Security Incidents: Odd MS-Sql scans.

["larosa, vjay" <larosa_vjay () emc com>]

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?

Thanks!
