Re: port 22 scans + 53 scans

From: Steven S <stevensl () corp earthlink net>
Date: Sat, 6 Oct 2001 15:53:28 -0400 (EDT)

I got 1 probe from 131.152.102.64 @ 13:57 EDT today to port 22

then a flood (81 @ present) of port 53 connection attempts within about 2
minute time span, nothing before nothing after (so far)

notice that i got two port 53 attempts in a 12+ hour period then blam!

spoofed sources?
i was forwarding these packets to from my gateway/router to another host
for analysis (this the F at the end stands for Forward) but the host is
currently down for upgrading.

On Thursday (Oct 4), we have detected four sweeps, looking for open

The traits of all those sweeps were very similar:

- the source port of all probes was 22
- all probes within one sweep had the same IP ID (*)
- lost/filtered probes were not retried
- the sweeps were pretty fast, hundreds of addresses in few seconds
- no actual i/o was done

(*) With 1 exception that had a TTL different from other logged probes
in the sweep as well.

Is there any kind of SSH worm out there?!
