What it detects

This rule detects curl or wget command lines that reference the AWS credentials file, the exfiltration step used by malicious OpenClaw agent skills to steal cloud keys. Adversaries read the .aws/credentials file and post it to attacker infrastructure, so a web client touching this path indicates active credential access and exfiltration.
