The size of worm is 50,634 bytes,Kaspersky detects it as Email-Worm.Win32.Banwarum.l,Trend Micro detects it as WORM_NUWAR.EL.

Upon execution, this worm drops a copy of itself as “\%system%\ALSYS.EXE”. It also drops a randomly named file, which is the file of Storm Worm, in the folder where this worm is initially executed.

It creates the following registry entries:


HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
agent = "%System%\alsys.exe"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
agent = "%System%\alsys.exe"

This worm searches for .EXE and .SCR files on the affected system where it inserts a code that programs the target files to automatically execute a copy of this worm that bears the file name {Random}.T.

An hour ago,we received a new variant.The size is 50,629 bytes,Kaspersky can’t detect it now.
