Hacking Heart Attacks
Mar. 12th, 2008 09:34 amSo, Here
is an article talking about a hacking attack that can turn off a certain
type of heart-monitor/pacemaker. The heartmonitor in question is used to
regulate the heartbeat, speeding it up it it gets to slow and shocking it if
it gets to fast. It also incorporates a radio which is used for
reprogramming by medical techs, so that the programming can be maintained
without open surgery. Now, that right there is a big security concern; it's
a necessary function of such a device, sure, but it should be clear that
such an interface needs to be protected. Apparently, there's no
authentication or encryption on the communication, which says to me that
nothing at all was done to secure the device. The attack, researchers
found, could be used to turn off the monitor or to deliver unnecessary
shocks to the heart, podssibly causing a heart-attack ("potentially fatal
arrythmia," they call it).
Now, the researchers didn't share their methodology, so a malicious attacker
would have to find it out on their own. And the manufacturer said that
newer modles will incorporate encryption and authentication. And they say
the chance of an attack is low, and requires expensive ($30,000+) equipment
and physical proximity (within whatever radio range they use). In today's
world, though, I can't help but fear that it's only a stone's throw away
from yet another sort of terror attack by a suitably-funded and motivated
adversary. It doesn't have the ahck and shaw value of crashing planes into
buildings or suicide bombings, so maybe it will be disfavored as not
striking enough, but it still makre me (as a security professional)
uncomfortable that such a sensitive piece of equipment was made without any
concern for security.
