Characteristics

AVERT received copy of this file for analysis in the pre-dawn hours of December 10th. This worm was written in Visual Basic 5.0 and it is a minor variant to the earlier discovered W32/Mypics.worm. This worm also has a reliance on the library file MSVBVM50.DLL. Without this file, the program will error. This file will copy itself to the root drive of the local machine as "Icq.exe" and also "ICQ_Greetings.exe", and register itself to run from the registry at system startup with multiple registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run Icq99b="C:\Icq.exe"

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Windows\CurrentVersion RegisteredOrganization="2034 Langley Ct. Holloman Afb, NM 88330"

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Windows\CurrentVersion RegisteredOwner="Mike Carmody"

HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Windows\Run Icq99b="C:\Icq.exe" It does not matter if the system is Windows 9x or Windows NT, the keys are created or modified anyway.

While the file runs as a task in memory, it is performing two functions. One function is to spread via an email routine while the attempts to delete files in specific folders. Another function to format drives was not operational and could not be verified in AVERT testing.

This worm uses mass email for distribution, if executed. It appears to use code similar to W97M/Melissa virus to distribute itself using MS Outlook to the first 50 email recipients, however emails created by this worm contain the message "Season's Greetings" (Office97 registered user name) and attach itself as a file "ICQ_Greetings.exe" with a size of 27,648 bytes; users receiving this worm may also receive a file named "Passion.exe" of the same size. The icon of the attached file matches the same icon used to load ICQ application and appears as a multi-colored flower (below).

Symptoms

Existence of this file on the local system - modifications to the system registry as mentioned above - mass mailings as mentioned above, file deletions as mentioned above.

Method of Infection

Running the executable will directly copy itself and run the mass mailing routine.

Removal

All Users :
Script,Batch,Macro and non memory-resident:
Use current engine and DAT files for detection and removal.

PE,Trojan,Internet Worm and memory resident :
Use specified engine and DAT files for detection. To remove, boot to MS-DOS mode or use a boot diskette and use the command line scanner:

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

Additionally, Network Administrators can configure this update using an available tool - visit this link for more information .

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.

All Information

Overview -

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.
