Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 6,153,408 B), the FOUR HUNDRED AND SIXTY-EIGHTH payload served from https://willow-13.com/f/4nsri1yksbqlneewnevynq/cvfo3thd, fetched via Tor 2026-11-05 13:22:30 UTC, origin build time 13:05:30, 59 minutes after the previous build (de6ce5b552cafb9066c048849623c39e024d43fe9580a8e81947dbe4e97972bd, built 12:05:34). Same loader family as the previous build by function-level CFG match (TLSH of __text 66, inside the 11 to 128 band measured between builds of this family) and a payload table of 1,436,382 B plaintext against 263,752 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.
