A former senior security engineer, Shakeeb Ahmed, has been arrested in New York for wire fraud and money laundering. The charges stem from an attack on a decentralized cryptocurrency exchange.
Ahmed exploited a vulnerability in one of the Crypto Exchange’s smart contracts in July 2022. By inserting fake pricing data, he fraudulently caused the smart contract to generate approximately $9 million in inflated fees, which he subsequently withdrew as cryptocurrency.
The fraudulent conduct not only defrauded the Crypto Exchange but also affected its users, whose cryptocurrency Ahmed obtained through deceptive means. The indictment further details Ahmed’s use of cryptocurrency “flash loans” to perpetrate additional fraud against the exchange.
Following the theft, Ahmed engaged in communications with the Crypto Exchange, offering to return all stolen funds, except for $1.5 million, on the condition that the exchange refrained from reporting the attack to law enforcement.
Ahmed’s laundering techniques included conducting token-swap transactions, bridging fraud proceeds from the Solana blockchain to the Ethereum blockchain, exchanging funds into the difficult-to-trace cryptocurrency Monero, and utilizing overseas cryptocurrency exchanges.
HSI Special Agent in Charge Chad Plantz emphasized the importance of combating financial crimes that threaten national and economic banking security. Plantz highlighted the need to protect consumer confidence in the financial system and dismantle complex fraud schemes, regardless of their technical nature or the locations from which they operate. IRS-CI Special Agent in Charge Tyler Hatcher also underscored the commitment of his agency, along with HSI and the Department of Justice, to track down and hold fraudsters accountable.
As the legal proceedings against Shakeeb Ahmed unfold, it serves as a reminder that law enforcement agencies are actively combating cryptocurrency-related crimes. Authorities remain vigilant in their pursuit of fraudsters, utilizing advanced cyber investigation techniques to track and apprehend individuals attempting to defraud the financial system.
