Trojan virus targets Mac users 2 Nov 2007, SMH - Online porn-hunters are the intended victim of the latest ploy, in which visitors to certain explicit websites are led to believe they're downloading a video-decoding plug-in when in fact they are installing malicious code onto their Macs.

Once the user authorises the transaction, the fraudsters can redirect his future browsing to fraudulent websites and possibly to steal his information or passwords or simply send ads for other pornographic websites and rake in advertising US dollars.

For example, a person using an infected computer may thinks he is going to online auctioneer eBay or its PayPal electronic payment division but actually be directed to a site that looks legitimate but exists to purloin personal information.

The attack does not target a vulnerability in the Macintosh operating system.

Instead, it requires a user to approve the download, then enter his computer's administrator's password to continue, operations that raise red flags among sophisticated computer users.
