Forensic Accounting Methods

Cryptocurrency and crime are increasingly becoming inseparable — and yet, most law enforcement systems around the world are still catching up. Virtual Digital Assets (VDAs) like cryptocurrencies and NFTs pose serious challenges to investigators: pseudonymity, volatility, decentralisation, and complex technological architecture. To meet these challenges head-on, the Centre for Cybercrime Investigation Training & Research (CCITR), CID Karnataka has released a comprehensive manual titled “Investigation of Virtual Digital Assets: A Guide on Cryptocurrency Search, Seizure and Tracing.” This guide lays out the Standard Operating Procedures (SOPs) for safe, lawful, and effective handling of VDAs. It includes step-by-step protocols for setting up controlled wallets, seizing crypto assets, and tracing transactions — all based on real-world case scenarios and investigative needs. In a world where one wrong click can erase millions in assets or taint vital evidence, having a clear, tested SOP isn’t optional — it’s essential.

🎰 For years, we thought it was just illegal gambling. This past January, I was brought in to run the digital forensics on two raids — and uncovered $1.6M in crypto, a global scam networks, and a ring of corruption. Before Palau had a national digital forensics capability, raids like these were treated as straightforward: seize devices, arrest operators, and charge them with running online lotteries. That’s exactly how the January 2020 operation in Koror & Airai (142 arrests) and the January 2022 Cliffside View Hotel raid (62 arrests) were reported — “illegal online gaming” and nothing more. After I was brought in to conduct the digital forensics for the January 2025 raids at Cocoro Hotel, Beluu Seaview Resort, K2 Global, and Lagoon Apartments, the true nature of the crimes became very evident. I worked alongside the National Security Coordinator’s Office, Bureau of Public Safety, and the Financial Intelligence Unit and with support from Joint Interagency Task Force West, the United States Secret Service, the United States Department of Justice, and the International Criminal Police Organization (INTERPOL) — I applied cryptocurrency transaction tracing, hard-drive and file decryption, and structured digital evidence collection. What we uncovered was far more serious: • At least $1.6 million in inbound cryptocurrency tied to victim scams across borders • Complex money laundering networks • Work-permit fraud and corruption linked to local facilitators Without digital forensics capability, organized crime hides in plain sight. With it, we expose the truth, hold the right people accountable, and prevent communities from becoming a safe haven for transnational crime. That’s the difference the right capability — and the right team — can make.

Most people think that once crypto is sent, it’s gone forever. Even many investigators believe that. But here’s the truth: “Irreversible” does not mean “unrecoverable.” The #blockchain records everything. Every transfer, every hop, every attempt to hide. That level of transparency gives investigators a way forward. With the right approach, we can: ✅ Trace where funds move ✅ Follow activity across wallets ✅ Identify when stolen crypto lands on KYC exchanges ✅ Request freezes or subpoenas And yes, there have been real cases where stolen crypto was seized and returned, even years later. I know this because I've done it. So why the misconception? Because we often compare crypto to traditional banking. In traditional finance, you call your bank and hope they reverse the transaction. Crypto doesn’t work through reversals. It works through forensic visibility. Crypto removes the bank, not the evidence. The trail stays on-chain, available to those who know how to read it. Tools like Chainalysis and TRM Labs turn that data into actionable leads. Paired with law enforcement, recovery becomes possible. Here’s the mindset shift we need: 💥 If you work in fraud, compliance, cyber, or investigations, stop thinking “it’s gone.” Start thinking “let’s trace it.” Victims deserve that effort. Investigators deserve the full picture. #Crypto may not be reversible, but it’s far from hopeless. It simply requires a different playbook. Let’s start using it. 🦸🏿♂️ #Stopthescam Fraud Hero #Bitcoin #cryptocurrency #fraud #scam #fraudprevention

🕵🏽♀️ Why Crypto Crime Investigations Require Advanced Tools and Collaboration 👮🏽♂️ As someone who has worked crypto crime cases for years, I see this as a pivotal moment in how we confront Transnational Criminal Organized criminal networks. If the goal is to truly dismantle these TCOs, we must follow the money and seize it 💵 . That is where the real power lies. Cryptocurrency, despite being adopted by bad actors, has ironically become one of the most effective tools investigators have ever had for exposing financial flows. On-chain transparency, combined with the right analytics, provides law enforcement with a level of visibility into criminal finances that was previously unimaginable. For law enforcement, blockchain analysis platforms like Merkle Science's Tracker have become vital in tracing illicit funds across chains and wallets, helping agencies move from tip-off to action faster than ever. However, the right tools alone are not always enough. Investigators in this space also need: 👉🏽 Comprehensive and relevant training (ADBTraining™ Law Enforcement Training | We Are A Different Breed) 👉🏽 Collaboration 👉🏽 Clear legal framework (we might get it, finally) 👉🏽 Inter-agency cooperation (Verifi Wallet) 👉🏽 Effective public-private partnerships (Asset Reality) We still have a ways to go, but we are making progress.

Quick summary of our work into mapping the operational footprint of Coinomize, one of the longest-running Bitcoin mixers. We've been tracking changes in their infrastructure and obfuscation strategies over time, starting from cross-chain centralized swaps using Trezor wallet in the early days, through to swaps via eXch and Binance deposits, through to today where they rely heavily on THORChain and ShapeShift. This on-chain forensics work combined with some propietary OSINT has led Caudena to quite a unique view of Coinomize's operations.

I watched a $400/hour attorney spend Saturday night doing $15/hour work. And this is why her firm is struggling to grow. Your case manager is the one who keeps the train running. They handle client updates, deposition prep, calendar management, communication protocols, and so much more. The second they disappear into a mountain of PDFs, every other part of your file starts to slip. They don’t have time to be thinking about witness prep, client communication, or the hot docs that could win the case. Instead, they’re fixated on how many hours of sleep they are about to lose. This is the moment most litigation firms break. But you can help them. Separate the review from the strategy. A remote document review team handles the first pass. They work in batches through a secure portal, tagging notes directly to the documents so nothing has to be hunted for later. Your case manager stays on the strategy. They read the summaries. Connect the dots. Flag the gaps. Make sure the lead attorney walks into trial prep with a clean, organised file instead of a digital mess. And if this is set up correctly, it can change a lot in your firm. What would have taken four months gets done in six weeks. Each case manager regains 20 hours per week. And the hot doc folders become exceptionally well-vetted. The firms that scale high-volume discovery are the ones that stopped forcing their best people to do work a trained specialist could handle better and faster. We broke down exactly when to bring in remote document review support, and how to structure the collaboration so nothing falls through the cracks, in our latest article.

Crypto Sleuths Help Crack North Korea’s $1.5 Billion Blockchain Heist Introduction: The Largest Crypto Theft in History In late February 2025, the world witnessed the biggest cryptocurrency heist ever recorded—$1.5 billion in digital assets vanished within minutes from Bybit, a Dubai-based exchange. The audacious attack was later linked to North Korea’s notorious Lazarus Group. Behind the scenes, a group of digital crimefighters at TRM Labs worked with global law enforcement to trace the stolen funds, offering a glimpse into the high-stakes world of blockchain forensics. Key Details: How the Digital Trail Was Tracked • The Hack Exploiting vulnerabilities in Bybit’s systems, hackers siphoned $1.5 billion worth of crypto assets. The speed and scale of the heist shocked the crypto world and immediately raised suspicions of state-level involvement. • Immediate Response Bybit’s security team moved swiftly, involving the FBI and private sector specialists including TRM Labs—a San Francisco-based blockchain intelligence firm known for tracking illicit crypto activity worldwide. • TRM Labs’ Role From the first moments of the breach, TRM’s analysts helped trace stolen assets across decentralized networks. With roughly 300 experts, the company leverages blockchain analysis to investigate fraud, money laundering, and state-sponsored cyberattacks. • North Korea’s Involvement Confirmed The hack was ultimately attributed to the Lazarus Group, a well-known North Korean cybercriminal unit tied to previous high-profile attacks, including the infamous 2014 Sony Pictures breach. Why It Matters: A New Era of Cyber Warfare and Financial Crime • State-Sponsored Theft at Scale The Lazarus Group’s involvement underscores how nation-states are now exploiting cryptocurrency’s anonymity and global reach to fund rogue operations and bypass sanctions. • Blockchain’s Double-Edged Sword While crypto transactions are designed to be decentralized and secure, they’re also traceable. Companies like TRM Labs demonstrate how transparency in blockchain can be used to fight crime. • Public-Private Partnerships Work The success of the investigation reflects the critical role of collaboration between exchanges, tech firms, and law enforcement in countering digital financial threats. • Ongoing Threat Landscape Despite partial fund recovery efforts still underway, the scale of the heist signals that crypto platforms must continually adapt to increasingly sophisticated threats. Conclusion The Bybit heist is a turning point in cybercrime history—revealing both the vulnerabilities of global crypto infrastructure and the growing strength of digital crime fighters. As North Korea and other actors weaponize cyberspace for financial gain, companies like TRM Labs are proving that even in the decentralized world of blockchain, criminals can’t truly hide.

#Crypto Crime is Evolving. So Must Digital Investigations. DSCI's research report titled “Cryptocurrency Forensics for Law Enforcement” highlights an important reality: #cryptocurrency investigations are no longer just about blockchain tracing — they are about digital forensics across the entire technology stack. As digital assets continue to grow, cybercriminals are increasingly using crypto not as the starting point of crime, but as the final layer to obscure illicit proceeds. This shift is fundamentally changing how investigations must be conducted. Here are some key takeaways. 1️⃣ Crypto investigations now require hybrid forensic capabilities Traditional financial investigations are insufficient. Effective cryptocurrency investigations require the convergence of three disciplines: • Blockchain transaction tracing • Endpoint digital forensics (memory and disk artifacts) • Network and anonymization analysis Investigators must correlate on-chain data with evidence from suspect devices to establish attribution and admissibility in court. 2️⃣ Non-custodial wallets are reshaping the investigative challenge Criminals increasingly rely on non-custodial wallets and privacy tools because they control the private keys directly. This means investigators often need to recover evidence from: • wallet software artifacts • private key remnants in RAM • seed phrases stored locally • browser activity and Tor usage In many cases, the device becomes the crime scene. 3️⃣ Privacy coins and swap services complicate fund tracing The report’s case study demonstrates a typical laundering pattern used in ransomware cases: USDT → Monero → Ethereum The conversion through swap services and privacy coins breaks the traditional transaction trail, forcing investigators to rely on memory forensics, process analysis, and network artifacts to reconstruct events. 4️⃣ Volatile memory is becoming critical evidence One of the most striking findings is the importance of RAM acquisition during seizure. Even when suspects attempt to delete wallets or wipe files, memory analysis can reveal: • active wallet processes • cryptocurrency addresses • swap transactions • Tor browser activity • traces of secure deletion attempts Capturing volatile data quickly can preserve evidence that would otherwise disappear. 5️⃣ Open-source tools are democratizing crypto investigations The research emphasizes the power of free and open-source forensic tools such as: • Volatility (memory analysis) • FTK Imager (forensic acquisition) • Eric Zimmerman’s DFIR toolset This approach allows investigative units to build scalable crypto-forensics capability without heavy proprietary infrastructure. Crypto crime investigations are no longer purely financial investigations. They are cyber-physical investigations where blockchain analytics, operating system forensics, and network intelligence converge.
