A Nigerian national was sentenced in the United States for helping hack tax preparation businesses and steal customers’ personal and tax data. Prosecutors said Chukwuemeka Victor Amachukwu took part in spearphishing attacks against U.S. tax firms from 2019 to 2021, helping steal data on at least 800 people and use it to file fraudulent Internal Revenue Service and state tax refunds and Small Business Administration disaster-loan applications, causing about $3.3 million in losses.
Why it matters: Tax-preparation businesses and their clients remain attractive targets because one compromised inbox or workstation can expose enough identity data to fuel large-scale tax and loan fraud. Firms handling tax records should tighten phishing defenses and account security, while affected individuals should watch for tax-return and identity-theft abuse.
