In the case above, the company can prevent this from happening in the public Internet through the Use certificate pinning.
<h3>Should a person use certificate pinning?</h3>
Mobile applications are known to be one that often make use of certificate or also public key pinning so that they can be able to make sure that communications are secure.
Hence it is one that is often implemented if the developer of the application is said to be require to validate the remote host's identity or if operating in a harsh environment.
Hence, Certificate pinning hinders which certificates are considered valid for a any kind of website, and as such, In the case above, the company can prevent this from happening in the public Internet through the Use certificate pinning.

Yes , it’s true. In a known-plaintext attack (kpa), the cryptanalyst can only view a small portion of encrypted data, and he or she has no control over what that data might be.
The attacker also has access to one or more pairs of plaintext/ciphertext in a Known Plaintext Attack (KPA). Specifically, consider the scenario where key and plaintext were used to derive the ciphertext (either of which the attacker is trying to find). The attacker is also aware of what are the locations of the output from key encrypting. That is, the assailant is aware of a pair. They might be familiar with further pairings (obtained with the same key).
A straightforward illustration would be if the unencrypted messages had a set expiration date after which they would become publicly available. such as the location of a planned public event. The coordinates are encrypted and kept secret prior to the event. But when the incident occurs, the attacker has discovered the value of the coordinates /plaintext while the coordinates were decrypted (without knowing the key).
In general, a cipher is easier to break the more plaintext/ciphertext pairs that are known.
