Dynamic Analysis

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 Trojan's file once a user opens a drive's folder in Windows Explorer.

Process activity

The Trojan creates the following process(es):

%original file name%.exe:2696
%original file name%.exe:1048

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

svchost.exe:2548
iexplore.exe:2968

Mutexes

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

File activity

The process %original file name%.exe:2696 makes changes in the file system.

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

C:\Users\"%CurrentUserName%"\AppData\RoamingMicrosoft\System\Services\18.exe (601 bytes)

The process %original file name%.exe:1048 makes changes in the file system.

The Trojan deletes the following file(s):

C:\Users\"%CurrentUserName%"\AppData\Local\Temp\x.html (0 bytes)

Registry activity

The process %original file name%.exe:2696 makes changes in the system registry.

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

[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\DDECache\IExplore\WWW_OpenURL]
"processname" = "iexplore.exe"
"WindowClassName" = "DDEMLMom"

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

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "C:\Users\"%CurrentUserName%"\AppData\RoamingMicrosoft\System\Services\18.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "C:\Users\"%CurrentUserName%"\AppData\RoamingMicrosoft\System\Services\18.exe"

The process %original file name%.exe:1048 makes changes in the system registry.

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

[HKCU\Software\XtremeRAT]
"Mutex" = "--((Mutex))--"

Dropped PE files

There are no dropped PE files.

HOSTS file anomalies

No changes have been detected.

Rootkit activity

No anomalies have been detected.

Propagation

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 Trojan's file once a user opens a drive's folder in Windows Explorer.

Removals

Remove it with Ad-Aware

Click (here) to download and install Ad-Aware Free Antivirus.
Update the definition files.
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:2696
%original file name%.exe:1048
Delete the original Trojan file.
Delete or disinfect the following files created/modified by the Trojan:
C:\Users\"%CurrentUserName%"\AppData\RoamingMicrosoft\System\Services\18.exe (601 bytes)
Delete the following value(s) in the autorun key (How to Work with System Registry):
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "C:\Users\"%CurrentUserName%"\AppData\RoamingMicrosoft\System\Services\18.exe"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"18.exe" = "C:\Users\"%CurrentUserName%"\AppData\RoamingMicrosoft\System\Services\18.exe"
Clean the Temporary Internet Files folder, which may contain infected files (How to clean Temporary Internet Files folder).
Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
Reboot the computer.

*Manual removal may cause unexpected system behaviour and should be performed at your own risk.
