Foxveil/AMOS reflective loader Mach-O (fat x86_64+arm64, 1,872,960 B), the SECOND payload served from https://cube-60.com/f/3ouaaio6tobacvyfqoejza/sul9ec1i, fetched via Tor 2026-11-04 11:11:48 UTC, origin build time 11:02:44, 1 hour 59 minutes after the previous build (2bc2b4e876d2fd2ba905b5d82871e09ffb83097d40f9eb1bffc9a8ff1b73ef22, built 09:02:45). Same loader family as the previous build by function-level CFG match (TLSH of __text 193, 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 259,526 B plaintext against 268,892 B, but the wrapper moved with this build: Rebuilt wrapper with new PBKDF2 count 97439, 85 items of which 8 filler, rotated cfg env-var names, and a 3.48 percent smaller compiled payload from lower obfuscation volume. Same stealer as cube build 1 and quill 762, 57 handlers on all three, statement similarity 0.89, literals equal apart from rotated names, identical path set, no hosts in the sample. Not executed.
