c4ffeine

Foxveil/AMOS reflective loader Mach-O (1478096 B), first seen on YARAify 2026-10-15 00:25:03 UTC (sfjwmrjy, no source URL). Statically opened: its encrypted payload decodes to the same AMOS AppleScript stealer as Foxveil quill build f3d8ed915b2a53a35e52bd1ec39c21deeaa831ae0a969221bb7bab492938ff60 (57 handlers both, new obfuscation). Stealer C2 is injected at run time by an outer stage and is not in the file. Not executed.
