Terrapin Attack: Breaking SSH Channel Integrity By Sequence Number Manipulation

arXiv:2312.12422v2 Announce Type: replace
Abstract: The SSH protocol provides secure access to network services, particularly remote terminal login and file transfer within organizational networks and to over 15 million servers on the open internet. SSH uses an authenticated key exchange to establish a secure channel between a client and a server, which protects the confidentiality and integrity of messages sent in either direction.
