Flashback trojan, (Backdoor.Flashback.39) an Apple’s Mac malware that has affected more than 500,000 Mac computers in the world, is considered to be the largest Mac malware threat ever in the history of Apple.
[hana-code-insert name=’StumbleUpon’ /][hana-code-insert name=’Reddit’ /] Dr. Web reported that more than half of the infected computers are located in U.S and almost 20% in Canada. It has been reported that more than 98% of affected computers were operating on Mac OS X.
“600,000 represents around 12 percent of the Mac OS computers sold in Q4 2011,” Catalin Cosoi, chief security researcher for antivirus-software maker Bitdefender, said, “which means that if we count the number of Mac OS devices sold in the past three years, we can estimate that less than 1 percent of the Mac OS computers are possibly infected. On the other hand, if we look at the actual numbers and not at the percentages, the numbers look pretty scary.”
Many of the Apple computers have java installed on them, which is making them vulnerable to Flashback. However, Apple has posted a security fix for Mac OS X Lion and Mac OS X Snow Leopard.
