For the past 2 weeks or so, we were averaging 1,200 probes per hour. As of 8 or so this morning, we started averaging > 25,000 per hour! I've noticed that at the same time, we started getting probes from our provider's space (uniquely 23 addresses there), but not our own. Until this morning, we had *0* probes from inside our provider's space. Maybe this is the next round kicking off, looking for things to infect locally before searching the world again.
Simular here, most probes so far are coming from Speakeasy DSL IPs to my Speakeasy DSL servers. Haven't checked the others yet. So far about 20k probes.

NT worm probes this morning? We're seeing about 8000/second, starting around 9:15 Eastern time, to and from a wide variety of addresses. Is CodeRed or one of its relatives scheduled to start sweeping again today? We've never seen this level of traffic related to the NT worms. Even though we don't run any NT at all, we still have to suffer :(First ones appeared today, and so far I see 17650 attempts on just one of my servers. We don't run any Microsoft stuff either, but that doesn't keep our servers from getting hammered... ----------------------------------------------------------------- Daniel Senie dts () senie com Amaranth Networks Inc. http://www.amaranth.com
