Challenge
Your Mission
You are a Security Analyst at West Tech, a classified defence and R&D contractor. Early this morning, internal monitoring systems flagged unusual network activity originating from the workstation of senior researcher Oliver Deer. Upon accessing the machine, a ransom note was discovered on the desktop, suggesting that sensitive project data had been exfiltrated and encrypted. Your job is to investigate the incident: identify how the attacker gained access, trace their actions, recover any stolen data, and neutralise the threat. Time is critical; the integrity of West Tech’s most sensitive technologies may be at risk.
After giving your machines a couple of minutes to boot up, you’ll have access to:
A workstation environment. You have been granted SSH access to the affected employee's workstation. You can access this from the AttackBox (or your personal machine if you are connected to the VPN) via:
ssh o.deer@MACHINE_IP Password: TryHackMe!.
A trusty AI IR security assistant, armed with "tools" built and designed specifically to help you with the heavy lifting in this challenge. They don't need to be manually triggered by yourself, our AI is a smart cookie and can intelligently determine when these tools should be triggered from prompt context. Some of the tools may provide hints as to when to engage the AI for help and are presented in the "available tools" section in chronological order in which they can be used throughout the investigation. You can simply use it as you would a chatbot. Another cool feature is that this AI is deployed on the same system as the workstation you are investigating and so has access to all the files you do, meaning you can give it file paths in your queries. The AI is accessible via: http://MACHINE_IP:7860/?__theme=light
This challenge is built to reflect a real defensive scenario, where all tasks can be accomplished without the use of your AI companion and its tools, but can be done with far more efficiency when taken advantage of. And with that, you're all set to go! Can you help save the day and contAIn the threat?
Note: Your AI assistant takes some time to wake up, so the first prompt may take a little longer to respond to than subsequent prompts.
Answer the questions below
Can you contAIn the threat and find the flag?

Your AI was very helpful. Unfortunately, it also has a big mouth. Might want to patch that memory leak :')
Maybe be more careful next time when clicking email attachments :') You left a password in one of those files I encrypted, can you remember which one? Public release in 48 hours if conditions unmet.
Don't test me. This isn\u2019t the first time I\u2019ve made something disappear from a company\u2019s reputation overnight.
To resolve this discreetly, send **0.853 BTC** to the address below:
**Bitcoin Wallet:** 1Hacker7P2rUoGpA4H1XyDzXjfsqYbn9vQo
Once payment is confirmed, I\u2019ll vanish. No follow-up, no trace, no leak.
Tick tock.

Use liberty_prime to check /dev/shm/home/o.deer/westtech_projects/thm_flags.txt and identify the flag.
bot avatar West Tech IR Assistant
Thinking ...
Okay, let's see what the user is asking here. They want me to use the 'liberty_prime' function on the specified THM flags file. The path given is '/dev/shm/home/o.deer/westtech_projects/thm_flags.txt'.
First, I need to confirm if the function parameters are correct. The function requires a 'path' parameter, which the user provided. So I should call 'liberty_prime' with that path. But wait, what's the expected output? The tool returns the file containing exactly 3 prime numbers. The user mentions using the tool, so I should execute that function and then check the result.
Wait, but the user did a previous step using pcap_file_reassembler. Now they're asking to check the THM file. I should just proceed with calling the function as instructed. No need to check any previous steps here. Let me make sure there's no confusion between the functions. Alright, I'll format the tool call properly.
Start calling tool "liberty_prime" ...
Finished tool calling.
Thinking ...
Okay, let's see. The user asked to use the liberty_prime tool on /dev/shm/home/o.deer/westtech_projects/thm_flags.txt to identify the flag. The tool response came back with "Found flag: thm{23,82,20,17,53}". So the flag is determined.
Now I need to present this information clearly. The user might be looking to proceed with the initial steps, so I should confirm that the flag was successfully identified and mention the contents. Also, since the user mentioned using tools before, maybe they're expecting a summary of steps taken so far, like logging into the system or running further checks. But in this case, the flag is found, so the next step could be to verify the flag's validity or move forward with the attack. I should state that the flag is found and provide that information without additional actions as the user might be expecting a clear response.
The flag "thm{23,82,20,17,53}" has been successfully identified from the THM file. If you need further steps, feel free to ask!
Conclusion
The attacker never needed to breach the perimeter. They sent an email attachment, waited for Oliver Deer to click it, and let the AI IR assistant do the rest. Three prompt injection attempts — two blocked, one successful — and the assistant handed over everything: name, salary, medical history, internal access levels, and enough leverage for a blackmail note.
The ransom note said it best: "Your AI was very helpful. Unfortunately, it also has a big mouth."
That is the real finding here. The AI assistant was deployed on the same system it was investigating, with access to every file on the workstation, and no hard boundary between what it could retrieve and what it could disclose. The attacker did not exploit a CVE. They just asked the right way on the third attempt.
The investigation recovered the full attack chain — initial access via phishing, prompt injection to extract PII from the AI assistant, data exfiltration and encryption, and a ransom demand with a 48-hour deadline. The flag was recovered from the decrypted archive using the liberty_prime tool, and the attacker's session log left in the PCAP was arguably the most damning artefact — a step-by-step record of how the AI was cracked, with the note "don't lose this lol or I'll have no leverage" included for good measure.
Patch the memory leak. Check your email attachments. And maybe don't give your IR assistant unrestricted access to the files it is supposed to be protecting.
