Summary: Worm. A program that is primarily replicating on networks or removable drives.
Dynamic Analysis
Payload
Behaviour | Description |
---|---|
WormAutorun | A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Worm's file once a user opens a drive's folder in Windows Explorer. |
Process activity
The Worm creates the following process(es):
vbc.exe:1600
%original file name%.exe:1584
reg.exe:1260
reg.exe:1656

reg.exe:660
The Worm injects its code into the following process(es):
vbc.exe:1324
xbox freezer 0.1.exe:1912
File activity
The process vbc.exe:1600 makes changes in the file system.
The Worm creates and/or writes to the following file(s):
