Powerup

PowerUp aims to be a clearinghouse of common Windows privilege escalation vectors that rely on misconfigurations.

Running Invoke-AllChecks will output any identifiable vulnerabilities along with specifications for any abuse functions. The -HTMLReport flag will also generate a COMPUTER.username.html version of the report.
