So it Mint Sandstorm subgroup have exhibited its ability to easily embrace newly stated Letter-day vulnerabilities toward its playbooks. To advance eradicate business exposure, Microsoft Defender getting Endpoint customers can use the newest possibilities and you can vulnerability administration capability to select, prioritize, and you may remediate weaknesses and you may misconfigurations.

Decreasing the assault epidermis

Microsoft 365 Defender customers also can activate attack surface avoidance laws so you’re able to harden its environment against processes utilized by which Perfect Sandstorm subgroup. These laws, which will be designed because of the all Microsoft Defender Antivirus consumers and you can not merely people making use of the EDR solution, give tall safeguards from the tradecraft discussed in this report.
