Summary:

Trojan. A program that appears to do one thing but actually does another (a.k.a. Trojan Horse).

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:312

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

%original file name%.exe:1416

Mutexes

The following mutexes were created/opened:

ShimCacheMutex
V9DWCT5FHB

File activity

The process %original file name%.exe:1416 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

%Documents and Settings%\%current user%\Application Data\waucltt.exe (1330 bytes)
%Documents and Settings%\%current user%\Application Data\data.dat (34 bytes)

Registry activity

The process %original file name%.exe:1416 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:

[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "EF 2A 0D E1 32 F7 36 09 8E 15 00 D4 F1 AE 11 68"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"V9DWCT5FHB" = "Youtube"

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"V9DWCT5FHB" = "August 13, 2016"

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

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

[HKCU\Software\Microsoft\Active Setup\Installed Components\{ADFCBCE1-BAA7-F62E-563D-CCF7EEADBDFD}]
"StubPath" = "%Documents and Settings%\%current user%\Application Data\waucltt.exe"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{ADFCBCE1-BAA7-F62E-563D-CCF7EEADBDFD}]
"StubPath" = "%Documents and Settings%\%current user%\Application Data\waucltt.exe"

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

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

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

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.
