Foxveil 'nuyar' build Mach-O, the NINETY-FOURTH payload served from this one unchanged URL (fat x86_64+arm64, 1,873,504 B), fetched via Tor 2026-10-30 00:06:36 UTC, origin build time 00:02:08, 1 hour after the previous build. The origin is nginx, so each build time is readable from the ETag: the payloads served behind this URL were stamped 2026-10-26 01:02:02, 02:02:08, 03:02:02, 04:02:09, 05:02:02, 06:02:08, 07:02:03, 08:02:09, 09:02:01, 10:02:09, 11:02:00, 12:02:08, 13:02:03, 14:02:09, 15:02:03, 16:02:09, 17:02:04, 18:02:08, 19:02:03, 20:02:07, 21:02:01, 22:02:09, 23:02:04, 2026-10-27 00:02:07, 2026-10-28 00:02:10, 2026-10-29 00:02:07 and 2026-10-30 00:02:08 UTC. The job skips hours rather than running on a fixed interval, and the gaps measured so far run from 58 minutes to 1 hour 59 minutes.

The stage-1 dropper on this host is not on our watch list, so only the payload URL is measured. The first build in the series was unpacked statically and held the same AMOS AppleScript stealer, with the same 47 handlers, hosts and persistence, decrypted with a key derived from the SHA-256 of the loader's own __text section, so each repack rekeys itself. What rotates is the wrapper: obfuscation volume, PBKDF2 iteration count, encrypted item count and table layout, tokens and the ad-hoc code signing identity. This build compared against the previous one: 45 __text functions against 47, TLSH of __text 167, above the 11 to 128 range measured between earlier builds of this family, while the per-function CFG match still reads repack-like. The encrypted payload table holds 93 items totalling 267,876 bytes of plaintext against 98 items and 265,712 bytes in the previous build, a 0.8 percent move: the same script re-chunked. This build was not unpacked. Host answers HTTP 200 only to a curl User-Agent; browser User-Agents get a Cloudflare 520. Not executed.
