Hackathon CyberChain

Grupo de Investigación BISITE

Get ready to team up, code hard, and crack some cyber puzzles at the ultimate blockchain hackathon!

Main platform: Discord. A server with channels such as #mentors, #announcements and voice stage for sessions and demos. No additional tools required.Proposed schedule: Based on CET (Madrid/Salamanca time).DEVELOPMENT CHALLENGES — CYBERSECURITY TOPICSTeams choose one of the five challenges upon registration and have the freedom to develop their proposal, adapting it as they see fit.Challenge 1 — LLM Firewall: malicious prompt detection on a black box.Build a real-time semantic filtering layer that detects malicious prompts (direct and indirect injection, jailbreak, extraction of the system prompt) by intercepting only the inputs and outputs of a black-box LLM, without access to weights or internal architecture. The only decision allowed is whether to pass or block. A high detection rate with low FPR will be valued. Dataset: labelled prompt corpus in ES/EN/AR.Challenge 2 — Threat Actor Fingerprinting: automated actor profiling from OSINTCreate a corpus of messages from social media, forums and public channels in English, Spanish and Arabic (without authorship labels), automatically identify recurring actors or campaigns by grouping by linguistic style, TTPs and shared artefacts, and generate a structured profile sheet per cluster. The challenge is not merely to classify into known categories but to discover emergent patterns. Dataset: anonymised posts with date and channel metadata.Challenge 3 — Industrial Protocol Anomalies: offline detection in Modbus/DNP3 trafficCreate an industrial traffic simulator. Classify normal traffic versus attacks (replay, fuzzing, command injection) in captures from Modbus/DNP3 industrial environments. Explainability of the anomalies will be valued. Dataset: PCAP captures with injected attacks.Challenge 4 — Autonomous Forensic Agent: from artefact to incident timelineBuild an autonomous agent (agentic-ai) that, given a forensic artefact (lightweight memory dump or reduced disk image), orchestrates analysis tools (strings, yara, process analysis), correlates findings and automatically generates an incident timeline with attack hypotheses in natural language, deciding which tool to run at each step without manual instructions.Challenge 5 — Honeypot Conversational: engaging the attacker and classifying their TTPsBuild a system that simulates being a vulnerable service (SSH panel, administration API or login form) and uses an LLM to respond convincingly to the attacker, keeping them active for as long as possible whilst automatically classifying the observed TTPs (MITRE ATT&amp;CK) and generating a session report.EVALUATION CRITERIA100 points:<ul><li>Performance on objective metrics: 30 pts.</li><li>(2) Innovation and originality: 20 pts.</li><li>(3) Code quality and reproducibility (README, verified instructions, automated testing): 20 pts.</li><li>(4) Presentation and demo: 20 pts.</li><li>(5) Real-world deployment feasibility: 10 pts.</li></ul>PARTICIPATION RULESTeams of 2 to 5 people. Code developed entirely during the hackathon; pre-trained models and open-source libraries are permitted. Use of generative AI is allowed and must be declared in the README.

Agenda

Welcome from USAL. Presentation of the challenges and setting up voice channels by teams.

Virtual Opening

Random 3-minute "Speed Networking" rooms for students from Salamanca and the Arab League to get to know each other.

Virtual Coffee Break

Development kick-off. Mentors will be available in voice rooms on demand ("Ticket system").

Coding Sprint I

It is recommended to keep a music or casual chat channel open to maintain the community spirit.

Lunch Break

Model refinement. Mentors will be available in voice rooms on demand ("Ticket system").
o	Milestone: At 15:00, a written "Elevator Pitch" (200 words) is requested in the text channel to validate the approach is correct.


Coding Sprint II

Teams upload their code to GitHub/GitLab and submit a short 2-minute video demonstrating their tool.

Project Submission

The jury streams the videos and asks questions live to the team captains.

"The Cyber-Ring"

Use of real-time voting tools (Mentimeter) for the "People's Choice Award".

Voting and Networking Final

Winners Announcement and Digital Closing Ceremony.
