Statement on Unauthorized Access to Instinet Systems

On June 4, 2018 (EST), Instinet Europe Limited experienced the impact of a spear-phishing incident that resulted in unauthorized access to the firm’s desktop network.

Instinet responded immediately to the discovery of the attack by launching an investigation, activating a leading cybersecurity firm to assess and remediate the incident, and notifying appropriate authorities, including law enforcement. Although the investigation is ongoing, there has been no impact to Instinet’s execution and clearing systems.

There is no indication that the unauthorized access continues. There is no evidence the attacker accessed Instinet’s execution and clearing systems. Regular business operations have not been disrupted and steps have been taken to further protect Instinet’s ongoing operations.

This week we learned that some client and employee information was accessed. This led to our decision to announce the incident today, even though the investigation is ongoing. Instinet will work closely with clients to assess the potential impact.

Instinet remains committed to systems security, data privacy, and the protection of client and employee information.
