An Iranian hacker group, known as “Handala,” has claimed responsibility for a major cyberattack against U.S. medical technology company Stryker, allegedly compromising over 200,000 systems and extracting approximately 50 terabytes of data.
In a statement, the group described the operation as revenge for military strikes against Iran, citing what they called a violent attack on a school in Minab and ongoing cyberattacks on the Resistance Axis infrastructure.
The hackers claim that they have blocked Stryker offices in 79 countries and asserted that all data taken is now “in the hands of the free peoples of the world.” They also issued a warning to what they termed “Zionist leaders and their lobbies,” stating that this incident represents the beginning of a new chapter in cyber warfare.
Stryker, headquartered in Kalamazoo, Michigan, is a global leader in medical devices with roughly 56,000 employees and $25.12 billion in revenue in 2025. The company produces a wide range of equipment, including orthopedic implants, surgical instruments, hospital beds, and robotic surgical systems.
So far, the claims by the hacker group have not been independently verified.
