Second-stage module URLs of the Foxveil/AMOS 'apph4' build, recovered from the decrypted stealer AppleScript (parent Mach-O f3b6962c49b361c63fe9d0af9a83e10a52133360117e4c8ac68272160a60edac). The script curls each to /tmp/.a_* or /tmp/.o_*, unpacks with ditto and replaces /Applications/Ledger Wallet.app from /zxc/app.zip. Recovered from the sample, not observed serving: on 2026-09-18 05:28 UTC all five answered Cloudflare 520, and no body was retrieved.
