Latest Message<\/th>\nTitle: Users may have experienced corrupted file hashes instead of empty values for ProcessCreated and ImageLoaded action types<\/p>\n

User impact: Users may have experience corrupted file hashes instead of empty values for ProcessCreated and ImageLoaded action types.<\/p>\n

More info: Affected users may have experienced random-looking file hashes instead of empty values for 1.6 percent of Microsoft Defender for Endpoint ProcessCreated and ImageLoaded events. Other events, including events with proper hashes, weren’t affected.<\/p>\n

Impact may have been specific to Microsoft Defender for Endpoint users that were using the following KB versions:<\/p>\n

Windows 10 22h2 – KB5058481 (released on May 28th 2025)
Windows 10 21H2 – KB5060533 (released on June 10th 2025)
Windows 11 24H2 – KB5058499 (released on May 28th 2025)
Windows 11 23H2\/22H2 – KB5058502 (released on May 27th 2025
Windows Server 2019 \/ Windows 10 (build 1809) – KB5060531 (released on June 10th 2025)
Windows Server 2022 – KB5060526 (released on June 10th 2025)
Windows Server 2025- KB5060842 (released on June 10th 2025)<\/p>\n

Final status: We’ve validated and deployed the fix to the affected infrastructure. Additionally, we’ve confirmed impact is no longer occurring after a period of monitoring.<\/p>\n

Scope of impact: Some users who received hash values for ProcessCreated and ImageLoaded action types within Microsoft Defender for Endpoint may have been impacted.<\/p>\n

Start time: Wednesday, May 28, 2025, at 12:00 AM UTC<\/p>\n

End time: Thursday, July 10, 2025, at 8:45 AM UTC<\/p>\n

Root cause: A code issue contained within a Microsoft Defender for Endpoint service update was causing impact.<\/p>\n

Next steps:
– We’re reviewing our service update procedures to help prevent similar impact from happening again.<\/p>\n

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