The infiltration targeted the transfer processing systems for the transfer program, which pays part of the travel expenses of government employees.
It was unclear if any of the employees’ personal information was being used for criminal purposes.
The Department of Transportation informed Congress on Friday, in an email seen by Reuters, that its initial investigation into the data breach concluded that “the intrusion was limited to certain departmental systems used for administrative tasks, such as the processing of employee transfer payments”.
The ministry said in a statement to Reuters that the infiltration did not affect any of Salama’s transportation systems, and it did not specify who might be responsible for the intrusion.
She added that she was investigating the matter and preventing access to the transfer fee system until it was secure and operational again.
