A medical device hijack (also called medjack) is a type of cyber attack.The weakness they target are the medical devices of a hospital. This was covered extensively in the press in 2015 and in 2016.
A time/memory/data tradeoff attack is a type of cryptographic attack where an attacker tries to achieve a situation similar to the space–time tradeoff but with the additional parameter of data, representing the amount of data available to the attacker.
