BEIJING, Feb.17 (Xinhuanet) -- A mischievous computer worm has been
found to hit Apple's OS X operating system, believed to be the first
such virus ever to target the Mac platform.
Called OSX/Leap-A, the worm is spread via instant messaging programs,
according to a posting on the Web site of antivirus software company
The virus is said to spread using Apple's iChat IM service, forwarding
itself as a file called "latestpics.tgz" to an infected user's buddy
contacts, according to the Sophos Web site.
Clicking on the file allows the malware to install and disguise itself
as a harmless-seeming Jpeg icon.
"This first Macintosh OS X threat is an example of the continuing
spread of malicious code on to other platforms," said Vincent Weafer,
senior director at Symantec Security Response, in a statement.
The worm will not automatically infect Mac computers, but will ask
users to accept the file, Weafer said.
Symantec has rated the worm a low-risk security threat.
