c4ffeine

Foxveil/AMOS reflective loader Mach-O (1363536 B), first seen on YARAify 2026-10-15 02:29:04 UTC (01pemlfd, no source URL). Statically opened: its encrypted payload decodes to the same AMOS AppleScript stealer as Foxveil quill build 35b1308baa0c0a79f8431aca3988c4389c0e0f9fa3ecd4243295cd1707f53683 (57 handlers both, new obfuscation). Stealer C2 is injected at run time by an outer stage and is not in the file. Not executed.
