bashbash

bash is a Unix living-off-the-land binary catalogued by the GTFOBins. Documented abuse functions: download, file-read, file-write, library-load, reverse-shell, shell, upload. Mapped ATT&CK techniques (per LOLBAS / GTFOBins → MITRE crosswalk): T1005, T1059, T1071, T1105, T1565, T1567. Defenders should monitor execution of bash under non-administrative or sudo contexts and alert when its arguments match the abuse-function signatures.
