Marc — Security Researcher

Security researcher and engineer specializing in DeFi protocol security, onchain threat detection, and adversarial research. Currently securing one of the largest DeFi protocols by TVL.

DeFi Protocol Security

I design and operate multi-layer security architectures for Web3 environments where a single exploited vulnerability can result in nine-figure losses. This includes custom onchain invariant monitoring, behavioural anomaly detection, and formal security modeling for smart contract protocols.

Adversarial Research

I research real-world threat actors targeting the crypto space — including nation-state groups like BlueNoroff (Lazarus Group / DPRK) that actively target DeFi protocols for financial theft. My work focuses on behavioural analysis and translating findings into high-fidelity detection engineering rather than indicator-based defences that age quickly.

Detection Engineering

I build detection logic in SIEM platforms (Sumo Logic) and EDR (CrowdStrike) that surfaces real threats — correlating onchain signals with infrastructure telemetry to distinguish genuine exploit activity from noise.
