GrimResource - Microsoft Management Console for initial access and evasion

Elastic researchers identified GrimResource, a technique that achieves remote code execution through maliciously crafted Microsoft Management Console (MSC) files. The discovery highlights adversary adoption of novel initial access methods designed to bypass contemporary defenses.

Why it matters: Organizations relying on MSC files for administration face a new execution vector; security teams should review detection coverage for suspicious MSC file activity and refine allowlisting rules on trusted management consoles.
