/ Reply Attack: KSI defends MITM
attack by issuing a hash tree-based certificate generated with a pair value based on user's public key and ID of devices.
Moreover, to avoid the MITM
attack in directly sending public key to another device, the device owners need to assert the integrity of the public key.
It employed a Short Authentication String (SAS), which was a cryptographic hash of two DH values, for users to compare with each other's key and, hence, detect any Man-in-the-Middle (MITM
Hence, the MITM
(Man-in-the-Middle) attack is out of concern.

Rather than using TLS (HTTPS) to encrypt the data, Plantronics took an extra step to make sure that the message couldn't be easily unencrypted using TLS DPI or Man in the Middle (MITM
Vulnerabilities in its servers mean that it's possible to intercept that unencrypted traffic, re-route the encrypted data connections, and use a man-in-the-middle (MITM
) attack to break into the encryption.
A hacker was logged into his actual account sending and responding to e-mails in a fairly convincing and targeted Man in the Middle (MitM
