[nsp-sec] Korea telecom/KORNET?

[Michael Sinatra]

Hi,

The host listed below has been engaging in very aggressive SSH
brute-force attacks on UC Berkeley's address space.  What makes this
host different from the others is that:

1. It has been going on for *weeks* and is still going on.

2. abuse at kornet.net does not appear to be responding to request(s) to
make it stop.

AS      | IP               | Info                 | AS Name
4766    | 125.152.96.154   | 26-Mar-2009 00:42:21 | KIXS-AS-KR Korea Telecom

Is there anyone from Korea Telecom with clue that can put an end to this?

thx,
michael
