Handala Pro-Iran Hacktivist Group Targets Stryker With Cyber Attack Wipe

Stryker experienced a widespread cyber disruption when a suspected Iranian-linked hacking group, Handala, wiped its global technology systems. Employees found their Windows devices disabled and login pages displayed the group's logo. This incident led to a 3.82% decline in Stryker's stock price.

SYK, a major medical equipment maker, faced a significant cyber attack linked to a pro-Iran hacking group called Handala . The group claimed responsibility on TechCrunch, stating the attack was in retaliation for a U.S. strike on a Tehran school. The attack caused a widespread disruption affecting Stryker's global technology systems, with employees finding their Windows devices wiped and login pages displaying the Handala logo .

Employees were instructed to disconnect from corporate networks and not power on company devices as the company worked to contain the incident. Reports suggest pro-Iran hackers may have used wiper malware in the attack, a destructive tool designed to permanently erase data rather than hold it for ransom. Armadin CEO Kevin Mandia discussed the broader trend of Iranian-linked cyberattacks targeting U.S. tech firms and companies on Fox Business .

Stryker's stock fell 3.82% to $344.96 on the day of the attack , reflecting investor concern about operational disruption and potential data loss. The incident highlights growing geopolitical cyber risk for U.S. companies, particularly in the healthcare and defense-adjacent sectors, and may prompt increased cybersecurity spending industry-wide.
