I checked our logs and it seems likve we've had 10-20 different ip addresses scan for tcp/111, tcp/21, or tcp/27374 Whats the standard approach? Just leave it alone since it doesn't affect your network or contact the people the scan came from? One of the sites resolve to mailgate.lostinspace-hub.com.. that sounds like a box they don't want rooted.. so I will probably email them.. but what about the other? There are misc. @home/dialup addresses, etc. Thanks, Magnus Ullberg Network Coordinator Area Bancshares Corporation Networking Department 230 Frederica St. Owensboro, KY 42301 -----Original Message----- From: Steve Clement [SMTP:steve () ALDIGITAL CO UK] Sent: Tuesday, January 16, 2001 7:39 AM To: INCIDENTS () SECURITYFOCUS COM Subject: Re: FTP and RPC based worms [was anyone else ...] Russell Fulton wrote: > > On Mon, 15 Jan 2001 14:40:16 +0200 Mihai Moldovanu <mihaim () PROFM RO> > wrote: > > All fairly standard stuff except that the whole process took under 2 > minutes from initial probe to launching the scanner. > > I conclude that what we have here is a worm spreading via ftp. > > I have port scanned the compromised system and it is listening on port > 27374, the same as the one on 194.163.254.235 where it got its tools > from.
