To this date the only persons affected by the attacks are mobile phone owners from USA and Canada that can receive a spam message informing them that they are the proud possessors of a $2 per day subscription to a nonexistent dating website. The security company MicroWorld Technologies has issued a warning reveling that if followed accordingly, the message's instructions will actually open the way for the Backdoor Trojan Dumador.bc and not offer a way to unregister the fictive subscription.

The Trojan is a type of malware known as keylogger. Once it has compromised a machine it will block access to the sites of online security companies by modifying the Windows HOSTS file and will open the dual TCP ports communicating with websites controlled by the attacker. Dumador.bc also captures information relating to accounts of online banking services and user credit card data. Furthermore, the Trojan will pave the way for transforming the compromised computer in an element of a botnet, such zombie networks being used for DoS attacks, hijacking of SMPT mail servers and launching spam campaigns.

"Our users updating their software have no reason to worry as we've been providing protection for this Trojan ever since Apr 11, 2005," informs Sulabh Mahant, Security analyst, MicroWorld Technologies. "What's intriguing here is the bi-layered mode of proliferation with truly sophisticated Social Engineering. The thought of draining two dollars per day is good enough to make one panic. And the trick is all about inducing that state of mind where you lose senses and readily follow what the fraudster tells you to do."
