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.

Enhanced Control and Visibility for Chromium-Based Browser Extensions
As browser-based applications become central to modern workflows, the security risks associated with Chromium-based browser extensions are increasing significantly. We request improved monitoring, control, and policy enforcement capabilities for browser extensions to mitigate risks related to malicious plugins and shadow IT. In today’s work environment, the reliance on browser applications continues to grow. At the same time, the number of malicious or compromised extensions in the Chrome Web Store and other Chromium-based marketplaces is rising rapidly. This creates several security challenges: Malicious extensions can exfiltrate sensitive data, inject scripts, or act as persistence mechanisms. Shadow IT risks increase as users install extensions tied to unapproved SaaS platforms, leading to uncontrolled data distribution. Lack of centralized visibility makes it difficult for IT and security teams to audit and manage extension usage across endpoints. Existing endpoint security solutions, including Huntress, have limited visibility and control over browser extensions, particularly: No centralized inventory of installed extensions Limited insight into extension permissions and behaviors No enforcement of allow/block policies at scale Lack of alerting on high-risk or newly installed extensions We propose adding dedicated browser extension security capabilities, including: Extension Inventory & Visibility Centralized dashboard of all installed Chromium extensions across endpoints - Metadata including publisher, permissions, install source, and user Risk Assessment & Detection Flag extensions with high-risk permissions (e.g., access to all sites, clipboard, downloads) Detection of known malicious or suspicious extensions Alerts on newly installed or recently updated extensions Policy-Based Control Ability to create allowlists and blocklists Enforcement of approved extensions only Optional auto-removal or disablement of unauthorized extensions Shadow IT Insights Identify extensions linked to unapproved SaaS or data-sharing services Reporting on potential data exposure vectors Integration & Response Tie extension activity into existing Huntress detection and response workflows Enable automated or guided remediation actions Conclusion: As browsers increasingly function as primary work platforms, extension security must be treated as a first-class concern. Enhanced control and visibility over Chromium extensions would provide significant security value to customers operating in today’s threat landscape.
