HNDL
A quantum threat attack pattern in which an adversary first intercepts and stores encrypted traffic and later decrypts it once quantum computers mature. For data with long confidentiality periods, the exposure window is already open.
Timeline (last 90 days)
An HNDL attack means an attacker captures encrypted traffic today and stores it, then decrypts it once capable hardware appears, so for data with a long confidentiality period the risk window is effectively already open.
Enabling hybrid key exchange on externally facing TLS is the highest-value early move, directly closing the HNDL window for traffic in transit.
