A citizen of Nigeria received an eight-year prison term after admitting participation in spearphishing campaigns aimed at American tax firms beginning in 2019.

The 40-year-old Chukwuemeka Victor Amachukwu, who also used the names Chukwuemeka Victor Eletuo and So Kwan Leung, admitted guilt to charges of conspiring to conduct computer breaches and wire fraud following his transfer from France to the United States during August 2025.

US Attorney Jamie McDonald stated in a Monday announcement that Amachukwu thought he could act freely from abroad while selecting targets, yet he has now faced consequences and will serve a substantial penalty for his offenses.

McDonald added that Amachukwu joined advanced operations to breach American companies, obtain and misuse stolen personal details from victims, and carry out fraud, causing notable damage to individuals and the public, which warrants a fitting punishment.

Court records show that Amachukwu and his partners took over three million dollars by submitting false tax and loan requests to the Internal Revenue Service and state agencies with stolen victim information.

Working alongside co-defendant Kingsley Uchelue Utulu and additional Nigerian associates, Amachukwu directed spearphishing efforts at tax preparation companies in New York, Texas, and further states from 2019 through 2021, securing illicit entry to systems and taking tax data plus personally identifiable information from no fewer than 800 clients.

Overall he secured roughly 2.5 million dollars in improper tax refunds after seeking 8.4 million dollars and an extra 819000 dollars via false loan filings under the Small Business Administration Economic Injury Disaster Loan program.

Amachukwu also took part in a sham investment operation that promised US targets stakes in nonexistent standby letters of credit, resulting in losses exceeding seven million dollars for several victims.

Beyond the prison sentence the court imposed one year of supervised release and required payment of 3.6 million dollars in restitution along with forfeiture of nearly 11 million dollars.
