Each year, Jamf—the popular Apple device management platform—releases its Security 360: Annual Trends Report, which gives a broad outlook of the macOS threat landscape currently facing businesses and users. The analysis uses anonymized real-world data collected from 1.4 million Macs across 90 countries with Jamf software installed.

Today, Jamf is out with its 2025 edition, which spans the previous 12 months. The report offers many shocking insights, most notably a 28% spike in infostealer malware, making it the leading Mac malware family type.

Key findings from the report

32% of organizations operate at least one device with critical (and patchable) vulnerabilities Jamf identified approximately 10 million phishing attacks in the past year, with 150,000 to 200,000 of these attacks being classified as zero day attacks 25% of organizations were impacted by a social engineering attack Infostealers continue to surge in popularity, now the leading Mac malware family, accounting for 28.36% of all Mac malware detected 1 in 10 users clicked on a malicious phishing link Over 90% of cyber attacks originate from phishing

Today’s report from Jamf highlights which types of malware are wreaking the most havoc.

For the first time, infostealers have overtaken adware as the dominant form of malware caught by Jamf users. Infostealers saw a 28.08% increase, surpassing adware with now 28.36% of total malware samples analyzed.
