Objective-See’s Mac malware year-in-review covered several macOS threats from 2019, including Lazarus-linked activity against cryptocurrency businesses. The source notes Lazarus group backdoors and CookieMiner-style activity that used launch agents for persistence and attempted to exfiltrate data to attacker-controlled command infrastructure. The report is a broad macOS malware survey rather than a single campaign write-up, but it preserves useful context on DPRK-linked macOS targeting of cryptocurrency users and businesses. Defenders can use it to map persistence, backdoor, and miner behaviors observed across macOS malware families from that period.
