Automatic Data Processing Reports Hack Attack
In a press release, ADP said it was investigating the breach, which occurred at the company's recently-acquired benefits administration provider, Workscape.
While ADP confirmed that outside parties had accessed "non-payroll" data belonging to an unnamed client, the company is still investigating the magnitude of the intrusion and is working with law enforcement to locate the source of the attack.
The breach was discovered "during routine system monitoring," ADP said in the release.
"Protecting ADP clients and their data from malicious activity has been, and always will be, a top priority for ADP," the company also said, noting that the client has been informed of the attack.
