Latest Message<\/th>\nTitle: Suppression rules may be edited to unintentionally suppress more alerts in the Microsoft Defender 365 portal<\/p>\n

User impact: Suppression rules may be edited to unintentionally suppress more alerts in the Microsoft Defender 365 portal.<\/p>\n

Current status: We’ve confirmed that the additional validation logic has successfully prevented further occurrences of this impact. We’re in the process of identifying the remaining rules and expect to complete correcting these rules by the next scheduled update.<\/p>\n

Scope of impact: Impact is specific to users who are served through the affected infrastructure.<\/p>\n

Root cause: A code regression is causing edited suppression rules to unintentionally suppress more alerts in the Microsoft Defender 365 portal.<\/p>\n
