Introduction
Cryptocurrency’s rapid rise has unfortunately been accompanied by a wave of fraud and criminal schemes. From high-yield investment scams to anonymous hackers stealing millions, crypto fraud has cost victims billions. In 2022 alone, cryptocurrency investment fraud reported to the FBI totaled an astounding $2.57 billion, and hackers stole another $3.8 billion. This article explores five common types of crypto fraud schemes and how forensic investigators combat them using blockchain analysis and traditional detective work.
Ponzi Schemes and Fake Crypto Investments
The Scam: Fraudsters create fake investment opportunities such as trading platforms, lending programs, or “high-yield” funds promising spectacular returns. Early investors may see profits, but these are simply funds from newer participants. Eventually, the platform collapses or the operators disappear with the money. Notorious examples include BitConnect and OneCoin.
Investigator’s Tactics: Forensic accountants and law enforcement analyze blockchain and banking transactions to uncover Ponzi behavior. By tracing deposits and payouts, they expose how new investors funded returns for earlier ones. Blockchain analytics help cluster wallet addresses and identify scammers. Subpoenas to exchanges can reveal real identities behind wallets.
Exchange Hacks and Stolen Crypto Assets
The Scam: Hackers target cryptocurrency exchanges and DeFi protocols to steal large sums of crypto. 2022 saw a record $3.8 billion stolen, especially from cross-chain bridges. State-sponsored groups like North Korea’s Lazarus Group have also been implicated.
Investigator’s Tactics: Investigators use blockchain explorers and forensic tools to trace stolen funds. They monitor wallet addresses and detect laundering through mixers or coin swaps. Law enforcement collaborates internationally to freeze assets and identify suspects, even using honeypot tactics or inserting tracking data into transfers.
Phishing, Impersonation, and Fraudulent Giveaways
The Scam: These scams exploit human psychology. Victims are tricked into revealing credentials via fake emails, or manipulated by impersonators posing as trusted figures. Romance scams and fraudulent giveaways on social media also fall into this category.
Investigator’s Tactics: Investigators identify shared scam wallet addresses and trace fund movements. Blockchain analytics tools and legal requests to exchanges help uncover fraudsters. Undercover operations and metadata analysis are used to infiltrate scam networks.
Rug Pulls and DeFi Exit Scams
The Scam: Developers of new tokens or DeFi projects hype up offerings and then withdraw all liquidity or reserves, crashing token values. Investors are left with worthless assets as the perpetrators vanish.
Investigator’s Tactics: On-chain analysts trace fund flows from token sales. Off-chain, they identify the developers behind the project. Mistakes, such as using a known KYC address, can lead to unmasking. Law enforcement builds cases using transaction data and other evidence.
Money Laundering via Mixers and Darknets
The Scam: Criminals use cryptocurrency to launder illicit funds—ransomware payments, drug trafficking proceeds, or bribes—via mixers, privacy coins, and darknet markets.
Investigator’s Tactics: Tools like Chainalysis and Elliptic identify transaction patterns and cluster wallet addresses. Forensic analysts monitor mixer activity and correlate deposits and withdrawals. When laundered funds interact with fiat systems, subpoenas help identify those cashing out.
