Everything you need to know about the Microsoft Exchange Server hack

HOW CAN I CHECK MY SERVERS AND THEIR VULNERABILITY STATUS? WHAT DO I DO NOW?

Microsoft has urged IT administrators and customers to apply the security fixes immediately. However, just because fixes are applied now, this does not mean that servers have not already been backdoored or otherwise compromised.

Interim mitigation option guides are also available if patching immediately is not possible.

The Redmond giant has also published a script on GitHub available to IT administrators to run that includes indicators of compromise (IOCs) linked to the four vulnerabilities. IoCs are listed separately here.

CISA issued an emergency directive on March 3 that demanded federal agencies immediately analyze any servers running Microsoft Exchange and to apply the firm’s supplied fixes.
