BOSTON — This is an official press release from the U.S. Department of Justice (USAO - Massachusetts), published as received.
BOSTON – A Nigerian national living in Mexico, who was extradited to the United States, was sentenced yesterday in federal court in Boston for his role in a scheme to break into Massachusetts tax preparation firms’ computer networks and to file fraudulent tax returns.
Matthew A. Akande, 37, was sentenced by U.S. District Court Judge Indira Talwani to eight years in prison, to be followed by three years of supervised release. Akande was also ordered to pay $1,393,230 in restitution. Akande was arrested in October 2024 at Heathrow Airport in the United Kingdom at the request of the United States and extradited to the United States on March 5, 2025. Akande was indicted by a federal grand jury in July 2022 with one count of conspiracy to obtain unauthorized access to protected computers in furtherance of fraud and to commit theft of government money and money laundering; one count of wire fraud; four counts of unauthorized access to protected computers in furtherance of fraud; 13 counts of theft of government money; and 14 counts of aggravated identity theft.
Between in or about June 2016 and June 2021, Akande worked with others to steal money from the United States government using taxpayers’ personally identifiable information (PII) to file fraudulent tax returns in the taxpayers’ names. The scheme also involved stealing taxpayers’ PII from Massachusetts tax preparation firms via phishing attacks and computer intrusions.
To carry out the scheme, Akande caused fraudulent phishing emails to be sent to five Massachusetts tax preparation firms. The emails purported to be from a prospective client seeking the tax preparation firms’ services but in truth were used to trick the firms into downloading remote access trojan malicious software (RAT malware), including malware known as Warzone RAT. Akande used the RAT malware to obtain the PII and prior year tax information of the tax preparation firms’ clients, which Akande then used to cause fraudulent tax returns to be filed seeking refunds. The tax returns directed that the fraudulent tax refunds be deposited in bank accounts opened by coconspirators in the United States. Once the refunds were issued, those coconspirators withdrew the stolen money in cash in the United States and then transferred a portion to third parties in Mexico, at Akande’s direction, while keeping a portion for themselves. In total, Akande and his coconspirators filed more than 1,000 fraudulent tax returns seeking over $8.1 million in fraudulent tax refunds over approximately five years. They successfully obtained over $1.3 million in fraudulent tax refunds.
Federal authorities encourage all businesses that suspect they have been the target and/or victim of a cyberattack to file a complaint with the Internet Crime Complaint Center at www.ic3.gov. Taxpayers and tax preparation firms that suspect they have been the target and/or victim of a phishing attack can also forward phishing email(s) to phishing@irs.gov.
United States Attorney Leah B. Foley; Ted E. Docks, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division; and Thomas Demeo, Acting Special Agent in Charge of the Internal Revenue Service’s Criminal Investigations in Boston made the announcement. The Justice Department’s Office of International Affairs coordinated with authorities in the United Kingdom to secure the extradition of Akande. Assistant U.S. Attorney David M. Holcomb of the Criminal Division prosecuted the case.
