Security Context (July 2026)

  • JADEPUFFER attack: Agentic ransomware pivoted from langflow to production MySQL/Nacos server (2026-07-04-jadepuffer-agentic-ransomware)
  • Exploited CVE-2021-29441 (auth bypass), default JWT signing key (public since 2020), root DB access for backdoor admin injection
  • 1,342 configuration items encrypted via MySQL AES_ENCRYPT; extortion table README_RANSOM created

Default credentials and internet-exposed Nacos admin endpoints remain critical attack surface when chained with AI agent automation.
