Windows: require UAC elevation to enter password instead of a simple “Yes” helps preventing USB HID attacks

Posted by jpluimers on 2022/06/17

Of course you should be careful inserting random USB devices. Apart from USB HID attacks, they could perform other attacks like DMA ones.

To help preventing automated UAC elevation, you can make it harder to activate UAC by requiring a password. I think the below registry trick and policy is supported as of Windows 7, but it could be more recent (i.e. Windows 8.1).

The video below shows the trick, but does not document it in text. So here we go [WayBack] Windows doesn’t ask for your password when changing settings – Windows 10 Forums

reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "ConsentPromptBehaviorAdmin" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "ConsentPromptBehaviorUser" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableInstallerDetection" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableLUA" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableSecureUIAPaths" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "EnableUIADesktopToggle" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "FilterAdministratorToken" /t REG_DWORD /d "1" /f
reg add "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System" /v "PromptOnSecureDesktop" /t REG_DWORD /d "1" /f

(A more elaborate batch file with lots more hardening is at [WayBack] Win 10 edits · GitHub)

The registry trick is especially useful for Home editions of Windows which do not allow you to run the Security Policy control panel applet secpol.msc.

The first two values explained at [WayBack] How to configure Windows UAC prompt behavior for admins and users – gHacks Tech News:

ConsentPromptBehaviorAdmin

This key defines the User Account Control behavior for system administrators. The default value is set to prompt but do not require credentials to be entered. Here are all possible values:

  • 0: A value of 0 allows administrators to perform operations that require elevation without consent (meaning prompts) or credentials (meaning authentication).
  • 1: A value of 1 requires the admin to enter username and password when operations require elevated privileges on a secure desktop.
  • 2: The value of 2 displays the UAC prompt that needs to be permitted or denied on a secure desktop. No authentication is required.
  • 3:  A value of 3 prompts for credentials.
  • 4: A value of 4 prompts for consent by displaying the UAC prompt.
  • 5: The default value of 5 prompts for consent for non-Windows binaries.

ConsentPromptBehaviorUser

  • 0: A value of 0 will automatically deny any operation that requires elevated privileges if executed by standard users.
  • 1: The value of 1 will display a prompt to enter the username and password of an administrator to run the operation with elevated privileges on the secure desktop.
  • 3: The default value of 3 prompts for credentials on a secure desktop.

The changes should take effect immediately. You can for instance set the admin behavior to 0 so that no prompts are displayed, and user behavior to 0 as well to prevent them from running operations that require elevated privileges.

How can you export the Visual Studio Code extension list? (via: Stack Overflow)

Posted by jpluimers on 2022/06/16

Adapted from [Archive.is] How can you export the Visual Studio Code extension list? – Stack Overflow, presuming that code is on the PATH:

  1. From the command-line interface on MacOS, Linux, BSD or on Windows with git installed:
    code --list-extensions | xargs -L 1 echo code --install-extension
  2. From the command-line interface on MacOS, Linux, BSD or on Windows without git installed:
    code --list-extensions | % { "code --install-extension $_" }

    or, as I think, more clearly (see also [WayBack] syntax – What does “%” (percent) do in PowerShell? – Stack Overflow):

    code --list-extensions | foreach { "code --install-extension $_" }

    or even more explanatory:

    code --list-extensions | ForEach-Object { "code --install-extension $_" }
  3. From the command-line interface on Windows as a plain cmd.exe command:
    @for /f %l in ('code --list-extensions') do @echo code --install-extension %l
  4. On Windows as a plain cmd.exe batch file (in a .bat/.cmd script):
    @for /f %%l in ('code --list-extensions') do @echo code --install-extension %%l
  5. The above two on Windows can also be done using PowerShell:
    PowerShell -Command "code --list-extensions | % { """""code --install-extension $_""""" }"

    Note that here too, the % can be expanded into foreach or ForEach-Object for clarity.

All of the above prepend “code --install-extension ” (note the trailing space) before each installed Visual Studio Code extension.

They all give you a list like this which you can execute on any machine having Visual Studio Code installed and its code on the PATH, and a working internet connection:

code --install-extension DavidAnson.vscode-markdownlint
code --install-extension ms-vscode.powershell
code --install-extension yzhang.markdown-all-in-onex

(This is about the minimum install for me to edit markdown documents and do useful things with PowerShell).

Of course you can pipe these to a text-file script to execute them later on.

The double-quote escaping is based on [Wayback/Archive.is] How to escape PowerShell double quotes from a .bat file – Stack Overflow:

you need to escape the " on the command line, inside a double quoted string. From my testing, the only thing that seems to work is quadruple double quotes """" inside the quoted parameter:

powershell.exe -command "echo '""""X""""'"

Chocolatey on Windows 7: “You must provide a value expression on the right-hand side of the ‘-‘ operator.”

One of the places explaining a more and more frequent error on Windows 7 installations is [Wayback/Archive.is] “You must provide a value expression on the right-hand side of the ‘-‘ operator.” · Issue #29 · shiftkey/chocolatey-beyondcompare:

Windows: shutdown or reboot while preserving most of the running apps has been possible since…

Posted by jpluimers on 2022/05/26

Vista!

Shutting down or rebooting Windows allowing existing applications to reopen

Windows Vista introduced the /g switch in shutdown.exe and was unchanged in Windows 7:

    /g         Shutdown and restart the computer. After the system is
               rebooted, restart any registered applications.

I never noticed it until Windows 10 which began actively use it when applying system updates: then suddenly many of the previously running applications would reopen during startup.

Wow, the Windows 3.x winfile.exe File Manager still lives on!

Posted by jpluimers on 2022/04/01

By sheer luck, Jen Gentleman pointed out that winfile.exe still lives on:

The source is at [Wayback/Archive.is] microsoft/winfile: Original Windows File Manager (winfile) with enhancements, and it looks exactly like the Windows 3.x through Windows NT 4.0 days.
