Most Mac breaches start with social engineering (disabling Gatekeeper via terminal commands) or weak user privileges (running daily work as admin). 2. Apple’s Native Security Stack: What It Does (and Doesn’t Do) Apple provides a solid foundation—but with gaps.

We provide a layered framework combining Apple’s native security stack with third‑party controls, configuration hardening (CIS benchmarks), and continuous monitoring. For years, attackers ignored Macs due to low market share. That era is over.
Any EDR must have full disk access (FDA) and kernel extension approval (or System Extensions on Apple Silicon). Without FDA, you cannot scan ~/Library/Keychains or ~/Library/Mail . 5. Detection Queries Every Mac Admin Should Run Use these to hunt for compromise (via your EDR or osquery ). 5.1 Suspicious LaunchAgents (Persistence) SELECT * FROM launchd WHERE path LIKE '/Users/%/Library/LaunchAgents/%' AND (name LIKE '%update%' OR name LIKE '%java%' OR name LIKE '%google%'); -- Look for masquerading names 5.2 Users Running with UID 0 (Privilege Escalation) ps aux | awk '$1=="root" print $11' | sort -u # Check for unexpected processes like Python, Ruby, Node running as root 5.3 Bypass of Gatekeeper find /Applications -name "*.app" -exec spctl --assess --verbose {} \; # Any output "rejected" is fine; "accepted" but from untrusted source is suspicious 5.4 Unusual AppleScript Usage (UI control) grep -r "osascript" /Users/*/Library/Logs/ # Combined with login items = possible infostealer 5.5 Keychain Access Attempts Monitor security command line invocations:
