Terrapin attack: Overview, Related Topics & Entities

The Terrapin attack is a cryptographic attack on the commonly used SSH protocol that is used for secure command-and-control throughout the Internet. The Terrapin attack can reduce the security of SSH by using a downgrade attack via man-in-the-middle interception. The attack works by prefix truncation; the injection and deletion of messages during feature…
