A new Malware/Trojan (Scareware/Ransomware) has been identified that attempts to scare users by a series of messages that try to imitate the Microsoft's activation procedure. On a compromised system a message will appear saying the copy of Windows is locked (Windows license locked!).

trojan_generic_kdv_153863 Windows license locked!

The Trojan claims that "you should complete activation" and provides several phones numbers.


The numbers listed are:

  • 002392216368
  • 002392216469
  • 004525970180
  • 00261221000181
  • 00261221000183
  • 00881935211841

While these numbers may look like generic service numbers, they aren't. They go to various countries, São Tomé and Principe (239), Denmark (45), Madagascar (261) and Globalstar Mobile Satellite Service (8819). The Trojan claims the call are "free of charge" but they aren't. In fact the Trojan author will earn money from the call via a technique known as short stopping. This method involves rogue phone operators who route the expensive calls to cheaper countries.

After several minutes on the phone the caller is given this unlock code: 1351236. The unlock code appears to be the same number on every call.

Operations Director, Ian Chilvers, said "It's a pretty clever bit of social engineering and some victims may never even realise that they've even been scammed."

F-Secure have named the Trojan as Trojan.Generic.KDV.153863.
