Analysis

qmbsec.sys is identified as pe for 32 systems. The subsystem is Native. PE header values are useful for triage, especially when they do not match the expected publisher, product, or release timeline.

PE section names and hashes can reveal packing, injected resources, or unusual build artifacts. Sections with uncommon names, very large raw data, or hashes that differ from a trusted copy deserve additional review.
