughly 600,000 Macs around the world have been infected with a trojan horse virus named “Flashback” that surfaced last year and is believed to have created a botnet. The Russian antivirus company named Dr. Web issued a report recently noting that 550,000 computers running on mac OS X had been infected by BackDoor.Flashback variants of the virus.

    An analyst of the company update the figure to note that the size of the botnet had reached 600,000 and pointed out that 274 bots are originating from Apple’s hometown of Cupertino, California. According to a map released by the firm, 56.6% of the infected computers are located in the United States. Canada was second with 19.8% followed by the U.K. with 12.8% of cases.

    Apple recently released a Java Security update to resolve the vulnerabilities that the virus was exploiting, but unfortunately the virus had managed to infect a number of Mac users with the malicious software. Oracle first issued a fix for the vulnerability in February, which not too many people were able to utilize either.

    The Flashback Trojan was first publicized in October with variants of the software even found disabling anti-malware protections within OS X. Researchers at F-Secure have provided instructions on how you can detect and remove the malware from your computer for those of you who are suspicious of being infected.

      ClamxAV is a much better option for a free antivirus.

      Get the one from their site not the appstore. The appstore version does not have the sentry; which is a live scanner to watch a folder i.e. download folder.

      ClamXav


      Avoid Sophos at all costs. It will actually make you more vulnerable. It's update part runs as admin.

      Or use nothing and be aware of what you are doing on the web and have the "automatically update safe downloads list" in the preference>security panel.

      The link in the article: Threat Description: Trojan-DownloaderSX/Flashback.I

      Also note if you have any of these installed it auto canceled itself at the start. It checks to see if you have these apps installed:

      /Library/Little Snitch
      /Developer/Applications/Xcode.app/Contents/MacOS/Xcode
      /Applications/VirusBarrier X6.app
      /Applications/iAntiVirus/iAntiVirus.app
      /Applications/avast!.app
      /Applications/ClamXav.app
      /Applications/HTTPScoop.app
      /Applications/Packet Peeper.app

      It also check for :

      /Applications/Microsoft Word.app
      /Applications/Microsoft Office 2008
      /Applications/Microsoft Office 2011
      /Applications/Skype.app


      I use littlesnitch myself anyway.

      The only reason Macs did not get viruses in the past was because the installed Mac user base was too small for virus writers to bother with. Now that Mac is much more popular, there will be viruses. There was never any "magic" about being a Mac that kept viruses away.

      That's not the main reason. It actually plays a small role in the reason but still a small reason. It has to do more with it being built on Unix and how Unix handles permissions. If you notice most of this trojan required the input of admin password to work. OS9 was riddled with actual viruses and it had a small footprint too. That's because it was not built on top of Unix.

      (BTW I LOVE corgis. Hope to get one some day.)
