Field Notes

Two storage towers share a control cable carrying an amber fracture toward both systems.

Separate backup control from everyday administration

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.

A floating build tag points to an amber replacement component within a cyan software pipeline.

Mutable GitHub Actions and supply-chain risk

A workflow can execute different third-party code without any edit to your repository when an action is referenced by a movable tag. Learn the attack chain, reproduce it safely, assess the business impact, and harden the path from commit to production.

A cyan network route still reaches an abandoned platform marked by an amber beacon.

Dangling DNS and subdomain takeover

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.

Matching cyan and amber software packages sit at a branching build conveyor.

Dependency confusion in private software builds

A mixed public-and-private package configuration can let an untrusted release outrank an approved internal dependency. Learn how dependency confusion works, reproduce it safely on localhost, assess the business impact, and harden the path from source code to release.

A glowing cyan key is exposed in a glass code slab, with amber particles leaking out.

Hardcoded secrets: finding the forgotten API key

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.

A cyan envelope and ghost duplicates pass through a broken identity ring.

Email spoofing and business email compromise

Learn how email domain spoofing abuses SPF, DKIM, and DMARC gaps, what it can cost a business, how to audit it safely, and how Sunimod can help remediate the risk.
