Cybersecurity Alert - FINRA Notifies Member Firms of Microsoft Alert (CVE-2022-30190)

FINRA’s National Cause and Financial Crimes Detection (NCFC) Cyber and Analytics Unit (CAU) has noted a recent alert issued by Microsoft on May 30, 2022.

The Microsoft alert describes a remote code execution vulnerability, named “Follina” by security analysts, related to the Microsoft Support Diagnostic Tool (MSDT) that can be used by a threat actor to run malicious code. As a result, a threat actor could install programs; view, change, or delete data; or create new accounts on the network.

The Microsoft alert, associated with CVE-2022-30190, recommends disabling the MSDT tool and provides instructions to implement this recommendation.
