I've been seeing a handful of emails that look a lot like Sobig.F (same or similar subjects, same body), but do not contain the attachment. Does anyone know what's going on? I'm thinking that either: 1) Someone is using similar messages to probe email accounts 2) A new version of Sobig is out (perhaps probing accounts first, then sending the payload later?) 3) Something is broken with Sobig.F, causing it to fail to attach from time to time. I have several copies available if anyone is interested. I haven't dissected the headers, etc. to look for similarities or differences with Sobig.F messages. --Rich _________________________________________________________ Rich Puhek ETN Systems Inc. 2125 1st Ave East Hibbing MN 55746 tel: 218.262.1130 email: rpuhekat_private _________________________________________________________ --------------------------------------------------------------------------- Attend Black Hat Briefings & Training Federal, September 29-30 (Training), October 1-2 (Briefings) in Tysons Corner, VA; the world's premier technical IT security event.
