A security professional fights back against tech support scammers

I guess Matt Weeks is as sick as I am of tech support scammers, because he developed a way to fight back, in the form of a Metasploit module that exploits a software defect in the AMMYY remote access tool that these scammers sometimes use. Metasploit is a tool that penetration testers use to demonstrate–with permission–how hackable a computer network is. In this case, the would-be victim is penetration testing someone without permission. Run the module when the scammer connects to the would-be victim, and he or she gets a command prompt on the criminal’s PC. At that point, the would-be victim can break their computer, perhaps by deleting critical files, corrupting the Windows registry, or something else. Anything you can do from a command prompt would be possible at that point.

I’m anything but heartbroken that this threat exists, although I’m not going to do this myself. Let me explain. Read more

This “Computer Maintenance Department” sure doesn’t know much about computer maintenance

“Peggy” from “Computer Maintenance Department” (1-645-781-2458 on my caller ID) called again. Lots of people are aware of these phone calls. They call, make vague claims about receiving a report that your computer is running slow and giving you errors, and are very careful not to say who they are or who they work for. Usually I just do whatever I can to get them off the phone.

But after having lunch with some other computer security professionals last week, a couple of them talked me into finding out how these guys operate. So I fired up a PC that turned out to have a real, legitimate issue. After resolving that issue myself, I turned the caller loose on my semi-functional PC so I could see what these scammers actually do. He had me connect to Teamviewer.com and run their remote access software. I followed his instructions, watched him connect, then slyly unplugged my network cable.

When my network connection dropped, “Peggy” quickly transferred me to a “senior technician” who used the name “Roy.” Read more
