Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 5,087,552 B), the FOUR HUNDRED AND THIRTY-FIRST payload served from https://swiftonyx16.com/f/ujkfbdvkl5i2ezacchx7ia/6b4aghms, fetched via Tor 2026-11-05 13:24:03 UTC, origin build time 13:01:55, 1 hour after the previous build (50fb938d9c86b759b589a2fa1afb84b9f18423c115abc4f1a149a19ac14f762f, built 12:01:55). Same loader family as the previous build by function-level CFG match (TLSH of __text 144, 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 1,407,306 B plaintext against 267,330 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.
