A Nigerian in the United States on a student visa was sentenced to three years and 10 months in prison on Wednesday in a sophisticated fraud scheme that cost banks and other businesses millions of dollars.
Amechi Colvis Amuegbunam, 30 pleaded guilty in March to one count of conspiracy to commit wire fraud. He has been in custody since his arrest in Baltimore in August 2015.
The scheme Amuegbunam was part of had at least 10 victims and resulted in losses of about $3.7 million, according to a news release from the U.S. attorney’s office in Dallas. Amuegbunam has also been ordered to pay $615,555 in restitution.
From November 2013 through August 2015, Amuegbunam and others sent fraudulent emails to companies in North Texas and elsewhere including Luminant, Wells Fargo and J.P. Morgan Chase. The emails were designed to look like a forwarded message, supposedly from a top executive at the company, sent to an employee in the firm’s accounting department who had authority to make financial transfers, the news release said.
The investigation began when two businesses reported to the Dallas FBI office that they had received targeted spear phishing emails.
Although the emails appeared to be coming from a company executive, the messages were actually coming from a fake email account. The fraudulent domain name would contain one small difference from the company’s true email address, such as transposed letters. The investigation traced the creation of some of the documents to Amuegbunam.
