Key Takeaways
- Authorities allege a support impersonation scheme enabled unauthorized access to cryptocurrency wallets and digital accounts.
- Investigators estimate wallet losses exceeded $13 million, with additional potential victims still under review.
- Federal agencies previously warned that fake support contacts often use search ads and urgent security claims.
Support Impersonation Scheme Led to Crypto Wallet Losses
The Department of Justice (DOJ) announced on May 11 that an indictment targets an alleged cryptocurrency fraud and money laundering scheme exceeding $13 million. The case centers on unauthorized access to digital accounts and cryptocurrency wallets. Prosecutors charged Trenton Richard David Johnston, 19, of Canada, and Brandon Michael Tardibone, 28, of Miami.
Court documents say the alleged operation used impersonation tied to a popular search engine and cryptocurrency-related companies. After access was obtained, victims’ cryptocurrency holdings were allegedly transferred for the conspirators’ benefit. Investigators said more victims are still being identified, leaving the total scope of the alleged wallet losses open.
Prosecutors said:
“Johnston and other co-conspirators allegedly impersonated support representatives from a popular search engine and cryptocurrency-related companies to gain unauthorized access to victims’ digital accounts and cryptocurrency wallets.”
Charges include conspiracy to commit wire fraud and conspiracy to commit money laundering. Prosecutors also brought a harboring charge tied to lodging at a luxury Miami-area residence while Johnston was unlawfully present in the United States.
Laundering Claims Trace Crypto Proceeds to Luxury Spending
Laundering allegations focus on transactions prosecutors say concealed the nature and source of fraud proceeds. The indictment says more than $1 million funded luxury vehicle leases, high-end jewelry purchases, nightlife, and entertainment expenses. The DOJ detailed:
“Once access was obtained, the conspirators allegedly transferred victims’ cryptocurrency holdings for their own benefit. Investigators estimate that victims have suffered losses exceeding $13 million, with additional victims continuing to be identified.”
Separate FBI and Federal Trade Commission alerts issued before the Miami indictment described similar cryptocurrency support impersonation tactics. Those warnings outlined schemes where scammers posed as exchange or tech support staff, claimed accounts were compromised, and requested login credentials, two-factor authentication codes, seed phrases, or remote device access. Federal agencies also warned that fraudulent support numbers can appear through sponsored search advertisements and manipulated search results.
The methods described in those earlier federal alerts mirror key allegations in the Miami case, including support impersonation, unauthorized account access, cryptocurrency wallet transfers, and laundering tied to luxury spending. The indictment remains an allegation, and the defendants are presumed innocent unless proven guilty.
