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 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:1620
reg.exe:1436
reg.exe:1652
reg.exe:1584
reg.exe:480
The Worm injects its code into the following process(es):
vbc.exe:460
File activity
The process %original file name%.exe:1620 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\windows.exe (1755 bytes)
The process vbc.exe:460 makes changes in the file system.
The Worm creates and/or writes to the following file(s):
%Documents and Settings%\%current user%\Application Data\keylog (34 bytes)
Registry activity
The process %original file name%.exe:1620 makes changes in the system registry.
The Worm creates and/or sets the following values in system registry:
[HKLM\SOFTWARE\Microsoft\Cryptography\RNG]
"Seed" = "FE 45 E7 B5 9B 33 BF 94 C1 59 B3 35 D0 F0 8D 5E"
[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 Worm adds the following link to its file to the system registry autorun key:
[HKCU\Software\Microsoft\Windows\CurrentVersion\Run]
"Windows Firewall" = "C:\DOCUME~1\"%CurrentUserName%"\LOCALS~1\Temp\windows.exe"
The process vbc.exe:460 makes changes in the system registry.
