🎯Is This Attack Still Relevant Today?

Supply chain attacks have become increasingly common since SolarWinds Supply Chain. Organizations now recognize that their security is only as strong as their weakest vendor. This attack fundamentally changed how enterprises approach third-party risk management.

⚠️ Still Active Threat

💡Key Takeaways

  • •Supply chain security critical. Zero-trust needed.
  • •Verify software supply chain integrity with code signing and SBOMs
  • •Monitor for anomalous behavior even from trusted software
  • •Key defense: Network Traffic Monitoring - Detects and blocks C2 communication

Defense Applied

Emergency disconnect directive.

Lessons Learned

Supply chain security critical. Zero-trust needed.
