Study on pacemakers found more than 8,000 known vulnerabilities in code inside the cardiac devices

I knew there are problems in medical devices security, but I did not know it's so bad.

​Researcher Billy Rios and Dr Jonathan Butts from security company Whitescope said their study showed the "serious challenges" pacemaker manufacturers faced in trying to keep devices patched and free from bugs that attackers could exploit.
They found that few of the manufacturers encrypted or otherwise protected data on a device or when it was being transferred to monitoring systems.
Also, none was protected with the most basic login name and password systems or checked that devices they were connecting to were authentic.
