Pwncheck 1.0.30 and a database update

We’re delighted to announce the latest release of pwncheck 1.0.30 – the fastest and safest way to find users with pwned passwords on your Active Directory network, offline and without sending your hashes to the cloud.

The purpose of this release is to bring pwncheck inline with the latest version of Troy Hunt’s Have I Been Pwned database, using the new API described in this blog post. The number of unique breached passwords we now check against is over 851 million.

We recommend that you run pwncheck to ensure that none of your Active Directory users are currently using a compromised password, likely to be present in the latest credential stuffing and password spraying lists.

The latest pwncheck documentation has been updated accordingly and can be downloaded here

To update (assuming you are running v8.0.5), you can use the following powershell script:

#Stop on error
$ErrorActionPreference = “Stop”
#speedup Invoke-WebRequest
$ProgressPreference = ‘SilentlyContinue’

#download the database
Invoke-WebRequest -Uri -OutFile \HIBPv8-extra.dat
if ((Get-FileHash -Algorithm SHA256 \HIBPv8-extra.dat).Hash -ne “12C9BE9E844BD75F4F1FA1F1F754A68A1AAE7ECF113024BB3A06464B04DAD2B9”) {
Write-Error “Error downloading HIBPv9-extra.dat”
Invoke-WebRequest -Uri -OutFile \HIBPv8.dat
if ((Get-FileHash -Algorithm SHA256 \HIBPv8.dat).Hash -ne “EE1B91DD723474D06264CFCEAE6E2363F5B12C210D23388AF86F1430041753DB”) {
Write-Error “Error downloading HIBPv9.dat”

#upload it to the DCs
Get-ADDomainController -filter *|%{
Start-Job -Name “SafePass-$_” -ArgumentList ($_) -ScriptBlock {
