Payroll/HR Giant PrismHR Hit by Ransomware?
Summary: PrismHR, which provides payroll, benefits and HR technology to hundreds of professional employer organizations serving more than two million employees and processing over $80 billion in payroll annually, detected suspicious network activity on Sunday, Feb. 28 and disabled platform access for all users. The company told PEO partners the disruption affected 200 PEO clients and said it would run this payroll period on estimates from the last one, with reconciliation once the platform returns; a notice from one PEO said PrismHR was rebuilding its entire system from data backups in a new environment.
What's compelling: Two million employees' pay and $80 billion in annual payroll run through this single platform, and PrismHR said it is not aware of any sensitive data being breached while acknowledging its investigation is ongoing - a claim its PEO clients and their customers can only hope holds.
