Burkov admitted to access device fraud and conspiracy to commit access device fraud, identity theft, computer intrusion, wire fraud and money laundering in return for the dismissal of another three initial charges and now faces a maximum sentence of 15-year in prison.
The order signed on Thursday said "the sentencing hearing in this matter is CONTINUED to Friday, [June 26, 2020] at 9:00 a.m. [EST] as to Aleksei Yurievich Burkov."
The initial sentencing was scheduled to take place on May 8.
Burkov is suspected of running two websites for hackers - a floor for trading in stolen payment cards data and an "elite cybercriminals" forum. The prosecution said it believes that more than 150,000 cardholders and thousands of financial companies may qualify as victims in the trial.
