Payload

Behaviour	Description
WormAutorun	A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Worm's file once a user opens a drive's folder in Windows Explorer.

Process activity

The Worm creates the following process(es):

%original file name%.exe:1332
csc.exe:348
cvtres.exe:844

The Worm injects its code into the following process(es):

iexplore.exe:948

Mutexes

The following mutexes were created/opened:No objects were found.

File activity

The process %original file name%.exe:1332 makes changes in the file system.

The Worm creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.cmdline (238 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.out (305 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.0.cs (196 bytes)
%Documents and Settings%\%current user%\Application Data\IDD2QN3SGQ\IDD2QN3SGQ.exe (4185 bytes)

The Worm deletes the following file(s):

%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.cmdline (0 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.err (0 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.out (0 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.0.cs (0 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.dll (0 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.tmp (0 bytes)

The process csc.exe:348 makes changes in the file system.

The Worm creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Local Settings\Temp\CSC1.tmp (652 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.out (396 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\soveiyi6.dll (3110 bytes)

The Worm deletes the following file(s):

%Documents and Settings%\%current user%\Local Settings\Temp\CSC1.tmp (0 bytes)
%Documents and Settings%\%current user%\Local Settings\Temp\RES2.tmp (0 bytes)

The process cvtres.exe:844 makes changes in the file system.

The Worm creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Local Settings\Temp\RES2.tmp (2912 bytes)

Registry activity

The process %original file name%.exe:1332 makes changes in the system registry.

The Worm creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "72 08 D9 75 60 06 E3 8B 32 15 08 BB 82 43 87 45"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"AppData" = "%Documents and Settings%\%current user%\Application Data"

"Cache" = "%Documents and Settings%\%current user%\Local Settings\Temporary Internet Files"

[HKCU\Environment]
"SEE_MASK_NOZONECHECKS" = "1"

To automatically run itself each time Windows is booted, the Worm adds the following link to its file to the system registry autorun key:

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"IDD2QN3SGQ" = "%Documents and Settings%\%current user%\Application Data\IDD2QN3SGQ\IDD2QN3SGQ.exe"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"IDD2QN3SGQ" = "%Documents and Settings%\%current user%\Application Data\IDD2QN3SGQ\IDD2QN3SGQ.exe"

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "AB 47 8D 63 41 D4 CD 95 02 3E 92 3F E2 05 DF F8"

The process cvtres.exe:844 makes changes in the system registry.

The Worm creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "EE 58 B5 00 44 38 9C 61 AD 5E F1 82 14 BD 3F 8E"

Run a full scan of your computer.

Manual removal*

Terminate malicious process(es) (How to End a Process With the Task Manager):
%original file name%.exe:1332
csc.exe:348
cvtres.exe:844
Delete the original Worm file.
Delete or disinfect the following files created/modified by the Worm:
