Stryker fully operational after crippling data-wiping cyberattack
Three weeks after a crippling cyberattack, Stryker Corporation, a leading medical technology company, says it’s fully operational across its global manufacturing network.
Last month, Stryker, an American Fortune 500 medtech company, was hacked via its internal Microsoft environment.
Allegedly, the attackers managed to gain access to a Microsoft Intune admin account, after which they executed a wipe command on tens of thousands of systems and servers.
The attack has been claimed by Handala, an Iranian-linked and pro-Palestinian hacktivist group. They claimed to have wiped 12 petabytes of data from the company’s servers.
“In this operation, over 200,000 systems, servers, and mobile devices have been wiped and 50 terabytes of critical data have been extracted,” Handala wrote on its victim blog site. In addition, the group said that offices in 79 countries were forced to shut down.
Three weeks after the data-wiping attack took place, all systems have been fully restored.
“As of this week, we are fully operational across our global manufacturing network. Production is moving rapidly toward peak capacity with discipline and stability, supported by restored commercial, ordering, and distribution systems. Overall product supply remains healthy, with strong availability across most product lines, as we continue to meet customer demand and support patient care,” the company said in an update regarding the incident.
“Our work continues around the clock in close partnership with third‑party cybersecurity experts, relevant government agencies, and industry partners as our investigation progresses, reflecting a shared commitment to protecting the healthcare ecosystem and supporting ongoing recovery efforts,” Stryker concluded.
