Patient names and colonoscopy results from US hospitals posted by hackers to the dark web Cybercriminals usually ask for ransom rather than leaking data Share this story Illustration by Ana Kova Patients of two US hospital chains had their names, birthdays, and colonoscopy results posted on the dark web after a hack, reported NBC News . The tens of thousands of files released were from patients at Leon Medical Centers in Miami and Nocona General Hospital in Texas. The patient records posted in this hack also include letters to insurers. There does not appear to be ransomware locking up the systems at Nocona, and the organization did not open a ransomware demand, an attorney for the organization told NBC News.
