ASR - Behavior Changes - Blocking under User Context Now?
Since July 7-27-2022 I have been seeing around 40 of 1800 machines in my work environment that are showing blocks under %userprofile% or usercontext for .dll blocks. This is new behavior and is rece...
- Aug 15, 2022I've so far only managed to check on one endpoint that was having the issue, However it's Security Intelligence Version updated to 1.373.383.0 this morning and it is no longer showing any symptoms of the problem. So early signs are encouraging that this may be fixed.

Thanks for the report! We were alerted to this thread out on Twitter and wanted to share that we’ve connected with our friends on the Defender for Endpoint team and confirmed that a signature update will be rolled out over the next few hours to resolve this issue.

ok to finish our experience: after 2 more fixes from microsoft we seem to be fine now
some users that had problems dont have them anymore
in reports -> ASR rules i also dont see any more blocks of our 3rd party software in "block exe content from email and webmail" so bit early to be sure but for now it looks like all is fixed for us

- shend141Aug 16, 2022Copper ContributorSince Microsoft rolled out 1.373.383.0 released 8/15/2022 3:28:43 AM (I'm currently on 6 versions higher than 383: 410>421>435>449>452>460), ASR detections have certainly fallen which is a good sign, but we’re still seeing some detections for safe/known DLL such as iManage, Acrobat etc.
We can carry out manual Defender updates and reboots. In the meantime, can you advise if we need to do anything else to remove these false-positive detections please?
