TFTP (Trivial File Transfer Protocol) is a lightweight file transfer protocol commonly used in local networks.
Overview
TFTP (Trivial File Transfer Protocol) is a lightweight file transfer protocol commonly used in local networks. In cybersecurity, attackers may abuse TFTP due to its lack of authentication and encryption to move payloads, exfiltrate data, or establish covert channels, especially in OT/ICS environments. The referenced article discusses a Russian threat group targeting Western critical infrastructure, illustrating the ongoing risk to critical infrastructure where simple tools like TFTP could be leveraged, though it does not explicitly link TFTP to the activity.
