The command the identifier reads trips no Sigma process-creation rule. This command is 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 ghc. The identifier reads the line that runs ghc.
