curlcurl

curl is a Unix living-off-the-land binary catalogued by the GTFOBins. Documented abuse functions: download, file-read, file-write, library-load, upload. Mapped ATT&CK techniques (per LOLBAS / GTFOBins → MITRE crosswalk): T1005, T1105, T1565, T1567, T1574. Defenders should monitor execution of curl under non-administrative or sudo contexts and alert when its arguments match the abuse-function signatures.
