Foxveil/AMOS macOS reflective loader, universal Mach-O (x86_64+arm64, 1,495,488 B). Served from a new delivery host chantcompass9.com at /f/yhzuuxkyytoc-pr6sqaaqa/lvitjpau, fetched via Tor 2026-10-13 22:35 UTC. Reached through a zsh dropper (/curl/ltlmtyrcu/3idd7eprmh6is0juh3.json) whose decoded stage-2 posts telemetry to raster-87.com/api/metrics/run and then downloads and runs this payload. Statically opened: same AMOS AppleScript stealer as Foxveil quill build b539c4cc58ba6c54d126e46c391a98f6619a97c859468abb4c5c299ce14d5bd8 (56 handlers both). Loader config injected at run time. Not executed.
