Cyber Criminals Create Botnet Using Mac Computers
Via CBC News.
A piece of malicious software unwittingly shared over a peer-to-peer network in January was the key tool in what security researchers are saying was the first known attempt to create a botnet of Mac computers.
Researchers at Symantec say the Trojan, called OSX.Iservice, hid itself in pirated versions of the Apple application iWork '09 and the Mac version of Adobe Photoshop CS4 that were shared on a popular peer-to-peer bittorrent network.
Once downloaded, the applications themselves worked normally, but the Trojan opens a "back door" on the compromised computer that allows it to begin contacting other hosts in its peer-to-peer network for commands.
Researchers Mario Barcena and Alfredo Pesoli of Symantec Ireland, writing in the April 2009 issue of the Virus Bulletin, say the network of infected computers attempted to initiate a denial of service attack on a website in January.
