Field Notes by Christopher Jacobson

A backup can complete every night and still fail when the same compromised account can erase production, recovery copies, retention settings, or encryption keys. Learn the attack chain, run a safe local demonstration, and design a tested recovery boundary that survives loss of production control.

Deleting a hosted service without removing its DNS record can leave a trusted company subdomain pointing at a resource another party may be able to claim. Learn the attack chain, run a safe localhost demonstration, assess the business impact, and build a disciplined offboarding process.

A single API key committed to source code can expose customer data, create fraudulent cloud costs, interrupt operations, and give an intruder a path into connected systems. Learn how the weakness works, reproduce it safely in a local lab, and fix it at the code, hosting, and process levels.
