Which Perfect Sandstorm subgroup keeps displayed its ability to rapidly embrace recently stated N-day vulnerabilities on its playbooks. To advance get rid of business coverage, Microsoft Defender getting Endpoint consumers are able to use the fresh chances and you can vulnerability management capability to find, focus on, and you can remediate vulnerabilities and you will misconfigurations.

Decreasing the attack epidermis

Microsoft 365 Defender users may also stimulate assault facial skin protection statutes so you can solidify their environments facing processes used by which Mint Sandstorm subgroup. These types of laws and regulations, that’s configured from the the Microsoft Defender Anti-virus customers and you may not just men and women utilising the EDR services, bring extreme safety against the tradecraft discussed inside report.
