BlueNoroff
IIM chain for LevelBlue SpiderLabs research published on 2026-05-28. The report describes a Sapphire Sleet / BlueNoroff / UNC1069 macOS campaign targeting financial, Web3, venture-capital and cryptocurrency environments. Initial access uses social engineering around a fake video meeting and a fake Zoom SDK update component. The user executes Zoom SDK Update.scpt, which opens in macOS Script Editor and drives an osascript/curl/shell chain using task-specific User-Agents mac-cur1 through mac-cur5. Follow-on components include com.apple.cli profiling tooling, a native-looking systemupdate.app Mac Password Popup credential harvester, TCC.db abuse through Finder, a LaunchDaemon plist for persistence, an icloudz backdoor component, and the in-memory com.google.chromes.updaters beacon agent. Exfiltration is staged into /tmp zip archives and uploaded over remote upload/exfil ports. LevelBlue publishes C2 domains, C2 IPs, operational ports, hashes, and strategic forensic paths; exact lure accounts, meeting URLs, and per-domain DNS mappings are not published and are therefore not invented in this chain.
