We don't just build.
We publish.
We're a RIPE NCC member and MANRS participant. We've helped INTERPOL with network investigations, compared notes on RPKI and BGP routing security with Fraunhofer SIT and Tsinghua, and open-sourced our own security tools. Here's some of that work.
PDF Prompt Injection Toolkit
An open-source security research toolkit for detecting and mitigating prompt injection attacks embedded within PDF documents targeting LLM-based pipelines.
OpenHuizeBox — Privacy-Audit Research VM
An open-source research VM built on VirtualBox. Software fingerprints a machine by its hardware (CPU, disk serials, firmware tables, network cards); OpenHuizeBox takes those values and makes them something you can see and change. Built for privacy research and malware analysis.
RIPE NCC General Meeting — Policy Discussion & Governance
Participated in RIPE NCC General Meeting, contributing to discussions on RIPE policy development and governance processes affecting LIR members and the broader Internet routing ecosystem.
RPKI & BGP Hijack Prediction — Technical Discussions
Contributed ideas and exchanged insights on RPKI deployment and BGP hijack prediction with researchers at Fraunhofer SIT and Tsinghua University.
Assisting INTERPOL Network Investigations
Provided technical consultation on passive DNS analysis and IP attribution to assist law enforcement in tracing cross-border cybercrime infrastructure.
