Episode notes
Real Attacks from Abandoned IT
- The Hazy Hawk threat actor hijacked global DNS by exploiting dead cloud endpoints linked via CNAME records.
- Similarly, Watchtower researchers found abandoned S3 buckets leading to supply chain compromises for major organizations.

- Abandoned or unused IT resources represent a form of technical debt that can immediately expose risk.
- This debt must be addressed continuously, as it exists the moment code ships.
Automate Regular IT Cleanup
- Regularly sweep DNS records and other external resources for abandonment and clean them up promptly.
- Automate cleanup processes where possible to catch unused resources early.
