Note From Lampung (Virus Film_Lampung.EXE)

HI All

After visiting lampung for two days then I finnally can cope with the mind games of our computer virus infection, the reverse engineering of the virus it self take me 1 whole day to discover of how it works and what the effect it might cause to the system.

eventhough my risk assessment of this viru is low however it takes a lot of effort to break the mind games, well i would say this is NOT the easiest as apparently my SYmantec end-point picking up some Hacktool on my machine. is it coming from film_lampung??? or have I been hacked??

Indications of Infection

Hides and replace your office files to folder form with .exe extension ( “file_name”.exe)
It hides “Mem Usage” on your windows Task Manager and on some case its disable most of Windows Task Manager. It also consumes a lot of memory thus your computer become slow (as all Trojan would do).

Method of Infection

Viruses are self-replicating. They are often spread by a network or by transmission to a removable medium such as a removable disk, writable CD, or USB drive. Viruses may also spread by infecting files on a network file system or a file system that is shared by another computer.

Removal Instructions

1. Go to Start > RUN > Msconfig then Untick MB’ process

2. Install The repair.inf you can should see the hidden files and folder now (download the file by clicking the hyperlink then right click install)

3. Go to “Folder Option” > “View Tab” > Tick “Show Hidden Files and Folders”

4. Delete Mb’.exe on C:\windows\system32\MB’.exe

5. To prevent the virus from being re-active after re-boot kill the startup process on my case I have 2 startup process.

C:\Document and Settings\All Users\Start Menu\Programs\Startup\msoffice.exe
C:\Document and Settings\windows XP\Start Menu\Programs\startup\ Msoffice.exe


for this step you can use “killvb” from Yohanes Nugroho ( thanks Mr. Yohanes

6. Delete these files PCMAV.exe, New Folder.exe, Film_lampung.exe (these files has 172 KB of size) its commonly to be located on each drives of your machine
7. And also delete SuppMB.BAT & RegMB.reg.

8. This Virus will replace your file with “your filename”.exe (in the form of folder) and they all have the same file size of 104KB,however the Virus has hidden your original file which after the removal you could see them.
