What is OpenClaw and why was it hacked?

OpenClaw's an open-source Redis clustering tool; hacked via buffer overflow in failover code, exploited en masse last week.

How do I check if my OpenClaw setup was compromised?

Dump logs for 6379 traffic spikes, hunt rootkits with `rkhunter` or `chkrootkit`, rotate all service creds immediately.

If you're small-scale, yes — managed services cut vuln surface by 80%; weigh costs against breach risks.

Last week, a sysadmin's routine log check turned into panic. If you're running OpenClaw, hackers probably already own your server.
