While I was at work yesterday, Shannon received another little bit of Windows Messenger spam on my desktop, demonstrating that I had not yet banished this annoyance from my home network. Luckily, there’s been even more progress in tracking down exactly how the messages are sent, and it turns out that I left one last itty bitty port open (UDP port 135).

Before adding a rule banning traffic on that port to my router, I checked the access list logs, and saw that more than 1,500 attempts had been made to send packets over the previously-banned ports. Is Windows Messenger spam becoming this popular?


You can do more than just block it, you can track them right to their IP address!
