"This is caused by a new feature enabled in 8.3, where we check the signature level of every DLL loaded into cytray.exe. The application's DLL must be unsigned or with a lower trusted level, which will result in the DLL being blocked by us and this pop-up to show. hence we have provided the SUEX to disable the feature.
At the moment the engineering team does not consider this issue as an actual bug inside the product, but rather a by-design behavior.
I would like to inform you that it might be fixed in the upcoming version of the XDR Agent, but we do not have an ETA for this."
