More Information
W32/Stucco-B is a worm for the Windows platform.
When first run W32/Stucco-B copies itself to <System>\kavo.exe and creates the following files:
<Temp>\n4chbe.dll
<Temp>\v4ij7fde.sys
<System>\kavo0.dll
The file kavo0.dll is detected as Troj/Lineag-Gen and the file v4ij7fde.sys is detected as Mal/RootKit-A.
The following registry entry is created to run kavo.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
kava
<System>\kavo.exe
W32/Stucco-B spreads by copying itself with the hidden filename ntdelect.com to network shares and removable media. The file autorun.inf is also created so that W32/Stucco-B is automatically executed. This file is detected as Mal/AutoInf-A.
