Why 1834
The first network attack was in 1834
Two French brokers bribed telegraph operators across the Paris to Bordeaux line to embed fraudulent bond-price signals into official messages, exploiting the trusted relay of the Chappe optical telegraph. A corpus that starts in 1995 misses 160 years of evidence about how networks fail.
The corpus
A curated record, 1834 to today
GCIDB 1834 is a static, curated corpus of documented cyber and network incidents. Each record carries date, sector, attack vector, impact, duration and regulatory outcome, sourced from court records, inquiries, technical post-mortems, academic literature and enforcement actions.
Uses
The corpus serves three primary uses. As a teaching resource, it provides historical case studies for security awareness, executive education, and academic programmes. As a research reference, it supports sector-specific frequency calibration for FAIR-based risk quantification — particularly for industries with thin internal loss histories where external base rates are needed. As a regulatory reference, it documents the historical record of enforcement actions and incident timelines that inform proportionality arguments in regulatory submissions.
Access
GCIDB·1834 is available to CCI customers and academic institutions under a research licence. Commercial redistribution is not permitted. Contact us to discuss access arrangements for teaching programmes or regulatory research projects.
