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:1736
The Trojan injects its code into the following process(es):
cvtres.exe:1500
Mutexes
The following mutexes were created/opened:
No objects were found.
File activity
The process %original file name%.exe:1736 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):
%Documents and Settings%\%current user%\Local Settings\Temp\cvtres.exe (35 bytes)
The process cvtres.exe:1500 makes changes in the file system.
The Trojan creates and/or writes to the following file(s):
%Documents and Settings%\%current user%\Application Data\MsComlclt (33 bytes)
%Documents and Settings%\%current user%\Application Data\local.exe (35 bytes)
Registry activity
The process %original file name%.exe:1736 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:
[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "67 D1 09 67 87 8F D9 1D 40 AF 5A 3C F7 CA 98 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"
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]
"Windows Live" = "c:\%original file name%.exe"
The process cvtres.exe:1500 makes changes in the system registry.
The Trojan creates and/or sets the following values in system registry:
[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "7D 5F BD E9 4F 50 C8 0E 71 C5 A6 3A C0 83 09 46"
[HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]
"AppData" = "%Documents and Settings%\%current user%\Application Data"
[HKCU\Software\VB and VBA Program Settings\SrvID\ID]
"E7692TQ3UN" = "Local"
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\Explorer\Run]
"Windows" = "%Documents and Settings%\%current user%\Application Data\local.exe"
[HKCU\Software\VB and VBA Program Settings\INSTALL\DATE]
"E7692TQ3UN" = "September 23, 2014"
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]
"Windows" = "%Documents and Settings%\%current user%\Application Data\local.exe"
[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"Windows" = "%Documents and Settings%\%current user%\Application Data\local.exe"
