Medtronic’s management explained that such measures were taken in order to enhance the
cybersecurity of the IoT medical devices.
MAN IN THE MIDDLE ATTACK
Man in the middle is known as one of the most popular cyberattacks. It is used to intercept
private and sensitive data between two parties while they remain unaware. What happens is that
a cybercriminal disguises itself as a server and deceives a client into establishing a connection.
The client then initiates the connection and sends a request to the real server. The hacker is then
able to access this response and then passes it over to the client. In this way, all the communica-
tion between the client and the server are noted.
While using a man in the middle attack, it is important for the hacker to make sure that the
victim is routed to their server rather than connecting to the actual server. Once they are able to
establish communications, cybercriminals can read and save information all the HTTP/HTTPS
communications and transactions.

Meanwhile, the aected user has no idea since everything will be working as per routine
on their side. Moreover, the man in the middle attack can not only intercept information but
it can also change or modify the messages between two users. For example, user A sends $100
to user B through an online payment. If a user is able to successfully use the man in the middle
attack, then they can reduce the money to $50 and use the remaining money for themselves.
Therefore, their ability to change sensitive real-time data makes them a quite a dangerous
hacking strategy.
Since IoT products are riddled with security issues and have improper configurations, they
face a major challenge against the man in the middle attacks.
