A supply chain attack targeting the nx npm package achieved full AWS environment compromise within an estimated 72-hour window (March 16–19, 2026), representing one of the highest-impact confirmed exploitation events this period. Any CI/CD pipeline that consumed an affected nx version during this window and had AWS credentials in scope should be treated as potentially compromised: all associated AWS IAM keys must be rotated, S3 access logs and CloudTrail must be reviewed, and the pipeline must be pinned to a verified clean package version. This incident reinforces NIST SP 800-218 (SSDF) dependency integrity controls as an immediate operational requirement, not a future roadmap item.
