I work at a large ISP in Canada and just a few hours ago we've experienced a massive increase in spam volume. The volume is so high it's bordering on being a denial of service attack. Does anyone know if there's a worm out in the wild currently doing this? I've confirmed with some of my collegues that other ISPs are also experiencing this. I'm interested in finding specific netblocks but the spam seems to be coming from everywhere.
I'd say you're seeing the first wave of what appears to be a new worm. Earlier this evening I received about 20 copies of the same message (same subject, same body, different senders) which was titled, "Osama bin Laden found!" and listed a URL (http://220.95.231.54/pics/). Being naturally curious (and even more naturally paranoid), I went to the URL...but not with my browser. What I snagged was an obfuscated Javascript page which -- from what I could decipher at a glance -- was some kind of spam pitch for cheap prescription drugs. I didn't bother looking for a malicious payload after that. So what we have here could be a worm that spews spam. This sort of thing will pretty much render the idea of blackholing netblocks useless now, since unpatched Windows system are everywhere. That's my take. I look forward to hearing about what others have seen land in their inboxes. - -Jay ( ( _______ )) )) .--"There's always time for a good cup of coffee."--. >====<--. C|~~|C|~~| )>------ Jay D.
