New SnailLoad side-channel attack detailed


SecurityWeek reports that website and content inferencing could be remotely conducted by threat actors without direct network traffic access via the new SnailLoad side-channel attack technique.

Several latency measurements for websites and YouTube videos viewed by targets are being conducted by threat actors to establish digital fingerprints before luring targets to download files from a malicious server. Such content is slowly loaded by the server to enable continued tracking of connection latency, with threat actors potentially using a convolutional neural network for content inferencing.
