"A new breed of pop-up ads is appearing mysteriously on Microsoft Windows users' computers. The so-called "Messenger spams" have security experts and system administrators scratching their heads -- and recipients fuming.Sounds familiar.
I tweaked our firewall rules to explicitly block 135-139 and we've had 241 udp drops and 3 tcp drops in the last minute or so. Nice to see we're being probed.
