Stopping NetBIOS Spam?

Posted by Cliff on from the nothing-is-sacred dept.

MoonFacedAssassin asks: "I woke up this morning to find that my computer had a Windows messaging pop-up window with an advertisement about getting diplomas and degrees. I was quite shocked to find that my Bellsouth DSL IP address had been spammed. Has this happened to anyone else? Other than closing off the port which this can come through, are there any other ways to block this spam? And, how responsible is Bellsouth (or any ISP for that matter) in handling issues like this?"

    Most decent DSL/CABLE Modem providers block the netbios ports these days...thats just sad that they have those ports open and avialable for traffic on thier network.

    Hint: Get a linksys router and those ports will no longer be available for spam...

    Hint2: Don't leave windows machine hanging on the wire like that unless they are memebers of NT domain. It will stepup the security of the Netbios connections.

    Hint3: Not ever leave an improperly secured NT machine hanging on the wire like that....

    Hint4: see hint 1

    I don't know about popping a message, but you could have fun with Slap:

    Slap - If you're like me you run firewall software that tells you when someone tries to access your system. Sometimes I respond with a few packets of my own just to let them know that I am paying attention. I wrote Slap to make responding to these access attempts easier and more entertaining. Just enter the IP address of the person you wish to slap and click on the Slap button. The program will attempt to access all the ports in the list and send them a packet with a personal message. (The default message is 'Leave Me Alone!') Slap integrates with Black Ice and Zone Alarm and can use information received from these software firewalls to "Auto Slap" intruders and add their attacks to your list of responses. --Here is a cool Wav file to use with this.
