%original file name%.exe:2528
vbc.exe:316
Explorer.EXE:2024

Mutexes

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

File activity

The process %original file name%.exe:1900 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

C:\Users\"%CurrentUserName%"\AppData\Local\Temp\vbc.exe (7596 bytes)

The process vbc.exe:316 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):

C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe (1377 bytes)
C:\Users\"%CurrentUserName%"\AppData\Roaming\local (33 bytes)

Registry activity

The process vbc.exe:316 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:

[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"KUJFEEWHA4" = "September 17, 2017"

[HKLM\SOFTWARE\Microsoft\Active Setup\Installed Components\{E8A5C2C7-DAEA-BEAC-3CEE-F9B2FDB5BBD8}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe"

[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"KUJFEEWHA4" = "Papi"

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"msnmsgrs" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe"

[HKCU\Software\Microsoft\Active Setup\Installed Components\{E8A5C2C7-DAEA-BEAC-3CEE-F9B2FDB5BBD8}]
"StubPath" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.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]
"msnmsgrs" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe"

[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"msnmsgrs" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe"

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.

   C:\Users\"%CurrentUserName%"\AppData\Roaming\local (33 bytes)

4. Delete the following value(s) in the autorun key (How to Work with System Registry):
   

   [HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
   "msnmsgrs" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe"
   
   [HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
   "msnmsgrs" = "C:\Users\"%CurrentUserName%"\AppData\Roaming\msnmsgrs.exe"

5. Clean the Temporary Internet Files folder, which may contain infected files (How to clean Temporary Internet Files folder).
   
6. Find and delete all copies of the worm's file together with "autorun.inf" scripts on removable drives.
