Security, resilience, and adversarial measurement for web3, P2P networks, and distributed infrastructure.
Examines how streaming fragmentation relates to earlier leaks, larger torrent swarms, and increased user risk in piracy ecosystems.
We audit large companies' privacy and data sharing practices through email marketing. The study reveals systematic data sharing with third parties and evaluates implications for user privacy.
Presents EtherBee, a global-scale dataset coupling Ethereum node performance measurements with honeypot interactions and full network sessions. Enables research on blockchain infrastructure security and performance.
Presents initial evidence of widespread, systematic reconnaissance targeting Ethereum node infrastructure. Measurement data reveals that blockchain nodes face pervasive scanning and probing from adversarial actors.
Introduces MagnetDB, a 15-year longitudinal torrent-discovery dataset (4,936,257 magnet links) matched with IMDb metadata, enabling reproducible research on piracy dynamics, release timing, and P2P behavior.
Funded research to build real-time surveillance and changepoint-based anomaly detection for Ethereum peer-to-peer network security.
Funded design and evaluation of an overlay networking approach to improve Ethereum node anonymity and resilience against network-layer targeting.
Presents NinjaDoH, a moving-target DNS-over-HTTPS architecture that combines hyperscaler deployment with IPNS-based endpoint agility to improve censorship resistance and availability.
Funded work on RADS: Rapid Activation via Decentralized Snapshots, a decentralized storage pipeline for Ethereum snapshot delivery and recovery.
Captures migration governance decisions for Helium's transition from a sovereign Layer-1 blockchain to Solana, including Readiness Working Group timing decisions in March-April 2023.
We propose a zero-trust validator deployment mechanism for proof-of-stake networks using NFTs and smart contracts. The approach enables programmable, transferable validator identity without trusting central authorities.
