Remediation
Analysis of Unpacking the AsyncAPI npm supply chain compromise and import-time payload delivery
Immediate Containment
! Isolate compromised build environments and invalidate active developer credentials.
! Block malicious IPFS gateways and C2 network destinations identified in intelligence.
Exposure Reduction & Patching
🛡️ Enforce private npm registry proxies with package quarantine policies.
🛡️ Restrict outbound egress from CI/CD build environments to verified registries.
📦 Update affected npm dependencies to verified clean upstream releases.
Configuration & Credentials
⚙️ Enforce npm install --ignore-scripts in automated CI/CD configurations.
⚙️ Enable dependency lockfile integrity verification.
🔑 Rotate npm registry publish tokens and developer SSH keys if exposure is suspected.
Evidence Preservation
📁 Preserve package lockfiles, build logs, and memory dumps of suspicious node processes prior to remediation.
Verification & Rollback
✓ Perform automated software composition analysis (SCA) scans across all active branches.
↩️ Rollback: Revert to prior known-good package version pins in repository manifest files.
