Release the RAVEN: Data Heist and Persistence

August 14, 2026 · LevelBlue SpiderLabs · Severity: HIGH

This article details the post-exploitation phase of a simulated attack on a Kibana and Elasticsearch environment, demonstrating data exfiltration and persistence techniques. After gaining initial access through exposed ports and exploiting known vulnerabilities, the attackers show how they maintain access and steal data. The piece underscores the importance of securing configuration management tools and monitoring for lateral movement.

We have access through port 9200. We have code execution through port 5601. Reconnaissance is complete, CVEs have been exploited, and Kibana has been compromised. Over the past three posts, we proved that we could get in. Now we prove what happens after.

Key Takeaways

  • Attackers demonstrate persistence and data theft after compromising Kibana.
  • Exploiting exposed ports 9200 and 5601 enables initial access and code execution.
  • Securing Elasticsearch and Kibana configurations is critical to prevent post-exploitation.
