In this paper, we present SnailLoad, a new side-channel attack where the victim loads an asset, e.g., a file or an image, from an attacker-controlled server, exploiting the victim’s network latency as a side channel tied to activities on the victim system, e.g., watching videos or websites. SnailLoad requires no JavaScript, no form of code execution on the victim system, and no user interaction but only a constant exchange of network packets, e.g., a network connection in the background.
