About

SCAM Lock Tool is a replacement for SAM Lock Tool (better known as syskey), which is used to encrypt the account credentials stored inside the SAM file. Tech support scammers use syskey to lock their victims out of their computer, but with SCAM Lock Tool they won't be able to do it.

How to replace syskey

• Open an elevated Command Prompt and run the following commands:

takeown /F syskey.exe
icacls syskey.exe /T /C /GRANT Everyone:F

• Rename the original syskey.exe or move it somewhere else to make a backup.
• Copy my version of syskey.exe inside C:\Windows\System32, including INIFileParser.dll.
• If you want to customize SCAM Lock Tool behavior copy syskey.ini as well or create it. See the Settings section for more information.

Settings

SCAM Lock Tool behavior can be configured by using a syskey.ini file. For example, you can decide to display an error or open the Tech Support Scam Wikipedia page when attempting to change the Startup Key.

The settings file is optional.

The syskey.ini file must be placed alongside syskey.exe.

Elements of syskey.ini

[syskey]

The syskey section can include the following properties:

Property	Type	Default	Description
behavior	Integer	0	If set to 0, it will show an error when attempting to change the Startup Key. If set to 1, it will show an error message and will open the Tech Support Scam Wikipedia page when attempting to change the Startup Key.. If set to 2, it will show a message saying that the Startup Key was changed successfully.
message	String	An error occurred while attempting to scam this user.	If behavior is set to 1 shows a custom error message. Include $PASSWORD to display the typed password in the error message. Don't surround the custom message with quotation marks otherwise they will appear in the error message.
