IT security firm Sophos is warning Internet users not to be tempted by a malicious spam campaign which is distributing a Windows Trojan concealed as a game for the popular Apple iPhone.

Samples intercepted by SophosLabs carry various subject lines, including: 'Virtual iPhone games!' and 'Apple: The most popular game!'  The spam emails contain an attachment file called ''.  Unsuspecting users, who may be familiar with the Penguin Panic game for the iPhone, are advised not to open the attachment which contains a Trojan horse, designed to seize covert access to the victim's machine.
Sophos experts note that the Trojan only works on Windows PCs and they have not yet seen versions that will run on Mac OS X, Apple iPhone or other mobile devices.
"Many people who enjoy playing these sometimes innovative and addictive iPhone games may be tempted by the ploy," says Brett Myroff, CEO of regional Sophos distributor, Sophos South Africa. "This is just another attempt by hackers to gain access to confidential information. If you receive emails like this, exercise extreme caution and don't ever run unsolicited attachments."
Sophos detects the malicious Trojan as Troj/Agent-HNY.
