A British-Nigerian national has pleaded guilty in New York to involvement in a more than seven-year scheme to hack into banks’ and brokerages’ computer servers, causing more than $6 million of losses for customers. Idris Dayo Mustapha, 33, pleaded guilty to access device fraud, conspiracy to commit computer intrusion and securities fraud, and conspiracy to commit wire fraud at a hearing before U.S. District Judge. The native of Lagos faces up to 20 years in prison, he had been arrested in the United Kingdom in August 2021, and was extradited to the United States in August. Mustapha and his accomplices allegedly used phishing and other means to obtain user names and passwords and access online accounts from January 2011 to March 2018. Mustapha and his co-conspirators also developed romantic relationships online using the aliases “Melanie Saunders” and “Tracy Ben” in order to set up so-called “drop” accounts. After gaining their trust, they would convince unwitting targets to deposit checks and transfer money on their behalf.
