Feeling too familiar with using Sysmon? You can use it for #redteam purposes by having it overwrite the #antimalware executable. Just like I did with #windowsdefender

Say hello to ChromElevator (formerly Chrome App-Bound Decryption). Just dropped v0.15.0:

🚀 One command to rule them all - can hit every installed Chromium browsers at once.
🤫 More stealthy discovery as it finds browser paths by querying the registry with direct syscalls. No more hardcoded paths!
🛡️ Smarter EDR evasion, resilient decryption and more.

For the life of me I can never remember the registry tweaks to avoid TPM checks when installing Win11 in a VM. I finally took note of the `reg add` commands to just copy and paste into the Shift+F10 terminal.

reg add "HKLM\SYSTEM\Setup\LabConfig" /f
reg add "HKLM\SYSTEM\Setup\LabConfig" /v BypassTPMCheck /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\Setup\LabConfig" /v BypassSecureBootCheck /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\Setup\LabConfig" /v BypassRAMCheck /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\Setup\LabConfig" /v BypassCPUCheck /t REG_DWORD /d 1 /f
reg add "HKLM\SYSTEM\Setup\LabConfig" /v BypassStorageCheck /t REG_DWORD /d 1 /f
