Screenconnect attacks where some automatic remediations fail
I am starting to see a new pattern of Screenconnect style attacks (via phishing) that always leaves some automatic remediations unable to complete. The components of this are twofold, and am hoping that maybe with this feedback, it can become more automated in the future. These issues always seem to manifest as a permissions-related issue with deleting the infected folders. This occurs for one of two reasons: The permissions are truly locked down on the folder and have to be forcefully re-added to a local administrator so deletion can occur. In both cases I have seen, I have had to use the following commands to allow deletion: takeown /f " insert path to folder/file here " /r /d y icacls " insert path to folder/file here " /grant Administrators:F /t /c /q Sometimes though, this is not even enough, and the reason for it is worrisome. These screenconnect attacks have gone so far as to modify a key registry value that injects a malicious dll file upon boot, even in safe mode. The path to the key is: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Lsa\Authentication Packages Normally, this key only reads "msv1_0" however in an infected machine, it will have the path to a malicious dll appended to the end. Subsequently the dlls cannot be deleted until this appended path is removed, and system is rebooted. I suspect that if the automated response is aware of these needed changes, it might be able to be removed without our direct intervention.

Managed Exclusions needs bulk management, persistent filters, group-based targeting, and API support
A partner managing Huntress Managed Microsoft Defender exclusions ran into significant usability issues while trying to add 2 endpoints to roughly 12 existing exclusions in a single org. In its current form, this workflow is highly manual and does not scale well for real-world administration. -- Current pain points: Managed Exclusions are currently scoped only at the account, organization, or endpoint level; there is no way to target exclusions by machine type, tag, or group. The partner wants to apply exclusions to a subset of systems within an org, such as a logical grouping like FSLogix hosts, without having to manage each endpoint individually. Editing exclusions appears to be effectively one-at-a-time for this workflow, making repetitive changes across many exclusions slow and frustrating. After each edit, the UI resets filters, forcing the admin to re-find their place and repeat the same navigation over and over. The partner explicitly described this as one of the worst UX experiences they have had in a long time, which suggests this is more than a minor inconvenience and is likely to create friction for larger or more mature environments. -- Public API support for Managed Exclusions Expose Managed Exclusions management through the Huntress API so partners can automate: Listing exclusions Creating exclusions Updating exclusion scope Bulk assigning endpoints Removing endpoints from exclusions This would allow partners to automate repetitive changes that are currently manual in the UI.
