AN0607: Analytic 0607
Detection focuses on unauthorized modification of Mach-O binaries to include LC_LOAD_DYLIB headers pointing to malicious dylibs. Behavior is identified via a chain of file metadata changes, removal of code signatures, and subsequent anomalous dylib loads at runtime. Correlation of file changes with lack of authorized updates and process memory mapping of unrecognized or unsigned libraries is crucial.
Automated summary not available
Glexia publishes ATT&CK takes only after source-hash and schema validation. Until then, use the official MITRE definition below and the defensive relationship context on this page.

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates.
Imported snapshots across ATT&CK releases(3)

Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
