Usenix Security 23 Isolated And Exhausted Attacking Operating Systems Via Site Isolation In

Usenix Security 23 Program At A Glance Usenix Site isolation is a security architecture for browsers to protect against side channel and renderer exploits by separating content from different sites at the operating system (os) process level. For (1) we show how to create a fork bomb, highlighting conceptual gaps in the site isolation architecture. for (2) we show how to block all udp sockets in an os, using a variety of advanced browser features.

We describe a way to mitigate the site isolation fork bomb in chromium based browsers without measurable performance penalty and include both the patch and our performance measurement results in this set of artifacts.

We show how to use site isolation and the attacks on first and second level resources to imple ment demons, a cache poisoning attack against the os dns resolver cache, in the web attacker model. Dns poisoning by exhaustive misappropriation of network sockets (demons), a dns cache poison ing attack uses site isolation to poison the dns cache of the windows operating system, in the web attacker model. In 2023, researchers at ruhr university bochum showed that they were able to leverage the process architecture required by site isolation to exhaust system resources and also perform advanced attacks like dns poisoning.
