This feature was designed to keep even the most advanced users from accidentally installing malicious software on their computers.
The exploit was discovered by Patrick Wardle, director of research at security firm Synack.
Due to security concerns, the names of files have not been disclosed.
Therefore, lets call them Binary 1 and Binary 2.
Since, Binary 2 needs no digital certificate to run, it can install anything the attacker wants.
Gatekeeper hack exploit works on all Mac OS X versions including El Capitan and Yosemite.
Wardle stated that he was successfully able to test his exploit on the beta version of El Captain.
Im sure there are other Apple-signed apps out there that can also be abused to bypass Gatekeeper.
Meanwhile, Apple is aware of the flaw and is working on a patch to fix the underlying cause.
