Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 6,038,816 B), the FOUR HUNDRED AND THIRTY-FIRST payload served from https://nova-75.com/f/vrhqljbnscwhbyhltuwmsq/t2990cmj, fetched via Tor 2026-11-05 13:23:22 UTC, origin build time 13:02:01, 59 minutes after the previous build (b058d67154f5b8785474c2bdf35b6f9377ce53d019a957004600849f625f94d8, built 12:02:04). Same loader family as the previous build by function-level CFG match (TLSH of __text 217, 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 1,501,644 B plaintext against 263,778 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.
