Some healthcare employees are finding discrepancies in their paychecks, with Penn Highlands Healthcare among those providing regular updates on how the Kronos attack is affecting its payroll. In short, the time and attendance system outage will continue to impact payroll until the system is restored to full function. But Kronos has not provided an updated timeframe for when that might occur, nor can it advise clients on when the system will be again operational “since each of their thousands of clients must be reactivated individually,” Penn Highlands officials explained.
