FEBRUARY CRYPTO TRACING CHALLENGE IS LIVE

https://www.linkedin.com/feed/update/urn:li:activity:7429049397344100352/

For those just starting on their crypto investigations journey, here are three tools I would recommend:

1️⃣ Arkham Intelligence - Great free tool! However, there are levels to using it from basic to advanced. There are some neat tricks to learn on this tool to get the best out of it.

2️⃣ SPECTRA - The all-seeing eye... this is a tool belonging to Intelligence On Chain (IOC) and it has multiple modules to help you find the information you're looking for.

3️⃣ Obsidian - Free and locally hosted! This tool is one of the best note-taking apps out there, in my opinion. I've literally used it to map out hundreds of millions of dollars worth of scams

Links are below: ⬇️


Arkham - https://intel.arkm.com

Spectra - https://spectra.intelligenceonchain.com 100% FREE until 28th Feb - use code SPECTRA1 on the basic level

Obsidian - https://obsidian.md

A message in my DMs stopped me in my tracks. 🛑
Not because it was complicated…
But because it exposed something most investigators never talk about.

Many of the people in my network - investigators, law enforcement professionals, lawyers, and forensic accountants - rely on extremely expensive investigative tools. 💵 💵

And to be clear: those tools absolutely have their place, especially when evidence needs to stand up in court. 🧑‍⚖️

But here’s the uncomfortable truth…
A huge number of investigations could be run using free or very low-cost tools - if you simply knew how.

Lower tool costs = lower overhead.
Lower overhead = lower cost to the client/victim

So I’m considering building something practical:
A step-by-step course that walks through a real investigation, showing exactly how to execute it using free or low-cost tools.

A purely practical course!

But I’ll only build it if there’s genuine interest. Here's what to do

1️⃣ If 100 people raise their hands, I’ll build it. If that sounds useful, please let me know by completing the form below

2️⃣ And feel free to discuss in ⁠💬┃general-chat

MOST PEOPLE THINK SCAMS ARE OBVIOUS.
They’re not!

I sat down with Jesse Gossman - an 18-year Detective specialising in economic crime - and what he revealed about crypto-related crime is honestly eye-opening.

We talk about:
🔍 The early days of crypto crime (and how unprepared everyone was)
💰 What really goes on inside $1M+ cases
🧠 The psychology behind social engineering
🚨 Why today’s scammers are more calculated than ever

TRACING CRYPTO LAUNDERING NETWORKS: A PRACTICAL CASE STUDY

We’ve just released the latest Crypto Tracing Challenge solution, focused on identifying and deconstructing a laundering network operating through privacy infrastructure.

This case study demonstrates how two seemingly isolated transactions can be used as entry points to uncover a broader laundering ecosystem. By applying structured tracing methodologies, it becomes possible to map flows across multiple layers, including mixers and automated exchange services.

February Crypto Tracing Challenge

The analysis begins with two Ethereum transactions withdrawn from Tornado Cash:

0xddbedd32fbfc469328986d6c2d2aea76d6506a285acf027928a5a1e0020fc6ba
0xfedade8c27e3f0c13464254b174d105a5fd1edd1a6e8e05b5b85cbf493a51385

From these starting points, the objective is to identify the full laundering pathway.

Key Investigative Questions

What is the total volume (in ETH) withdrawn from Tornado Cash across the entire laundering flow?
How many deposit addresses are utilized to move funds through automated, non-custodial instant exchanges?

This challenge is designed to reflect real-world investigative scenarios, requiring a combination of blockchain analytics, pattern recognition, and financial reasoning.

For professionals working in financial crime investigations, litigation, asset recovery, or forensic accounting, this exercise offers a practical opportunity to sharpen tracing techniques in a controlled environment.

Interested in participating in future challenges?

You can join via The Bureau (accessible through our Linktree), complete verification, and assign yourself the challenge role.

If you require assistance, support is available via ticket.

🔍 MARCH CRYPTO TRACING CHALLENGE – FINAL CALL

The deadline is approaching quickly:

📝 DETAILS
If you’re looking to sharpen your crypto tracing skills in a practical, hands-on way, this is your last opportunity to take part in this month’s challenge.

This isn’t just about getting the “right answer”.
It’s about:
- Building a defensible tracing methodology
- Practising evidence-based analysis
- Developing confidence in manual tracing (not just tool reliance)

🎥 LIVE SOLUTION SESSION
I’ll be hosting a live teaching session where we walk through the full solution:
📅 Friday, 3 April 2026
🕙 10pm UK | 5pm EST

If you’re serious about improving your crypto investigation skills, this is exactly the kind of practice that makes the difference

See you in the challenge.

We’re rethinking our entire model - and I’d really value your input.

For a long time, people have come to us for help with serious, often difficult situations. And like many services in this space, we’ve charged for that work.

But the more we’ve done it, the more something hasn’t sat right:

The people who need help the most are often the ones least able to afford it.

So we’re exploring a different approach.

👉 What if investigations were free for victims
👉 And instead funded by the community - through courses, memberships, and shared knowledge?

The idea is simple:
Those who can contribute, make it possible for those who can’t.

But this only works if it’s built with the community - not just for it.

So before we move forward, I want to open this up:

• Would you support a model like this?
• What would make a membership or course genuinely valuable to you?
• What would you want to see in return for supporting real investigations?

And there’s one more thing.

If we do this properly, it feels like more than just a pricing change - it feels like a new chapter.

So I’m considering renaming the business to reflect that shift.

For those who choose to contribute early (whether through feedback, ideas, or early support), I’d love to open up the opportunity for you to help shape that - potentially even naming it.

This isn’t finalised. It’s something I’ve been thinking about for 5 years, and want to get right!

Appreciate any thoughts, ideas, or even challenges to this. 👇

There is a drainer campaign active - Some of the accounts are multiple years old. Please share/comment on the X post: https://x.com/rugpullfinder/status/2050125995835838906?s=20

It's seems to be a series of seed phrase compromises.

You can see here the connection between all victims form. One victim 'JasonBTC888' (shown in yellow) had up to 16 wallets drained!
