A major U.S. medical technology company called Stryker was hit by a serious cyberattack that disrupted its computer systems around the world. The company, based in Portage, Michigan, said attackers targeted its internal systems, making its computers and networks stop working.
The attack was claimed by a Iranian hackers group known as Handala. Hackers posted messages on social media saying they were responsible for the attack. They displayed their logo on Stryker’s login screens, and social media posts by company staff showed that company phones, laptops, and other Windows‑based devices were wiped stopped working.
Stryker makes important medical equipment used in hospitals around the world. The company builds surgical tools, artificial joints, hospital beds, and other products that help doctors provide care to patients. It has about 56,000 workers and operates in over 60 countries.
In a report to U.S. Securities and Exchange Commission (SEC), Stryker said the attack disrupted access to part of its computer systems and that the company is working to fix them. The company also said it has not found any ransomware or malware, which are common tools used by hackers to lock or steal data, and that the situation is under control.
Employees and contractors reported seeing the logo of the hackers group on login pages when they tried to access systems. Some company devices were stopped working, and there were reports of computer screens going blank and data being erased. Stryker did not say how long it will take to fix the issues or how much damage was done.
Industry analysts and cybersecurity experts say this type of attack shows how serious and harmful cyber threats are becoming, especially during times of rising global tensions. The hackers say their action was in retaliation for recent attacks on Iran and a missile strike at a school in Minab that killed many students, though the exact connection between Stryker and those events is unclear.
Even with the disruption, Stryker said that its important medical products and services, such as patient-care devices, were not directly affected by the attack. The company is continuing to support customers and partners while it works to fix the situation.
The attack also had an economic impact: Stryker’s stock price dropped after news of the cyber incident spread, showing that investors were worried about the company’s operations and future.
Cybersecurity officials and industry experts say this incident is a warning to other companies and industries to strengthen their network defence and data protection. Attacks like this can affect disrupt medical supply chains, internal communication, and production if systems are not properly protected.
Government authorities are watching this situation. The White House and U.S. cybersecurity organizations are monitoring the attack and are expected to work with private companies to respond to threats that affect national infrastructure.
This cyberattack on Stryker adds to a growing list of incidents where hackers have targeted major companies during times of rising political tension, and it highlights how digital security is now a major concern for global businesses that rely on connected systems.
