🤖 AI Security Takes the Stage at BSides Luxembourg 2026

“XCTDH Cross-Chain Transaction Data Hiding: Cyber Espionage and OPSEC Encounters” – Ellis Stannard
Talk (40 minutes)

Uncover a cutting-edge 40-minute talk revealing how attackers are leveraging blockchain ecosystems to build resilient and stealthy command-and-control infrastructure. This session introduces Cross-Chain Transaction Data Hiding (XCTDH), a novel technique that uses multiple blockchains to store and deliver malicious payloads—blending seamlessly with legitimate cryptocurrency activity and making detection extremely challenging.

Through a real-world investigation, the talk walks through the full attack chain—from social engineering and weaponized repositories to multi-stage payload delivery and evasion of modern defenses. Attendees will gain insight into how low-cost, decentralized infrastructure is reshaping cyber espionage, along with the broader implications for detection, attribution, and defensive strategy.

Ellis Stannard is a security researcher and core member of the Ransom-ISAC initiative, contributing to collaborative threat intelligence efforts focused on ransomware and advanced persistent threat campaigns.
