Cyber Reconnaissance of foreign leaders through implantable medical devices

In an earlier article I had talked of the frightening under preparation of medicine against cyber attacks I had listed some resources- here

Some more papers on this are here https://spqr.eecs.umich.edu/papers/b1kohFINAL2.pdf and here http://www.cis.temple.edu/~jiewu/research/publications/Publication_files/Defending%20Resource%20Depletion%20Attacks%20on.pdf and here http://gao.gov/assets/650/647767.pdf

Sadly there is a complete lack of updated research in public arena. I wonder if the cloud era needs a new eco system of Information Security. Where is John McAffee when you need him?

With Cyber Snooping or Cyber Reconnaissance (NSA) much in the news lately, I wonder if countries monitor the health of foreign leaders like Sonia Gandhi etc through medical devices- a good number of these surgeries are done in the United States for political leaders.
