New York: A large-scale cyberattack targeting US medical technology giant Stryker has raised serious concerns among cybersecurity experts after hackers claiming links to Iran said they launched the digital assault.

Who claimed responsibility for the Stryker cyberattack?
A hacking group calling itself Handala claimed responsibility for the attack through a message posted on Telegram. The group said it carried out the cyber operation in retaliation linked to ongoing geopolitical tensions in the Middle East.
Cybersecurity experts say the attackers used wiper malware, a highly destructive form of malicious software designed to permanently erase data from targeted systems.
Unlike ransomware attacks that demand payment, wiper malware focuses on destroying files and shutting down systems, making recovery more difficult.
Which Stryker operations were targeted?
According to early reports, the hackers specifically targeted Stryker’s major manufacturing facility in Cork, Ireland, which plays a key role in the company’s global medical device production network.
The attack reportedly disrupted internal systems and temporarily halted some manufacturing processes at the facility.
What actions have authorities taken after the cyberattack?
Stryker has begun working with cybersecurity experts and government agencies to investigate the breach and restore affected systems. Authorities in Ireland are also monitoring the situation closely.
Security analysts warn that the incident highlights the increasing vulnerability of healthcare and medical technology companies to cyberattacks.
Disruptions in this sector could potentially affect global healthcare supply chains, delaying the delivery of essential medical equipment to hospitals and healthcare providers worldwide.
The Stryker cyberattack comes amid rising concerns about state-linked cyber warfare, with experts warning that politically motivated digital attacks are becoming more frequent and more damaging.
