Investing.com -- Intuitive Surgical shares fell as much as 4% midday on Monday after the company disclosed that an unauthorized third party accessed information from certain internal IT business applications through a targeted phishing incident.

The company said it discovered the breach and quickly activated its incident response protocols, securing all affected applications. Intuitive stated that the information was obtained from an employee's compromised access into the company's internal business administrative network.

The accessed data includes some customer business and contact information, as well as Intuitive employee and corporate data. The company emphasized that the information was not obtained from its da Vinci or Ion systems.

Intuitive said its da Vinci, Ion and digital platforms were not impacted and continue to be safe and operational. The company noted that its network infrastructure is segmented, with separate networks for internal IT business applications, manufacturing operations, and its da Vinci and Ion platforms and digital products.

Hospital customer networks remain separate from Intuitive networks and are secured and managed by customers' IT teams, making them unaffected by the incident, according to the company.

Intuitive said there has been no impact on its operations or its ability to support customers. The company's robotic systems have their own security protocols and operate independently of its internal business network.

The company said it took immediate action to assess and contain the incident, begin an investigation, review security protocols, and remind employees of online security training and processes. Intuitive is communicating with its customers and notifying appropriate data privacy regulators.

The investigation is ongoing and the company said it will share updates as appropriate.
