Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 5,924,016 B), the TWO HUNDRED AND TWENTY-SEVENTH payload served from https://chant66.com/f/nt5ax1_btyoxzizb9whm9q/nuyar9lb, fetched via Tor 2026-11-05 13:23:15 UTC, origin build time 13:02:07, 59 minutes after the previous build (a6165d904c5a3d33890f510cf0afdbbd8f4a9bc966eb08be10be29bf5897da72, built 12:02:08). Same loader family as the previous build by function-level CFG match (TLSH of __text 186, 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 1,377,264 B plaintext against 264,852 B, but the wrapper moved with this build: Fleet-wide 13:00 rebuild added one unreferenced random base62 string literal of about 1 MB to the compiled payload; it accounts for the whole size growth and is filler. Same stealer as the previous build, 57 handlers, same literal multiset apart from random identifiers, same path set, env-injected config, no hosts in the sample. Not executed.
