| # Simple script to check drivers in C:\windows\system32\drivers against the loldrivers list | |
| # Author: Oddvar Moe - @oddvar.moe | |
| # Fork changes: | |
| # Drivers can also reside in driverstore\filerepository subdir | |
| # To check them also, $drivers should be with -recurse and get-filehash from real file $drivers file rather than assumed system32 path with filename | |
| $drivers = get-childitem -Path c:\windows\system32\drivers -recurse | |
| $web_client = new-object system.net.webclient | |
| $loldrivers = $web_client.DownloadString(" https://www.loldrivers.io/api/drivers.json") | ConvertFrom-Json | |
| Write-output("Checking {0} drivers in C:\windows\system32\drivers\* against loldrivers.io json file" -f $drivers.Count) | |
| foreach ($lol in $loldrivers.KnownVulnerableSamples) | |
| { | |
| # Check for matching driver name | |
| if($drivers.Name -contains $lol.Filename) | |
| { | |
| #CHECK HASH | |
| $Hash = ( $drivers | where Name -eq $lol.Filename | Get-FileHash ) | |
| if($lol.Sha256 -eq $Hash.Hash) | |
| { | |
| write-output("The drivername {0} is vulnerable with a matching SHA256 hash of {1}" -f $lol.Filename, $lol.SHA256) | |
