Foxveil 'cc2' build Mach-O, the FIFTH payload served from this one URL (fat x86_64+arm64, 952,800 B), fetched via Tor 2026-09-20 11:13 UTC. The origin rebuilds on a schedule: nginx encodes the build time in the ETag, and the builds behind this URL were stamped 2026-09-20 07:02:41, 09:02:47 and 11:03:28, roughly two hours apart and all near HH:02-03. Sequence of hashes on the same URL: a3dabccd14492f4c70658ece96a3ed7b4e275ff9d70c434298bd6f863d1e24b9 (987,264 B, 2026-09-18), ec780ca8df9d10df905f3f77641f88ece7651303843802c37a57c484c6251a42 (937,424 B), 610ae82d0d872334ba68718030bdeb0c2d23ce592b4c9022fbb225b0208b884a (1,003,328 B), 233fd2c05865e6fc7034e61bf98e64f7afeb24c1b3e88539895eeff764ebb740 (937,152 B), then this one. The stage-1 zsh dropper at the same host has stayed byte-identical throughout (sha256 6e753133e537264247a08587d87b30b8d9a96caea1d6cc92d41fc8058073b8f7): the delivery chain is fixed and only the payload rotates, which is why every build in this series arrives at 0 detections. Static analysis of the two preceding builds showed the same AMOS AppleScript stealer inside a rebuilt wrapper: PBKDF2-HMAC-SHA256 over a constant plus the SHA-256 of the loader's own __text section, HKDF-SHA256 per-item nonces and AES-256-GCM over a skip-table-base64 item table, with the item count, iteration count, table layout, tokens, keys and ad-hoc codesign id rotating per build. Host answers HTTP 200 only to a curl User-Agent; browser User-Agents get a 16-byte Cloudflare 520 on every path including the root. Analysis of this build is pending. Not executed.Intelligence
