Mercator

Mercator was part of hackathon.lu 2026, organised by CIRCL on April 14th and 15th in Luxembourg. This annual event brings together developers and practitioners around concrete open-source cybersecurity projects — exactly where Mercator belongs. Over two days, we built and integrated a connector between Mercator and CPE Guesser, the CIRCL tool that automatically identifies CPE identifiers from a software component’s name and version. A missing link between application inventory and vulnerability exposure.

Excellent lessons learned from David Savary (University of Tours) on an often overlooked topic: the resilience of the application mapping itself. When the network goes down, that’s precisely when the mapping becomes critical… and yet often inaccessible. The solution presented is simple, pragmatic, and effective: automated Mercator exports, enriched by queries, stored offline via Nextcloud, and directly aligned with the institution’s Disaster Recovery Plan (DRP). Result: an operational mapping in a crisis situation, usable even without a functional IT system. This is exactly what we expect from a mature security approach. ...
