Text Messaging Con Users into Downloading a Trojan
People are now being conned into downloading a Trojan through text messaging. People are receiving text messages thanking them for signing up with a fictitious online dating service. It also tells them that they will receive a $2 fee per day to their cell phone for the service. To cancel the service, the user must go to a website where they are prompted to download a variant of the Dumador Trojan bot. The site does not attempt to exploit any vulnerabilities; instead, the attacker provides instructions to the user on how to bypass the Internet Explorer security warning prompt. This works well on the less PC savy indivuals. The Trojan allows the computer to be remotely controlled as itreceives remote commands by making GET requests to two different web addresses. It also prevents users from accessing certain webpages, particularly antivirus software websites. As always, be wary and check into any sites that prompt you to download anything.
