Apple has released its first statement regarding the malicious software called Flashback that has plagued more than half a million Macs worldwide.
Apart from acknowledging the issue, Apple pointed to the culprit: a security flaw in Java.
Last week, the company released patches to prevent Flashback's attacks but the fight against the vicious Trojan still goes on. "Apple is developing software that will detect and remove the Flashback malware," reads the official statement.
In addition to the Java security flaw, Flashback also relies on computer servers hosted by the malware authors.
In order to defeat this threat, Apple is working with Internet service providers around the world to disable the dangerous servers.
Until a powerful tool is released, users of machines running on Mac OS X v10.5 or earlier versions are advised to disable Java in the web browser preferences. The Flashback is the widest attack on Macs until now.
As a consequence, Mac OS seems to have lost its reputation as a virus-free environment. Dave Marcus from McAfee Labs explained for AFP:
"All the stuff the bad guys have learned for doing attacks in the PC world is now starting to transition to the Mac world. Mac has said for a long time that they are not vulnerable to PC malware, which is true: they are vulnerable to Mac malware."
