Trojans Claim Half of Mac Malware Detections, Jamf Warns
Jamf reports Trojan malware now represents 50% of all Mac detections, surging past adware. This erodes Macs' security edge, forcing enterprises to rethink protections amid a maturing threat ecosystem.

This shift marks a stark departure from the adware-heavy past. In 2023, adware comprised 65% of threats; now it's down to 33%. Trojans exploit user trust—often masquerading as legitimate apps or hiding in cracked software downloads—targeting macOS's growing user base of 1.4 billion active devices.
For Apple users and IT teams, the implications are dire. Macs long enjoyed a reputation for inherent security, but relaxed vigilance amid rising popularity has opened the floodgates. Enterprises relying on Jamf Protect saw 2.5 times more Trojan detections in Q1 2024 alone, underscoring the need for endpoint detection beyond basic Gatekeeper checks.
Jamf attributes the boom to macOS Sonoma's expanded attack surface and phishing campaigns tailored for Apple fans. Competitors like Microsoft Defender for Endpoint report similar upticks, signaling a maturing Mac threat landscape that rivals Windows.
What happens next? Expect Apple to tighten Safari and XProtect signatures in upcoming updates, while security vendors race to counter evolving stealers. Users ignoring this trend risk data breaches; admins must deploy AI-driven EDR now to stay ahead.
EXPERT TAKE
Mac admins: Layer EDR with privilege management and zero-trust access immediately—Jamf data shows Trojans evading AV alone in 70% of cases.
