Over half a million Apple Mac computers have been infected with a computer trojan that connects them to an extensive botnet largely based in North America.

Over half a million Apple Mac computers have been infected with a computer trojan that connects them to an extensive botnet largely based in North America.

 
Russian anti-virus software firm Doctor Web found that the BackDoor.Flashback trojan is spreading quickly on Mac computers, taking advantage of a Java exploit employed on rogue websites, all of which appear to employ the .rr.nu extension. This exploit saves an executable file on infected computers, which downloads further malware and establishes the Mac as part of the growing botnet.
 
A whopping four million websites are believed to be compromised and hackers are constantly adapting their exploits to continue the spread of malware. They used two security holes in February and then switched to a third after 16 March, which Apple only repaired a few days ago. Further exploits will likely be identified and employed over the coming weeks and months.

Apple's computers and devices are usually well-known for their higher security compared to Windows-based computers, with less malware circulating. This reputation has even led some to believe they do not need anti-virus software on a Mac. Much of this security complacency is to blame for the spread of malware on Apple machines, and it highlights the closing gap between Macs and Windows computers in terms of security.
 
The vast majority of infections are in the United States, with 56.6 percent of the share, followed by Canada, the United Kingdom, and Australia at 19.8 percent, 12.8 percent and 6.1 percent respectively. All other regions show a less than one percent infection rate.
