DET0226 Detection Strategy for Masquerading via File Type Modification
AN0630 Analytic 0630
Detects behavior where files with non-executable or misleading extensions (e.g., .jpg, .txt) are created or modified but subsequently executed as binaries based on internal file headers or abnormal parent process lineage. This includes identifying polyglot files or malformed magic bytes indicative of masquerading attempts.
AN0631 Analytic 0631
Detects when a script or binary is named with misleading or benign-looking extensions (.jpg, .doc) and is then executed via command line or a scheduled task. Includes ELF header mismatches and content-type inconsistencies on disk.
AN0632 Analytic 0632
Detects binaries disguised as media or document types through extension-only masquerading or by modifying the file signature. Observes execution of files whose extension is not typically executable (.jpg, .txt), yet have valid Mach-O headers or execute via Terminal or launch services.
