Bypassing Gatekeeper (again)

Yes, Patrick Wardle of Synack has done it again.

Apple’s fix for the exploit reported by Ars Technica back in September and enabling him to bypass Gatekeeper was to blacklist the files he reported to them privately. However, when Wardle found another trusted file that enabled him to use the same attack methodology.

Wardle, who will be making a related presentation at Schmoocon this weekend, delivered a presentation at Virus Bulletin in 2015 intended to ‘expose the inner workings of Gatekeeper and … delve into the concept of quarantined files.’

Hat tip to Randy Knobloch (@randyknobloch) for drawing my attention to the Ars Technica article.
