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 have been edited to unintentionally suppress more alerts in the Microsoft Defender 365 portal.<\/p>\n

Final status: We\u2019ve confirmed with our internal telemetry system that correcting the remaining rules has been completed and the issue is resolved. <\/p>\n

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

Start time: Thursday, August 24, 2023, at 3:39 PM UTC<\/p>\n

End time: Thursday, September 7, 2023, at 3:00 PM UTC<\/p>\n

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

Next steps:
– We’re reviewing the code regression and how it unintentionally suppressed more alerts than intended to prevent this from reoccurring in the future.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
