Re: echo scans

Seems like they scanned in an effort to find an easily rootable service. DNS, NFS, etc, etc... As for the echo stuff 
they could've been searchin for something like an outlet for DoS's eg.
echo | chargen or some type of other bouncy like DoS.

As for the scan starting at 2443, thats PCCSF (powerclient central storage facility) which I have never seen on any 
security related list. Same with ports 516 (videotex) ,511 (passgo) ,633 (servstat), etc etc... They could've just 
scanned in a funky order maybe with thoughts that if it seemed funky it would throw off an admin? (sounds crackheadish 
I know...)


2443, 53, 516, 511, 162, 111, 109

633, 987, 171, 241, 848, 278, 700, 119, 899, 317

196, 909, 129, 128, 883, 840, 904, 553, 177, 679, 803, 106, 418, 340,
126, 635, 373, 834

90, 959, 545, 217, 187, 1011, 967, 677, 19, 630, 858, 758

538, 949, 818, 642, 711

905, 873, 562, 317, 764, 637, 280, 378

881, 191, 688

then the 4 minute scan on tcp/udp port 7.

Regards.


FYI here is a link for a listing of port numbers which I'm praying people will save and do some little homework on... 
e.g.: Someone port scans you on say... 1706 ... Then look up on Security Focus for Jetform or whatever program 'should' 
be running on the defined port.

"maybe someone some where will appreciate it"
