Foxveil/AMOS reflective loader Mach-O (2,020,304 B) served at https://swiftonyx16.com/f/ujkfbdvkl5i2ezacchx7ia/6b4aghms on 2026-10-20 17:23 UTC to a curl User-Agent only (browsers get a Cloudflare 520), fetched via Tor; URL named in the decoded stage-2 of the same host's stage-1 zsh (04d13a31). Statically checked against the current quill build: same loader code shape, payload opens with the known key schedule, kept stealer payload within 1% in size, config injected at run time. Not executed.
