Brooklyn Man Sentenced to Up to 12 Years for Stealing Nearly $16 Million From Coinbase

A Brooklyn man has been sentenced to up to 12 years in prison after stealing nearly $16 million from about 100 Coinbase users through a phishing and social engineering scheme, according to the Brooklyn District Attorney’s Office.

Ronald Spektor, 23, of Sheepshead Bay, was sentenced on September 23 to four to 12 years in prison after pleading guilty to all 31 counts in the case. The charges included first-degree money laundering, first-degree grand larceny and first-degree criminal possession of stolen property.

How the Coinbase Phishing Scheme Worked

Prosecutors said Spektor posed as a Coinbase representative and contacted users with warnings that their cryptocurrency accounts were at risk of being compromised by hackers.

The victims were then persuaded to transfer their assets to new cryptocurrency wallets that they believed were under their own control. According to investigators, the wallets were accessible to Spektor, allowing him to take the funds after they were transferred.

The Brooklyn District Attorney’s Office said the scheme resulted in approximately $15.944 million in losses involving about 100 U.S.-based Coinbase users. The investigation lasted about a year and involved more than 70 victims who were interviewed by authorities.

The stolen assets were subsequently moved through different cryptocurrency exchanges and swapping services. Investigators said portions of the funds were eventually used through gambling services, converted to cash or other cryptocurrencies, or spent on gift cards and digital assets.

Blockchain Analysis Helped Trace the Funds

The case also illustrates how blockchain transaction records can be used alongside traditional digital evidence in cryptocurrency investigations.

According to CoinMarketCap the Brooklyn District Attorney’s Office, investigators relied on transaction records, blockchain analysis, digital forensics and evidence obtained through multiple search warrants. Authorities also linked Spektor’s home IP address to several wallets from which cryptocurrency had been stolen.

Spektor pleaded guilty on September 2 to the entire 31-count indictment. Prosecutors had sought a sentence of seven to 21 years, but the court imposed a sentence of four to 12 years under the plea agreement.

In addition to the prison sentence, Spektor was ordered to forfeit cash, cryptocurrency and personal property valued at more than $500,000 and to make restitution of almost $16 million.

Authorities Warn Against “Safe Wallet” Requests

The Brooklyn District Attorney’s Office said Coinbase and most other companies will not call customers and instruct them to transfer cryptocurrency to a “safe wallet.” It also warned that caller IDs, sender names and lookalike domains can be spoofed.

The case concluded with Spektor’s sentencing on September 23, bringing the criminal proceedings against him to the sentencing stage while the restitution and forfeiture orders remain part of the case.
