Description

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Indication of Infection

Macro warning when opening infected document on non-infected system, and macro warning is enabled before hand. Files are deleted from the STARTUP folder in Office97/2000.

If the current day is March 5, August 8 or December 22, and MS Office Assistant (MSA) is installed, this message will be displayed using the MSA:

"ReYoKh Team Labs mengucapkan"
"Selamat Ulang Tahun !!!"
"untuk [Name] bahagia selalu"

In the above message, [Name] can be one of three words: "REZA", "YOMBI" or "NELIS".

Methods of Infection

This virus hooks Word event handlers in an effort to maximize the chance of running its code. The following methods can invoke the macro routines: opening, closing, saving or creating a document.

If the code is allowed to run, this virus first writes a temporary file in the STARTUP folder for Office named "EcHa". This temp file is then used to transfer code between infected file and new host document. The temp file is deleted along with any files which may be stored in the STARTUP folder.

SCANPM /ADL /CLEAN /ALL

Additional Windows ME/XP removal considerations


Users should not trust file icons, particularly when receiving files from others via P2P clients, IRC, email or other mediums where users can share files.

AVERT Recommended Updates :

* Office2000 Updates

* Malformed Word Document Could Enable Macro to Run Automatically (Information/Patch )

* scriptlet.typelib/Eyedog vulnerability patch

* Outlook as an email attachment security update

* Exchange 5.5 post SP3 Information Store Patch 5.5.2652.42 - this patch corrects detection issues with GroupShield

It is very common for macro viruses to disable options within Office applications for example in Word, the macro protection warning commonly is disabled. After cleaning macro viruses, ensure that your previously set options are again enabled.
