Cybercrime Prosecution Involving Blockchain Tracing And Tracking
1. Introduction: Blockchain Tracing and Cybercrime
Blockchain technology underpins cryptocurrencies like Bitcoin, Ethereum, and others. While transactions are pseudonymous, every transaction is recorded on a public ledger, making blockchain transparent but immutable.
Blockchain tracing is the process of:
Identifying wallet addresses used in criminal activity.
Following transaction paths through multiple wallets.
Correlating blockchain activity with real-world identities using KYC (Know Your Customer) records, exchange data, and IP analysis.
Providing evidence for criminal prosecution of fraud, ransomware, darknet markets, or money laundering.
Tools used: Chainalysis, Elliptic, CipherTrace, and in-house forensic tools.
Common crimes prosecuted with blockchain tracing:
Ransomware payments
Darknet marketplaces
Cryptocurrency fraud and Ponzi schemes
Money laundering and terrorist financing
2. Case 1: United States v. Ross Ulbricht (2015) — Silk Road
Facts:
Ross Ulbricht created the Silk Road darknet marketplace for illegal drugs.
Payments were conducted in Bitcoin to obscure identities.
Blockchain Tracing Role:
Investigators analyzed Bitcoin transactions to Silk Road wallets.
Traced the flow of Bitcoin through multiple wallets to Ulbricht’s personal accounts.
Combined blockchain data with server logs, emails, and physical evidence.
Outcome:
Ulbricht sentenced to life imprisonment without parole for narcotics trafficking, money laundering, and computer hacking.
Significance:
First high-profile case showing blockchain tracing as crucial evidence in prosecuting darknet market administrators.
3. Case 2: United States v. Jeremy Spence (2020) — Cryptocurrency Fraud
Facts:
Jeremy Spence ran a fraudulent crypto investment scheme promising high returns.
He moved investor funds through multiple Bitcoin wallets to evade detection.
Blockchain Tracing Role:
Federal investigators traced the funds through over 200 Bitcoin wallets.
Linked cryptocurrency movements to Spence’s bank accounts and personal identity.
Outcome:
Convicted of wire fraud and money laundering; sentenced to 10 years in prison.
Significance:
Demonstrates complex fund layering in crypto fraud and the power of blockchain forensic analysis.
4. Case 3: United States v. Heather Morgan and Ilya Lichtenstein (2022) — Bitcoin Theft Recovery
Facts:
Hackers stole $119 million in Bitcoin from cryptocurrency exchange Bitfinex in 2016.
Funds were laundered via multiple wallets and cryptocurrency mixers.
Blockchain Tracing Role:
Investigators used blockchain analytics to follow the trail of stolen Bitcoin through mixers and wallets.
Identified cryptocurrency exchanges used to cash out funds, linking to Morgan and Lichtenstein.
Outcome:
Both defendants arrested and charged with conspiracy to commit money laundering and wire fraud.
The government recovered 94,000 BTC ($3.6 billion at 2022 prices).
Significance:
First large-scale recovery of stolen cryptocurrency using blockchain tracing.
Shows that even anonymized transactions can be linked to individuals.
5. Case 4: United States v. Ilya “Dutch” Lichtenstein (2022)
Part of the same Bitfinex hack investigation.
Blockchain tracing identified Lichtenstein as the primary operator moving stolen funds.
Cryptocurrency forensics allowed law enforcement to freeze wallets before cash-out, demonstrating real-time blockchain monitoring utility.
6. Case 5: United States v. Gelfman (2021) — Cryptocurrency Ponzi Scheme
Facts:
Defendant operated a crypto investment scheme promising high returns via Ethereum and Bitcoin investments.
Collected millions from investors but used funds for personal luxury expenses.
Blockchain Tracing Role:
Traced investors’ funds through multiple wallet hops and cross-chain transfers.
Connected blockchain transactions to bank accounts and asset purchases (cars, real estate).
Outcome:
Convicted of wire fraud and money laundering; sentenced to 12 years imprisonment.
Significance:
Highlights tracing of cross-chain transfers in crypto Ponzi schemes.
Demonstrates integration of blockchain analysis with traditional financial forensics.
7. Case 6: Colonial Pipeline Ransomware (2021)
Facts:
Colonial Pipeline paid 75 BTC (~$4.4 million) to DarkSide ransomware actors.
Blockchain Tracing Role:
FBI tracked ransom payment through multiple wallets.
Identified wallets linked to Russian-based DarkSide affiliates.
Facilitated partial recovery of 63.7 BTC (~$2.3 million).
Outcome:
Showed ransomware victims can recover crypto payments using blockchain tracing.
Federal law enforcement uses blockchain forensics as a preventive and reactive tool in ransomware attacks.
Significance:
Established procedures for rapid tracing of ransom payments.
8. Case 7: United States v. Sam Bankman-Fried (2023) — FTX Collapse
Facts:
FTX founder misappropriated customer funds, moving billions of dollars between accounts and crypto wallets.
Blockchain Tracing Role:
Forensic teams reconstructed fund flows using blockchain analytics.
Identified commingling of customer deposits with personal and corporate wallets.
Outcome:
Bankman-Fried arrested and charged with wire fraud, conspiracy, and money laundering.
Blockchain tracing was central to demonstrating misappropriation of funds.
Significance:
Illustrates the use of blockchain analytics in prosecuting high-level corporate crypto fraud.
