- Masimo Corporation files new report with the SEC confirming attack
- It says it suffered a cyberattack that crippled operations
- No threat actors claimed responsibility yet
Masimo Corporation has confirmed suffering a cyberattack which crippled its operation and forced it to shut down parts of its infrastructure to address the problem.
In a new 8-K form filed with the US Securities and Exchange Commission (SEC), Masimo said that it spotted unauthorized activity on its on-premise network on April 27, 2025.
It responded by activating its incident response protocols and isolating impacted systems, and brought in third-party cybersecurity experts to analyze the attack, and notified law enforcement.

Ransomware or not?
The investigation is still ongoing, Masimo said, but confirmed that the attack crippled its operations: “As a result of the incident, certain of the company’s manufacturing facilities have been operating at less than normal levels, and the company’s ability to process, fulfill, and ship customer orders timely has been temporarily impacted,” the filing says.
“The company has been working diligently to bring the affected portions of its network back online, restore normal business operations and mitigate the impact of the incident.”
Attacks that force companies to shut down parts of their IT network usually end up being ransomware.
However, since Masimo’s cloud systems seem to be unaffected by the attack, this might not be the case. The investigation is still ongoing, so we’ll just have to wait and see. Also, no threat actors have claimed responsibility for the attack just yet.
Masimo is a US-based medical technology company that develops noninvasive monitoring solutions like pulse oximetry and brain function monitoring.
Healthcare organizations are often the targets of ransomware attacks, since they generate and hold huge amounts of highly sensitive information. Medical data can be resold on the dark web for profit, or used in targeted phishing attacks and identity theft.
