NTT Security published a white paper on malicious Microsoft Management Console MSC files, a technique observed across multiple attack campaigns beginning around March 2024. The report explains how MSC functionality such as Taskpad can be abused to execute arbitrary commands and describes three known exploitation approaches, observed usage, and defensive guidance. Although the article is a publication notice rather than a single intrusion report, it is relevant CTI because malicious MSC files provide a Windows-native execution path that threat actors can use for initial access, payload staging, and defense evasion. Defenders should review MMC and MSC execution telemetry, monitor suspicious command launches from mmc.exe, and apply the detection and mitigation recommendations in the white paper.
