We don't have any reports of significant increases in malicious traffic (yet) but just as a reminder to sysadmins around the world many colleges and universities are welcoming back their students this weekend and next weekend.  Due to the world-wide spread of malware through the Storm Worm over the past several months we expect that all of those infected laptops will have a field day once they connect to the university networks.

As reported in a diary yesterday, the Skype VoIP service has been down for well over a day.  Many of our readers report that they still can't get their clients to connect, while others say it's working fine.  According to Skype, all is well and everybody should be happy.

So what is really going on?  Was it just a "software problem" as Skype says?  Here are some ideas to consider:

Unless something "new" comes up, we ask that you keep an eye on Skype's heartbeat blog for further unfolding details.  (Thanks, Roland, for the links!)

UPDATE:
Ronaldo reminded us of the Snort Skype Preprocessor  posted a few days ago.  A preprocessor that detects/blocks Skype....hmmm....
