Installing Fake Root Keys in a PC

摘要

If a malicious party can insert a self-issued CA public key into the list of root public keys stored in a PC, then this party could potentially do considerable harm to that PC. In this paper, we present a way to achieve such an attack for the Internet Explorer web browser root key store, which avoids attracting the user's attention. A realisation of this attack is also described. Finally, countermeasures that can be deployed to prevent such an attack are outlined.
