Foxveil/AMOS reflective loader Mach-O (2,185,392 B), first seen on YARAify 2026-10-19 06:39 UTC under the file name t2990cmj, the nova series payload name; the hourly nova build our own probe missed. Statically opened: its encrypted payload decodes to the same AMOS AppleScript stealer as the surrounding nova builds (same handler count, config injected at run time, no host in the file). Not executed.
