Mac computers 'infected with malware'

Mac computers 'infected with malware'

More than half a million Apple computers have been infected with the Flashback Trojan, according to a Russian anti-virus firm.

Its report claims that about 600,000 Macs have installed the malware - potentially allowing them to be hijacked and used as a "botnet".

The firm, Dr Web, says that more than half that number are based in the US.

Apple has released a security update, but users who have not installed the patch remain exposed.

Flashback was first detected last September when anti-virus researchers flagged up software masquerading itself as a Flash Player update. Once downloaded it deactivated some of the computer's security software.

Later versions of the malware exploited weaknesses in the Java programming language to allow the code to be installed from bogus sites without the user's permission.
Remote control

Dr Web said that once the Trojan was installed it sent a message to the intruder's control server with a unique ID to identify the infected machine.

"By introducing the code criminals are potentially able to control the machine," the firm's chief executive Boris Sharov told the BBC.

"We stress the word potential as we have never seen any malicious activity since we hijacked the botnet to take it out of criminals' hands. However, we know people create viruses to get money.

"The largest amounts of bots - based on the IP addresses we identified - are in the US, Canada, UK and Australia, so it appears to have targeted English-speaking people."

Dr Web also notes that 274 of the infected computers it detected appeared to be located in Cupertino, California - home to Apple's headquarters.
Update wait

Java's developer, Oracle, issued a fix to the vulnerability on 14 February, but this did not work on Macintoshes as Apple manages Java updates to its computers.

Apple released its own "security update" on Wednesday - more than eight weeks later. It can be triggered by clicking on the software update icon in the computer's system preferences panel.

The security firm F-Secure has also posted detailed instructions about how to confirm if a machine is infected and how to remove the Trojan.

Although Apple's system software limits the actions its computers can take without requesting their users' permission, some security analysts suggest this latest incident highlights the fact that the machines are not invulnerable.

"People used to say that Apple computers, unlike Windows PCs, can't ever be infected - but it's a myth," said Timur Tsoriev, an analyst at Kaspersky Lab.

Apple could not provide a statement at this time.
