I-Worm.Scrambler

Description I-Worm.Scrambler

This is an Internet worm virus that spreads in infected e-mails, sending its copies to IRC channels, and infecting Windows EXE files on a local machine. The worm itself is a Windows executable file about 70K in length written in Microsoft Visual C++.
When an infected file is executed, the virus creates its "dropper" (a file with pure virus code) in the Windows system directory. This file has a random 5-letter name, for example: HIJDE.EXE. This file is used later to send virus copies to Internet and IRC channels.
The virus then scans the Windows directory, looks for Windows executable .EXE files and infects them by writing the virus code to the top of the file. The virus avoids infecting files with names that begin with any of the following letters: E, P, R, T, W. The virus then infects all EXE files in the C:MIRCDOWNLOAD directory, if it exists in the system.
Next, the virus infects the mIRC client to send its copies to IRC channels as well as MS Outlook to spread with e-mail messages.
To infect the mIRC client, the virus tries to create (overwrite) a SCRIPT.INI file in standard mIRC directories on all drives from C: to F:. The infected file names appears as follows:
mircscript.ini
PROGRA~1mircscript.ini
The worm writes a short script to there that sends its "dropper" to each user that enters the infected channel.
The virus creates the SCRAMBLER.VBS VisualBasic in the Windows system directory and writes to there a script program that connects to MS Outlook and sends e-mail messages to the first 90 users from the MS Outlook address book. The messages have an infected attachment (virus "dropper"); the subject is "Check this out, it's funny!"; and the message body is empty. The virus then spawns that script, and spreads to the Internet as a result.
The virus then creates the WINSTART.BAT file in the Windows directory and writes two commands to there that clear the screen and display the following message when that file is executed:
Today..
I'm going to scramble your mind..
The virus also creates the SCRAM.SYS file and saves the text to there:
Scrambler
by Gigabyte
The virus also scans drives for MP3 files and corrupts them.

I-Worm.ScrapWorm (a.k.a. Stages)

Description I-Worm.ScrapWorm (a.k.a. Stages)

This is the Internet worm that was found in the wild in the middle of June 2000. The worm spreads via e-mail by sending infected messages from affected computers. While spreading, the worm uses MS Outlook and sends itself to addresses that are randomly selected from MS Outlook Address Book.
The worm is written in the scripting language "Visual Basic Script" (VBS). It works only on computers on which the Windows Scripting Host (WSH) is installed. In Windows 98 and Windows 2000, WHS is installed by default. To spread itself, the worm accesses MS Outlook and uses its functions and address lists. That is available in Outlook 98/2000 only, so the worm is able to spread only in case one of these MS Oulook versions is installed.
When run, the worm sends its copies via e-mail, installs itself into the system and copies itself to network drives. The worm also has the ability to spread through mIRC channels.
The worm contains a "copyright" string:
'MIRC/NETWORK/OUTLOOK/PIRCH.ShellScrapWorm by SimpleSimon / Zulu
Spreading
The worm arrives to a computer as an e-mail message with an attached SHS file that is a scrap package with a worm inside. The message subject may be different, and it is combined from three sets of strings:
"Fw: ", ""
"Life stages", "Funny", "Jokes"
" text", ""
Examples:
Fw: Jokes
Life stages
Funny text
The message body may be empty or one of these is present:
> The male and female stages of life.
> The male and female stages of life. Bye.
The message has the attached file "LIFE_STAGES.TXT.SHS" that contain worm inside.
Depending on system settings, the real extension of the attached file (".SHS") may not be shown. In this case, the filename of the attached file is displayed as "LIFE_STAGES.TXT".
Being activated by a user (by double-clicking on the attached file), the scrap package (SHS-file) activates its content. As soon as the attached file contains the VBS file inside, containing a Visual Basic Script program, this file is executed and the worm's script gains control.
The worm creates a text file in the temporary directory and displays it using the text editor. The file content is:
- The male stages of life:

Age. Seduction lines.
17 My parents are away for the weekend.
25 My girlfriend is away for the weekend.
35 My fiancee is away for the weekend.
48 My wife is away for the weekend.
66 My second wife is dead.

Age. Favorite sport.
17 Sex.
25 Sex.
35 Sex.
48 Sex.
66 Napping.

Age. Definiton of a successful date.
17 Tongue.
25 Breakfast.
35 She didn't set back my therapy.
48 I didn't have to meet her kids.
66 Got home alive.

- The female stages of life:

Age. Favourite fantasy.
17 Tall, dark and hansome.
25 Tall, dark and hansome with money.
35 Tall, dark and hansome with money and a brain.
48 A man with hair.
66 A man.

Age. Ideal date.
17 He offers to pay.
25 He pays.
35 He cooks breakfast next morning.
48 He cooks breakfast next morning for the kids.
66 He can chew his breakfast.
After that, the worm opens MS Outlook, gains access to the Address Book, obtains a hundred random addresses from each address list and sends messages with its attached copy to all of them. The message subject, body and attached file name are the same as the abovementioned.
The worm also installs itself into the system. It creates its copies in Windows directories with the names:
in Windows directory: LIFE_STAGES.TXT.SHS
in Windows system directory: MSINFO16.TLB
in Recicle bin: MSRCYCLD.DAT
Then the worm creates its copies with random names in root directories of all local hard drives and also in the "Programs" and "My Documents" folders. If a Windows startup folder exists on the network drive, the worm copies itself there.
The worm also drops files:
in the Windows system directory: SCANREG.VBS
- this file worm registers in the system registry in the auto-run section to be executed upon each Windows startup:
HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServicesScanReg = "WSCRIPT.EXE SCANREG.VBS"
- the worm creates a copy of this file in the Recycle bin:
RCYCLDBN.DAT
in the Windows directory: DBINDEX.VBS
- this file worm registers in the system registry in the ICQ section to be executed upon each ICQ startup:
HKEY_USERS.DEFAULTSoftwareMirabilisICQAgentAppsICQEnable = "Yes"
HKEY_USERS.DEFAULTSoftwareMirabilisICQAgentAppsICQParameters = "C:RECYCLEDDBINDEX.VBS"
HKEY_USERS.DEFAULTSoftwareMirabilisICQAgentAppsICQPath = "WSCRIPT.EXE"
HKEY_USERS.DEFAULTSoftwareMirabilisICQAgentAppsICQStartup = "C:WINDOWS"
- the worm creates copy of this file in Windows system directory:
VBASET.OLB
As a result, the worm is re-activated each time Windows boots up or ICQ starts.
Spreading to IRC channels
The worm scans local drives and looks for an MIRC.INI file. In case this file is found in a subdirectory, the worm drops a SOUND32B.DLL file there. This file contains mIRC instructions that send a worm copy (LIFE_STAGES.TXT.SHS file) to all users that join the infected IRC channel. In MIRC.INI, the file worm adds the reference to SOUND32B.DLL into the "rfiles" section.
Other
The worm moves the REGEDIT.EXE program into the Recycle bin with the name RECYCLED.VXD.
