Dr. WEB Diagnosed 550K Macs Infested With “Flashback”
The Russian anti-virus vendor, Doctor WEB, released on Wednesday a research reporting that the Trojan BackDoor.Flashback reached to 500 000 of Apple’s hardware running Mac OS X. Mac owners from the U.S., Canada and UK were the most injured.
BackDoor.Flashback.39 gets installed in someone’s computer once a user reaches an infested link, and it seems that more than four million infested Web pages were found on a Google SERP at the end of March.
When it reaches a Mac, Flashback automatically saves on its hard drive an exe. file that adds malicious charges to the system. If the Trojan analyzes your system’s field and if the immunity is low, it successfully installs and starts downloading and running payloads.
In order to keep the track of the infected hosts, Dr. WEB redirected the botnet traffic to its own servers. It seems that the compromised Mac owners were mostly from the U.S., Canada and UK.
Apple closed this vulnerability on April 3rd, 2012.
