W32/Vanebot-M may spread with the filename redworld.exe, redworld2.exe or <random numbers>_redworld2.exe.
When first run W32/Vanebot-M copies itself to <Windows system folder>\dllcache\dragonage.exe.
The file dragonage.exe is registered as a new system driver service named "Dragon Age - Bioware", with a display name of "Dragon Age - Bioware" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\Dragon Age - Bioware\
W32/Vanebot-M sets the following registry entries, disabling the automatic startup of other software:
HKLM\SYSTEM\CurrentControlSet\Services\wuauserv
Start
4
HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess
Start
4
Note: disabling autostart for the SharedAccess service deactivates the Microsoft Internet Connection Firewall (ICF).
Registry entries are set as follows:
HKLM\SOFTWARE\Microsoft\Ole
EnableDCOM
N
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
lmcompatibilitylevel

HKLM\SYSTEM\CurrentControlSet\Control\Lsa
