Boston Children’s Hospital named in North Korean hacking operation

Security researcher Vangelis Stykas claims a large-scale North Korean hacking operation compromised systems across about 1,640 companies in 57 countries (with 700–800 described as seriously damaged), and publicly named organizations including Boston Children’s Hospital; the hospital disputes being breached, saying the issue traced to a former contractor’s personal device. The report relays the allegation and the dispute but offers no technical indicators or detailed forensic evidence.
