In the rapidly evolving world of Web3, where innovation moves at lightning speed, so too do cybercriminals. As decentralized finance (DeFi) reshapes global financial systems, it also opens new avenues for fraud, money laundering, and sophisticated scams. But behind the scenes, a new breed of digital detectives is fighting back — using advanced blockchain analysis to track illicit activity and protect users.
In this deep dive, we explore insights from a former U.S. military and Department of Defense intelligence analyst — now a blockchain intelligence specialist at TRM Labs, one of the world’s leading blockchain analytics firms. Speaking anonymously as "John," he brings over 15 years of national security experience into the world of crypto forensics, offering a rare glimpse into how intelligence tactics are being repurposed to secure the blockchain ecosystem.
The Mission Behind TRM Labs
TRM Labs is a U.S.-based blockchain intelligence company that provides anti-money laundering (AML) and fraud detection tools to law enforcement agencies, financial institutions, and virtual asset service providers (VASPs), including major crypto exchanges like XREX.

At its core, TRM builds a digital identity database that maps wallet addresses to real-world entities. This allows institutions to flag high-risk transactions, trace fund flows, and identify connections between seemingly unrelated wallets — especially those involved in scams, ransomware, or sanctioned activities.
“Think of us as building a fingerprint library for criminal behavior,” explains John. “We combine human intelligence with AI to recognize patterns — how funds move, how they’re mixed, and how bad actors try to hide.”
This fusion of traditional intelligence methods with cutting-edge technology has become essential in an era where cybercriminals operate across borders with near-anonymity.
From Battlefield Intelligence to Blockchain Forensics
John spent 15 years in high-stakes intelligence roles within the U.S. military and defense sector, including deployments in conflict zones like Iraq. Today, while the battlefield has shifted from physical terrain to digital ledgers, the mission remains the same: protect innocent people and stop malicious actors.
“What surprised me is how similar blockchain investigation is to national intelligence work,” John shares. “Back then, I worked on APT groups — Advanced Persistent Threats — often state-sponsored hackers running long-term cyber campaigns. Now, I see organized crime syndicates using similar persistence and sophistication in crypto scams.”
The key similarity? Persistence. Just as APT groups maintain long-term access to systems, scam operations — especially romance scams ("pig butchering") and investment frauds — run for months or even years, building trust before striking.
And just like in military intelligence, success comes not from one breakthrough, but from piecing together small clues over time.
How Blockchain Analysis Works: Pattern Recognition Meets AI
Modern blockchain forensics relies on two pillars: human-driven intelligence gathering and automated pattern detection.
Human Intelligence (HUMINT) in Crypto
Much of TRM’s early detection capability comes from collaboration with law enforcement and regional partners. Local knowledge — such as common scam scripts in Southeast Asia or emerging phishing tactics in Latin America — helps build context that machines alone can’t interpret.
For example, identifying a "cold wallet" used by a known scam group allows analysts to trace all incoming and outgoing transactions. Any wallet interacting with it becomes a potential red flag — even if it hasn’t been labeled yet.
“This is how we expand our network of detection,” says John. “One known bad actor leads to ten more.”
Graph Analytics & AI Detection
Once initial intelligence is gathered, technology takes over. Using graph theory, TRM analyzes transaction networks to spot behaviors typical of money laundering:
- Peeling chains: Gradually moving funds through many small transfers.
- Mixing services: Blending dirty funds with clean ones.
- Circular flows: Sending money in loops to obscure origin.
These patterns can be detected without knowing identities — purely based on behavioral data.
Wayne Huang, CEO of XREX, compares this to antivirus software evolution: “Just like malware authors test their code against 40 different antivirus engines before release, scammers now test their wallets against compliance tools. That’s why we need deeper, smarter defenses.”
Real-World Impact: Stopping Scams Before They Spread
Despite the complexity of crypto crime, progress is measurable.
According to TRM Labs’ data, illicit transaction volumes dropped from $49.5 billion in 2022 to $34.8 billion in 2023 — a decline of about one-third. Meanwhile, the proportion of illegal activity relative to total crypto volume fell from 0.7% to 0.6%, signaling improved detection and deterrence.
Notable successes include:
- Assisting U.S. Secret Service in seizing $5 million linked to pig-butchering scams.
- Supporting New Hampshire prosecutors in returning $3.5 million to victims.
“These aren’t just numbers,” emphasizes John. “Each dollar recovered represents someone who didn’t lose their life savings.”
But here's the catch: not all detected threats are immediately shared with clients.
The Delicate Balance: When to Share Intelligence
Crypto compliance firms face a critical dilemma: when should they release newly discovered threat indicators?
Releasing them too early risks alerting criminals mid-investigation — allowing them to change tactics or disappear. But withholding data means exchanges may unknowingly process illicit transactions.
John describes the solution as a “help me help you” model: close coordination with law enforcement to time disclosures perfectly — ideally right after arrests or asset freezes.
“We don’t dump everything at once,” he explains. “We sync with agencies so our clients get alerts exactly when it won’t compromise ongoing operations.”
This careful choreography ensures both public safety and investigative integrity.
The Future of Fraud: Smarter, More Organized Criminal Networks
While current efforts are working, criminals are adapting.
John warns of a shift toward professionalization and specialization within scam ecosystems — what he calls the “crime economy.” Just as legitimate industries divide labor, fraud networks now include:
- Recruiters who target victims via social media.
- Psychologists who manipulate emotions in romance scams.
- Tech teams managing fake trading platforms.
- Money mules handling withdrawals and conversions.
And with AI-powered voice and face spoofing becoming mainstream, deepfake scams are no longer sci-fi — they’re already happening.
“I’ve heard of cases where scammers used AI to mimic a daughter’s voice crying for help,” says John. “Without safeguards, anyone could fall for it.”
Protecting Yourself: Simple Steps That Work
You don’t need a security clearance to stay safe online. John offers practical advice every user can follow:
1. Use Dedicated Devices for Transactions
Never perform crypto transfers on devices used for browsing or messaging. Instead:
- Use a cheap, dedicated Chromebook or phone only for sending funds.
- Avoid copying wallet addresses from untrusted sources.
👉 Learn how secure wallets prevent address tampering automatically.
2. Practice Wallet Hygiene
- Keep large holdings in cold storage (offline wallets).
- Use separate wallets for daily transactions.
- Never store private keys on connected devices.
3. Set Up a Family Verification Code
Create a shared passphrase with loved ones — especially those who might send urgent money requests.
- Example: Combine languages (e.g., “WoAiNi88” = Chinese + numbers).
- If someone claims to be in distress but can’t provide the code, verify via another channel first.
4. Stay Skeptical of Urgency
Scammers create pressure: “Send money now or lose your investment!” Slow down. Verify. Double-check.
