Fujifilm shuts down computer systems following apparent ransomware intrusion

Posted on by

Fujifilm Corp. has shut down part of its computer network and “disconnected from external correspondence” in the face of a possible ransomware attack, the Japanese electronics giant said Wednesday. In a brief statement, Fujifilm said that it became aware of the security issue late Tuesday and that it has “taken measures to suspend all affected systems in coordination with our various global entities.” The company said it was still “working to determine the extent and the scale of the issue.” Fujifilm is just the latest multinational company to be hamstrung by ransomware. JBS, the world’s largest beef producer, had to temporarily shut down facilities in Colorado, Canada and Australia following a ransomware hack. Perhaps best known for its photography equipment, Fujifilm also makes a range of medical products such as CT Scan and Xray devices. The company reported more than $20 billion in revenue last year and has offices around […]

Can a CT scan be hacked? New research pushes doctors to patch their imaging devices

Posted on by

Health care providers and manufacturers of medical imaging devices (MIDs) need to be more vigilant when it comes to protecting their equipment, researchers from Ben-Gurion University say in a new research paper. The paper, published this month, details how researchers found that the devices are particularly vulnerable to threats that can ultimately result in harm to patients. “MIDs are increasingly connected to hospital networks, making them vulnerable to sophisticated cyber-attacks targeting the devices’ infrastructure and components, which can disrupt digital patient records, and potentially jeopardize patients’ health,” the paper’s abstract says. At particular risk are computed tomography (CT) machines because of their widespread use in acute care imaging, the researchers say. The researchers simulated cyberattacks on machines that conduct CT scans and their host computers and came away with several major risks. By gaining access to the configuration files on a CT machine’s host computer, hackers can change the way a […]
