Two researchers examining the security of hospital networks have found many of them leak valuable information to the internet, leaving critical systems and equipment vulnerable to hacking. The data, which in some cases enumerates every computer and device on a hospital's internal network, would allow hackers to easily locate and map systems to conduct targeted attacks. In at least one case, a large health care organization was spilling info about 68,000 systems connected to its network. At this and every other facility that was leaking data, the problem was an internet-connected computer that was not configured securely.
