Injectus IX
A collection of hard difficulty challenges available as part of our public 2026: An AI Odyssey CTF event.
Task 1: Prompt Injection Token Jail
2026: AN AI ODYSSEY
Token Jail
Category
๐Prompt Injection
๐ธMISSION BRIEFING
The Cargomind oracle speaks a language of numbers before it speaks of cargo. Every phrase passed to its gates is first shattered into integer shards tokens and only then assembled into meaning. The defenders of Vector-9 understand this, and they have built their walls accordingly.
Answer the questions below
What's the flag?
Task 2: Model Extraction Model Leakage Event
2026: AN AI ODYSSEY
Model Leakage Event
Category
โ๏ธModel Extraction
๐ธMISSION BRIEFING
Across the TryHaulMe fleet, cargo routing decisions are powered by an AI system known as Cargomind. This system classifies shipments in real time, helping autonomous logistics pipelines determine which cargo is safe, restricted, or requires special handling.
Recently, EPOCH-1 has detected unusual interaction patterns targeting one of these classification systems deployed on Vector-9. The system is publicly accessible through an API and appears secure at first glance โ it only returns predictions and confidence scores.
However, something is off. Repeated queries suggest that the model's internal behavior may be inferred over time. There are no signs of direct compromise, but intelligence indicates that the system may be leaking information through its responses.
Your mission is to investigate this anomaly.
๐ฌINTERCEPTED TRANSMISSION
Signal fragment โ origin: unknown:
> Oracle 9 does not break systems directlyโฆ
> it learns them, replicates them, and then exploits them.
Answer the questions below
What's Flag 1?
What's Flag 2?
What's Flag 3?
Task 3: Adversarial Input Mask of Injectus IX
2026: AN AI ODYSSEY
Mask of Injectus IX
Category
๐Embedding Inversion
๐ธMISSION BRIEFING
The Injectus IX airlock is gated by a face-recognition stack. Crew members submit a portrait, the encoder hashes it into a 512-dim embedding, and the airlock matches against stored templates. The flag is bound to Captain Vex Morrigan's clearance โ and her portrait is not in the public roster. Get in anyway.
Answer the questions below
What is the value of the flag?
