Troj/BeastDo-Y is a backdoor Trojan for the Windows platform.
When first run Troj/BeastDo-Y copies itself to:
<Windows system folder>\expl0rer.exe
<Windows system folder>\sp00lsv.exe
and creates the following files:
<Windows system folder>\mydll.dll (also detected as Troj/BeastDo-Y)
<Windows system folder>\pztrain.exe (clean)
<Windows system folder>\win32log.dat (clean)
The following registry entry is created to run expl0rer.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
EXPLORER
EXPL0RER.EXE
Troj/BeastDo-Y connects to a preconfigured IP address and awaits further instructions.
