A global attack on the popular Microsoft Exchange email server system has become a global crisis.
This hack became public knowledge on March 2, 2021, with Microsoft releasing multiple software patches to address vulnerabilities that hackers were exploiting. Microsoft and other groups are referring to the originating hacking group as “Hafnium.”

On March 5th, Microsoft released tools to help investigate if your server has been affected by this breach.
Turn Key Solutions is URGENTLY recommending everyone to do 3 things if you run a Microsoft Exchange Server:
- Pull up your Cyber Security Incident Response plan
- If your organization runs an in-house Microsoft Exchange Server, apply the patches right now. Here’s the article for them – Multiple Security Updates Released for Exchange Server – updated March 5, 2021 – Microsoft Security Response CenterOf note, our technical team has found a few issues where the patches can need a bit of extra attention to apply correctly and not hang the exchange server up for hours.
- Run the investigation tools and scripts to search for indicators that your system was compromised. See Microsoft’s guidance here – HAFNIUM targeting Exchange Servers with 0-day exploits – Microsoft Security
