ADP Statement Regarding Petya Ransomware

July 05, 2017

From: Client Security Management Office ADP Global Security Organization

A global cyber-attack impacting businesses and critical services known as “Petya ransomware” has been widely reported in the news. This attack is carried out through phishing emails and locks down all files on infected computers until the user pays to release control of those files.

At this time, ADP has determined that none of its internal systems have been compromised by this attack, and no intrusion has occurred. Systems hosting ADP products have been patched to prevent the “Petya ransomware” threat.

ADP’s Global Security Organization continues to actively monitor this situation as it does with all reported malware activity. Clients are encouraged to visit ADP’s Trust Center at to learn more about how ADP protects security and privacy, and how clients can help protect themselves.

Protecting our clients and their data from malicious activity is a top priority for ADP.
