Latest Message<\/th>\nTitle: Admins may receive false positive indications in Microsoft Defender vulnerability management for a specific app<\/p>\n

User impact: Admins may receive false positive indications in Microsoft Defender vulnerability management for a specific app.<\/p>\n

Current status: We\u2019ve developed and completed the deployment of the fix to a subset of the affected environment, and some admins may already see signs of improvement. We\u2019re continuing to monitor the environment to ensure the fix is operating as expected prior to its deployment to the remainder of affected admins.<\/p>\n

Scope of impact: Some admins expecting to receive indications of vulnerabilities in Microsoft Defender for Endpoint for devices with a specific app may be impacted.<\/p>\n

Start time: Monday, July 14, 2025, at 4:00 AM UTC<\/p>\n

Root cause: A configuration error in our detection model has resulted in Acrobat Reader executables being marked falsely as Acrobat Reader DC, which is resulting in admins receiving false-positive vulnerability indications.<\/p>\n

Next update by: Thursday, July 24, 2025, at 6:00 PM UTC<\/td>\n<\/tr>\n
