DET0281 Detection Strategy for Compressed Payload Creation and Execution
AN0782 Analytic 0782
Monitors for compression tool usage (e.g., 7zip, WinRAR, MakeCab) that follows or precedes file modification, suspicious file types (e.g., .exe, .dll) being compressed, or dropped from self-extracting archives followed by immediate execution.
AN0783 Analytic 0783
Detects sequential command-line compression utilities (e.g., gzip, tar, zip, 7z) followed by execution of unpacked files, especially in temp directories or under non-standard locations like /dev/shm or /tmp with ELF binaries.
AN0784 Analytic 0784
Identifies archive utilities (e.g., ditto, unzip, xar, pkgutil) used to extract payloads to non-standard paths, then correlates with execution or file permission changes (e.g., `chmod +x`) and process spawns from decompressed location.

Threat actor context
These are explicit actor-to-technique associations in the existing Threat Matrix snapshot, not attribution of an event or proof that a detector identifies the actor. No tool-to-actor relationship is inferred.
