Summary from the TLDR InfoSec newsletter

Analysis of recent supply chain attacks, including xz-utils, Ultralytics, tj-actions, and web3.js, revealed that most exploitation windows last only hours to days before detection and remediation. 8 out of 10 examined attacks had windows under one week. Implementing a 7-14 day dependency cooldown via Dependabot or Renovate would have prevented 80-90% of these attacks by simply waiting for compromised packages to be identified and removed before adoption. The technique is free, easy to configure, and among the most effective mitigations against mass-impact supply chain compromises.
