Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 1,971,168 B) served to a curl User-Agent at https://frame-kite.com/f/rjcf4ggdrb1wp5syzplnda/5r7r2qc0, fetched via Tor 2026-10-17 10:22 UTC. Log-collector loader generation (masked base64 decode table, never-called filler functions). Statically opened: the payload decodes to the same AMOS AppleScript stealer as the current Foxveil builds (57 handlers); stealer C2 injected at run time, not in the file. New delivery host frame-kite.com. Not executed.
