  "bluf": "MITRE ATT&CK T1546.006 (LC_LOAD_DYLIB Addition) is an Enterprise Privilege Escalation and Persistence sub-technique of T1546 (Event Triggered Execution). Adversaries may establish persistence by executing malicious content triggered by the execution of tainted binaries. Mach-O binaries have a series of headers that are used to perform certain operations when a binary is loaded. The LC_LOAD_DYLIB header in a Mach-O binary tells macOS and OS X which dynamic libraries (dylibs) to load during execution time. These can be added ad-hoc to the compiled binary as long as adjustments are made to the rest of the fields and dependencies. Affected platforms: macOS. MITRE-documented mitigations include M1047 Audit, M1038 Execution Prevention, M1045 Code Signing. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-02, AC-03, AC-06, CM-02, CM-03, CM-06, CM-07, CM-08.",
