Hi there!

We've got some problems with the blaster worm.
There are several Class-C networks which are connected by a router.

The LAN ist build like this.

Location 1 192.168.100.x 255.255.255.0
Location 2 192.168.120.x 255.255.255.0
Location 3 192.168.140.x 255.255.255.0

and so on...

In every location there is a router (192.168.x.250) which is connected to
the HQ via a 128kbit permanent connection.

One of these class-C networks was infected by the blaster worm.
Sad but true, there were no patched machines and no anti-virus-software.

If Location 1 is the infected LAN, is the worm able to distribute itself to
Location 2 and 3?


Thanks for you help!

Kind regards

Axel

Click to expand...

if the machines at location 2 and/or 3 are directly addressable from
location 1 then yes it is possible for the worm to distribute itself to
location 2 and/or 3...
