Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 5,053,728 B), the FIVE HUNDRED AND ELEVENTH payload served from https://willow-13.com/f/4nsri1yksbqlneewnevynq/cvfo3thd, fetched via Tor 2026-11-07 08:07:44 UTC, origin build time 08:05:32, 1 hour after the previous build (1f9ab3287262235f2592e1d4a0a0459c7d4640ff03ecc7a540433cf3807c551c). Same loader family as the previous build (44 __text functions against 47, TLSH of __text 203, above the 11 to 128 band measured between earlier builds of this family, while the per-function CFG match still reads repack-like) and a payload table of 262,878 B plaintext against 263,720 B: a scheduled repack of the same AMOS stealer. Not executed. Today's build of this series on MalwareBazaar: https://bazaar.abuse.ch/sample/1f9ab3287262235f2592e1d4a0a0459c7d4640ff03ecc7a540433cf3807c551c/
