RE: [AppSec-research] New Worm/Virus April 8th
I know that it is bad form to reply to your own post, but here it goes anyway:
There is an accompanying file called nwiz.exe in the \Winnt folder.
The worm/virus writes the following to an infected machines hosts file
127.0.0.1 www.symantec.com
127.0.0.1 securityresponse.symantec.com
127.0.0.1 symantec.com

127.0.0.1 rads.mcafee.com
127.0.0.1 trendmicro.com
127.0.0.1 www.trendmicro.com
I also noticed that the fully patched and av protected machines that were
infected had lame administrator passwords (and the account "Administrator" had
not been renamed), which is the most likely point of compromise.
All in all not something to worry about unless you dont have MS03-039 or use
123456 as your admin password :)

Subject: [AppSec-research] New Worm/Virus April 8th
Mail from "Polazzo Justin" <Justin.Polazzo@xxxxxxxxxxxxxxxxxxxxx>
Concerning the new worm type infection spreading around today (6:15am EST)
the file is called ndemon.exe (.99k) and it puts itself into c:\winnt and
c:winnt\system32. Registry entries HKLM\Software|Microsoft|CurrentVersion\Run
and HKLM\Software|Microsoft|CurrentVersion\RunServices (Think it creates that
one).
At first look:
it then tries to propagate itself via MS ports 135, and 139 VIA known flaws and
password guessing. It also listens for other infected machines on port 1025 and
scans for MS IIS boxes on port 80 (to try known exploits as well)
The infected machines were win2k SP4 (fully Patched) Running Symantec AV v8.6
Just a heads up
