I was asked if there is an easy way to check the complete Active Directory for systems that miss the WannaCry related Hotfixes are installed.

Yep! And it’s even easy to do.

Based upon several requests, I also published a small tool that could do the Job. You will find the tool (freeware) on GitHub.

Check System for CVE-2017-0290

This content is older than 1 year. It might be outdated.

A code-execution vulnerability was found in the Microsoft Malware Protection Engine with Engine Version before 1.1.13704.0. This vulnerability is known as CVE-2017-0290.

The good news: Microsoft already released a fix for this issue!

Here is a quick way to check if a system is vulnerable:

# Returns a Bool (yep. just True or False) for CVE-2017-0290 vulnerability
(Get-MpComputerStatus).AMEngineVersion -ge '1.1.13704.0'
# If you see False you should update your Defender Definition File As Soon Ass Possible (ASAP)

Ein PSCredential gegen Active Directory validieren

Ich wollte eine einfache Möglichkeit eine per Get-Credential in eine Variable gespeichertes PSCredential Objekt.
Es gibt Unmengen an Funktionen die das könne. Allerdings wird der BadLogonCount bei den meisten direkt um 2 erhöht. Das liegt daran, dass die meisten einen Bind machen und dann einen Befehl im Context absetzten. Das wollte ich aber nicht!
