Hello, This morning while reviewing my IDS logs I found about 1,000 events all originating from one source IP (64.166.152.138) incrementally scanning one of my subnets for port 1433. These scans were odd to me because the packet payload was cko (Q traffic payload) the flags were AR, Sequence number, Acknowledgment number, and TCP window size numbers were all 0, and the TTL is always between 1-2 (this might be because the stream4 TTL evasion flagged these packets). Is anybody else seeing anything like this?
don't know about the specific packets, but this computer has been attacking the world since jun 27th: http://www.mynetwatchman.com/LID.asp?IID=35323835 looks like 24 larts have been sent off to pacbell starting on july 1st Maybe if someone at pacbell can disconnect this computer till they get rid of their worm. -- Michael Scheidell SECNAP Network Security, LLC Main: 561-368-9561 / www.secnap.net Looking for a career in Internet security? http://www.secnap.net/employment/ --------------------------------------------------------------------------- FREE Whitepaper: Better Management for Network Security Looking for a better way to manage your IP security?
