W32.Mybabypic.Worm is a worm that mails itself to all address in the Microsoft Outlook address book. SARC has received very few submissions of this worm.
When W32.Mybabypic.Worm is executed, it mails itself to all address in the Microsoft Outlook address book. A very offensive two-frame animation of a baby is also shown.
The email message sent out contains the following subject line:
My baby pic !!!
and contains the following text in its message body:
Its my animated baby picture !!
The file attached has the name:
mybabypic.exe
and has the icon picture:
The W32.Mybabypic.Worm does the following:
It creates duplicate copies of itself in the \Windows\System folder with the following names:
On certain dates and times, the worm may do the following.
It goes to the website
http: //www.myhomepage.com
using one of the strings below as the form parameter:
FROM BUGGER
HAPPY VALENTINES DAY FROM BUGGER
HAPPY HALLOWEEN FROM BUGGER
It searches for files on your local drive and on all mapped drives. Depending on the file extension, the worm does the following things:
For VBS and VBE files, the worm permanently corrupts them.
For C, CPP, CSS, H, HTA, JS, JSE, PAS, PBL, SCT, WSH files, the worm uses the filename with the extension replaced to .EXE, and creates a duplicate copy of itself using this new filename, and deletes the original file. For example, if you have a file called SAMPLE.HTA, the worm creates a duplicate copy of itself with the name SAMPLE.EXE, and the worm will delete the file SAMPLE.HTA.
For JPG and JPEG files, the worm will simply attach the EXE extension instead of replacing the original file extension. Thus in the example mentioned above, if say the file turned out to be SAMPLE.JPG instead, the duplicate copy of the worm will have the filename SAMPLE.JPG.EXE, and then SAMPLE.JPG will be deleted.
For MP2, MP3, and M3U files, the worm will grab the filename, add an EXE extension to it, and will use this new filename for its duplicate copy. As for the original file, instead of being deleted, its file attribute is set to hidden. Thus if we have a file called SAMPLE.MP3, the worm will create a duplicate copy of itself with the filename SAMPLE.MP3.EXE, and it will set the file attributes of SAMPLE.MP3 to hidden.
The worm program may also toggle the NumLock, CapsLock, and ScrollLock keys.
Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":
Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services (for example, all Windows-based computers should have the current Service Pack installed.). Additionally, please apply any security updates that are mentioned in this writeup, in trusted Security Bulletins, or on vendor Web sites.
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
To remove this worm, delete the infected files, and undo the changes that the worm made to the registry.
To remove the worm:
Run LiveUpdate to make sure that you have the most recent virus definitions.
Start Norton AntiVirus (NAV), and run a full system scan, making sure that NAV is set to scan all files.
Delete any files detected as W32.Mybabypic.Worm.
To edit the registry:
CAUTION: We strongly recommend that you back up the system registry before making any changes. Incorrect changes to the registry could result in permanent data loss or corrupted files. Please make sure you modify only the keys specified. Please see the document How to back up the Windows registry before proceeding.
Click Start, and click Run. The Run dialog box appears.
Type regedit and then click OK. The Registry Editor opens.
