New Worm/Virus April 8th

[Polazzo Justin]

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).=20

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

What's the propagation method? Is it through email?
