Detects execution, chmod, or invocation of the fuckaliyun.sh script used to disable Alibaba Cloud's Cloud Shield/Yundun host security monitoring agent, plus the associated iptables install added by JadeProx's modified variant of the script. Requires an actual execution context (direct invocation, chmod +x, or a bash/sh interpreter with the script as an argument or parent process) rather than any incidental string reference to 'fuckaliyun'.
