Dublin resident Vamsikrishna Naganathanahalli has been sentenced to 18 months in federal prison for damaging computers belonging to his former employer, MedAmerica, Inc., part of the Vituity group of companies. The sentence was delivered by U.S. District Judge Yvonne Gonzalez Rogers.
Naganathanahalli, aged 49, pleaded guilty on August 15, 2024, to three counts related to intentionally causing damage without authorization to a protected computer. His actions occurred after being informed that his employment with Vituity would be terminated. According to his plea agreement, he worked as a Senior HCM Architect for the company from October 2018 until June 2022.
On May 28, 2022, the day following his termination notice, Naganathanahalli used privileged access to change another employee's password without permission. On September 6, 2022, after his employment had ended, he accessed a contractor's account and uploaded files containing "dummy" or "masked" data into the live production environment of Vituity's Oracle Human Capital Management (HCM) platform. This act resulted in overwriting real data for approximately 90 percent of Vituity employees and caused a financial loss of at least $400,930.
Judge Gonzalez Rogers ordered Naganathanahalli to pay restitution amounting to $400,930 along with a $300 special assessment fee and imposed a three-year supervised release period following his imprisonment. He is scheduled to begin serving his sentence on July 20, 2025.
The announcement was made by United States Attorney Ismail J. Ramsey and FBI Acting Special Agent in Charge Dan Costin. The case is being prosecuted by Assistant U.S. Attorneys Michelle J. Kane and Nikhil Bhagat with assistance from Kathy Tat following an FBI investigation.
