TL;DR: macOS malware in 2018 leaned on RATs, trojans, cryptomining and phishing-led wallet theft, with SentinelOne describing Empyre and trusted channels as recurring delivery paths. macOS defenses need provenance checks and runtime monitoring, because trust decisions can let malicious software look routine.
Editorial analysis by NHI Mgmt Group, based on content published by SentinelOne: “A Review of Malware Affecting macOS in 2018”.
Key questions
Q: Why do macOS RATs and trojans increase privilege and lateral access risk?
A: They turn an endpoint infection into a reusable access path.
Q: How do security teams detect persistence on macOS endpoints?
A: Focus on new LaunchAgents, unexpected binaries in Application Support, and processes that reappear after termination.
Q: What fails first when a signed macOS app turns out to be malicious?
A: The first failure is trust in the distribution path, not necessarily code execution control.
Practitioner guidance
- Harden application provenance checks Require validation of software origin, signing context and expected runtime behaviour before allowing installation or execution in managed macOS estates.
- Monitor LaunchAgents and LoginItems Alert on new persistence entries, especially those created by utilities, updaters or archive-based installers that should not establish background execution.
- Restrict privilege escalation paths Review which user actions can elevate permissions on macOS and remove unnecessary admin rights from employees who do not need them.
Bottom line: The main lesson from this macOS malware year is that trusted software paths can be more dangerous than obvious exploits when attackers can hide behind normal execution cues.

Platform trust was the real attack surface in 2018 macOS malware. The article shows that signed software, trusted apps, user-approved utilities and expected installer workflows were all turned into delivery mechanisms. That means the weak point was not only exploitation. It was the assumption that trusted distribution paths are inherently safe. Practitioners should treat trust boundaries as security controls that need continuous verification.
A question worth separating out:
Q: What should organisations do when trusted channels are used to deliver macOS malware?
A: Treat the channel as compromised for governance purposes and raise controls around install approval, download handling and privilege elevation. When attackers can use app stores, signed packages or user trust to reach execution, the control response has to shift from simple malware blocking to stronger provenance checks and tighter runtime monitoring.
