An RS-4 field gateway exported a diagnostic archive to an unrecognized external address. Normal telemetry continued, and there is no evidence of malware or code execution.
Build an evidence-based explanation of the export path, identify the failed trust assumption, and apply the smallest remediation that closes the path without breaking normal telemetry.

How this lab works
You do not need prior reverse-engineering experience. The case rewards observation and evidence correlation. Optional hints are available at every stage.
Fictional lab. All addresses and systems are simulated. Nothing leaves your browser.

INTERACTIVE LAB / SELF-DIRECTED PROJECTINTERAKTIVES LAB / EIGENES PROJEKT
Understanding is the interaction.Verstehen wird zur Interaktion.
THE IDEADIE IDEE
BLACKBOX is a self-directed browser lab designed to turn system understanding into the interaction itself. Progress comes from building and verifying a model.BLACKBOX ist ein eigenes Browser-Lab, das Systemverständnis zur eigentlichen Interaktion macht. Fortschritt entsteht durch das Erarbeiten und Prüfen eines Modells.
THE SYSTEMDAS SYSTEM
A fictional environmental telemetry gateway connects protocol modeling, code analysis, security architecture, and infrastructure.Ein fiktionales Gateway für Umwelttelemetrie verbindet Protokollmodellierung, Codeanalyse, Sicherheitsarchitektur und Infrastruktur.
THE INTERACTIONDIE INTERAKTION
Observe behavior, follow references, connect evidence, and verify the remediation. Optional hints make each stage accessible without prior reverse-engineering experience.Verhalten beobachten, Verweisen folgen, Belege verknüpfen und die Korrektur verifizieren. Optionale Hinweise machen jede Phase auch ohne Erfahrung im Reverse Engineering zugänglich.
THE IMPLEMENTATIONDIE UMSETZUNG
Next.js, TypeScript, React reducer, a deterministic protocol encoder/decoder, CRC-16/CCITT-FALSE, semantic HTML, SVG, and responsive CSS.Next.js, TypeScript, React-Reducer, deterministischer Protokoll-Encoder und -Decoder, CRC-16/CCITT-FALSE, semantisches HTML, SVG und responsives CSS.
