c4ffeine

Foxveil/AMOS reflective loader Mach-O (1248512 B), first seen on YARAify 2026-10-14 00:05:04 UTC (file name sfjwmrjy, no source URL). Statically opened: its encrypted payload decodes to the same AMOS AppleScript stealer as Foxveil quill build 634472aee22bd1319f78eb025ef2bdf0e699682138b2d1b7284104443fcc0e79 (56 handlers both, new obfuscation). Stealer C2 is injected at run time by an outer stage and is not in the file. Not executed.
