The FBI has seized multiple websites linked to hacktivist groups in the aftermath of a significant cyberattack that disrupted Stryker Corporation’s operations. The action targets platforms used to claim responsibility for and coordinate cyberattacks on healthcare and critical infrastructure targets, marking a strong law enforcement response to rising hacktivist threats against medical device manufacturers and hospitals.
Glimpse:
Following the recent cyberattack that affected Stryker’s systems and forced hospitals to implement manual workarounds, the FBI executed warrants to seize several hacktivist-affiliated websites and domains. The seized sites had been used to publicize the attack, share leaked data, and recruit participants for further operations. Authorities are investigating the groups behind the incident, with early indications pointing to ideologically motivated actors targeting the healthcare sector. Stryker has confirmed ongoing cooperation with law enforcement while focusing on full system restoration and enhanced security measures.
The Federal Bureau of Investigation (FBI) has carried out a series of seizures targeting websites and online platforms associated with hacktivist groups following the recent cyberattack on medical technology giant Stryker Corporation. The operation, executed in coordination with international partners, involved taking down multiple domains and servers that were used to claim responsibility for the attack, disseminate messages, and potentially coordinate further disruptive activities against healthcare and critical infrastructure targets.
The Stryker cyberattack, which occurred in late February 2026, caused widespread operational disruption, affecting manufacturing systems, customer portals, and certain connected medical devices. Hospitals relying on Stryker equipment were forced to activate contingency plans, postpone non-emergent procedures, and shift to manual workflows. While Stryker has since declared the incident contained and is working on full restoration, the attack highlighted the vulnerability of the healthcare supply chain to both ransomware-style operations and ideologically driven hacktivist campaigns.
The FBI’s seizure of the hacktivist websites is seen as a decisive step to disrupt the propaganda and recruitment channels used by these groups. Investigators are examining digital evidence linking the platforms to the Stryker incident and other recent attacks on healthcare entities. Officials have not yet publicly identified the specific groups responsible, but sources indicate the actors combined technical sophistication with public messaging aimed at drawing attention to perceived grievances related to healthcare access and corporate practices.
Stryker has been cooperating fully with law enforcement and has strengthened its cybersecurity posture in response to the incident. The company continues to support affected customers with on-site technical assistance and interim solutions while emphasizing that patient safety was never compromised. The broader healthcare industry has taken note of the event, with many hospitals and device manufacturers accelerating reviews of their own vendor risk management and incident response plans.
This law enforcement action underscores the growing seriousness with which U.S. authorities are treating cyberattacks on healthcare, especially those that could impact patient care or critical medical supply chains. Further arrests or additional seizures are expected as the investigation progresses.
“We will not tolerate attacks that threaten the healthcare system and the patients who depend on it. These seizures send a clear message that those who target critical infrastructure will be pursued and held accountable.”
