chaos-engineer

This fragment provides chaos-testing examples that intentionally stress resources, disrupt selected containers and networking, modify `/etc/hosts`, and generate an expired test certificate. These actions can cause outages if run outside an isolated, authorized test environment; the DNS helper also risks command injection if its domain argument is untrusted. It contains no evident credential theft or covert exfiltration, so malware likelihood is low, while operational security risk is material. The example domain is api[.]external-service[.]com.
