Attacking the Intel Secure Enclave

Interesting paper by Michael Schwarz, Samuel Weiser, Daniel Gruss. The upshot is that both Intel and AMD have assumed that trusted enclaves will run only trustworthy code. Of course, that's not true. And there are no security mechanisms that can deal with malicious enclaves, because the designers...

The vulnerability of the Open Enclave SDK, a software development tool, is related to an error in object processing in memory, which allows a hacker to disclose sensitive information that is protected by this security measure.

The vulnerability of the Open Enclave SDK software development tools is related to an object handling error in memory. Exploiting this vulnerability can allow a remote attacker to gain access to protected information...
