Nytro Posted June 2, 2019 Report Share Posted June 2, 2019 KeySteal KeySteal is a macOS <= 10.13.3 Keychain exploit that allows you to access passwords inside the Keychain without a user prompt. KeySteal consists of two parts: KeySteal Daemon: This is a daemon that exploits securityd to get a session that is allowed to access the Keychain without a password prompt. KeySteal Client: This is a library that can be injected into Apps. It will automatically apply a patch that forces the Security Framework to use the session of our keysteal daemon. Building and Running Open the KeySteal Xcode Project Build the keystealDaemon and keystealClient Open the directory which contains the built daemon and client (right cick on keystealDaemon -> Open in Finder) Run dump-keychain.sh TODO Add a link to my talk about this vulnerability at Objective by the Sea License For most files, see LICENSE.txt.
