Foxveil loader (Cato CTRL name), 'kis' build, fetched live over Tor 2026-09-19 from forgewillow.com. The host is served by Cloudflare and gates on User-Agent: a plain curl/8.7.1 receives this 937424 B Mach-O, while a Safari User-Agent receives a 16 B Cloudflare 520 - the same browser-gating seen on blueprint-71.com. forgewillow.com was registered 2026-09-14 at Dominet (HK) Limited, one day before the stage-1 build that names it. The host was recovered statically, not by scanning: the 2026-09-15 Foxveil stage-1 zsh dropper (sha256 ab9dd07884af5e249ab241e468da756bf3e6dcb2aea061d0e656d3812484256e) is the self-keyed const-key variant and decrypts offline - _kb = len("weekly")*202 + len("weekly")%12 + 12 = 1230, key = md5("1230") = 4122cb13c7a474c1976c9706ae36521d, AES-128-CTR with a zero IV over the hex concat of _feature_flags/_cache_seed/_license_salt/_rollout_key (_probe_salt is a decoy and must be left out), then gunzip to a 1220 B stage-2 zsh (sha256 105763aed0f3d1f847475748eca2ca2ee1b07c7a6a4c11c5ade0fa9769535795). That stage-2 beacons to lyric-8.com /api/metrics/run and downloads this payload to /tmp/.tmcxpkr89, strips the quarantine attribute and chmods it. The '/kis/' subpath is new; the path token 2kqYRM0D... is the same one seen on earlier Foxveil rotations. Differs from the 2026-09-18 'apph4' build (sha256 a3dabccd1449...): 987264 -> 937424 B, both embedded payload blobs slightly smaller, both LC_UUIDs changed. Not yet unpacked - attribution here rests on the stage-2 decode and the delivery path, not on an independent body fingerprint; forgewillow.com does NOT serve the forged 139 B 404 seen on other Foxveil hosts. Fetched over Tor; never executed.
