Last week, Staff at the Michigan-based firm claimed that the logo of an Iran-linked threat actor has begun popping up on login pages, while Stryker has said it is experiencing outages.
“Stryker is experiencing a global network disruption to our Microsoft environment as a result of a cyber attack. We have no indication of ransomware or malware and believe the incident is contained,” the company said on LinkedIn.
“Our teams are working rapidly to understand the impact of the attack on our systems.
“Stryker has business continuity measures in place to continue to support our customers and partners. We are committed to transparency and will keep stakeholders informed as we know more.”
While the company has said it believes the incident has been contained, Bloomberg has reported that the system disruption it suffered as a result of the cyber attack impacted its ability to deliver some of its personalised inventory, leading to delays.
“The system disruption has temporarily impacted the ability to deliver personalized inventory,” a Stryker spokesperson said.
“As a result, some patient-specific cases have been rescheduled.”
According to the Bloomberg article, a surgery for five-year-old Emmie Forrest was delayed. Forrest was set to get a custom-made Stryker implant this week to replace a portion of her skull, which is full of soft spots and holes.
However, as the implant is stuck in Germany as a result of the cyber disruption, the surgery has been delayed to next week.
Similarly, Major US hospital system CommonSpirit Health said that “a small number of surgical cases have been rescheduled” as a result of the cyber attack impacting Stryker.
While the incident has been contained, Stryker is still investigating the full scope and financial impact of the incident.
The company has not attributed the attack to any specific threat actor, however, the Handala hacktivist group has claimed responsibility.
Handala claimed to have wiped a massive 12 petabytes of company data.
“Today, for the first time, we proudly release the documentation of a unique cyber operation, an operation that will etch the name Handala Hack into the minds of all players in the global cyber security arena,” the group said on its website.
“In a swift and calculated attack, we succeeded in penetrating the deepest layers of the network belonging to the medical technology giant, Stryker. No system was safe from our sharp and capable eyes. During this operation, over 200,000 critical systems of this company were targeted and 12 petabytes of data (equivalent to 12,000 terabytes) were permanently wiped. Such a scale of data destruction is unprecedented to this day.”
Handala boasted that it was able to cripple “vital infrastructure” at will and that it would continue to target “all those who walk the path of oppression and aggression”.
Stryker says its recovery is still in progress.
