Mac users had been enjoying a virtually virus- and malware-free platform. That was before. Recent virus attacks have been targetting the previously-thought safe and immune Mac platform. As the Mac gains popularity, it become vulnerable to malware attacks as creators of these softwares deviate their attention to this platform.
As experts say, this recent vulnerability of Mac OS has been due to lack of development of anti-malware products, not because of the inherent security of the OS.
The iServices.A Trojan horse is an attack being distributed via BitTorrent, where it’s disguised as a bootleg copy of the new iWork 09. Once installed, the malware takes administrator access and connects to remote servers over the Internet, where it can be given additional instructions as the author commands, from installing additional malware to stealing information off the Mac in question. The malware creator can also take complete remote control of any compromised machine.
Intego reports that 20,000 and more have been affected by the iServices.A Trojan horse and the number continues to increase.
Because these attacks come from downloading pirated software from Torrent sites or any warez sites, Mac users are therefore advised to avoid doing these illegal downloading practices. As is true to Windows users who have also been having similar problem.
