Masimo, a California-based manufacturer of patient monitoring and medical devices, experienced a cyberattack on its on-premises network discovered on April 27. The incident temporarily disrupted the company’s ability to fulfill customer orders, though it clarified that the attack would not materially impact its fiscal 2025 revenue (projected between $1.5B–$1.53B) or its capacity to meet seasonal demand. Critical systems—including order processing, distribution, and shipping—were restored to near-full operational capacity, with ongoing optimizations to address delayed orders. The company engaged third-party forensic experts and law enforcement for investigation and mitigation. While the attack caused operational disruptions, Masimo confirmed its cyber insurance policy would cover most remediation costs. No evidence of data exfiltration, ransomware demands, or compromise of sensitive customer/employee data was reported, limiting the incident’s financial and reputational fallout to temporary logistical delays.
