Mac hacking competition winner mocks Apple security

Gaining root access to a Mac is "easy pickings", according to an individual who won an OS X hacking challenge last month by gaining root control of a machine using an unpublished security vulnerability.


On 22 February, the Sweden-based Mac enthusiast set up his Mac Mini as a server and invited hackers to break through the computer's security and gain root control, which would allow the attacker to take charge of the computer and delete files and folders or install applications.


Participants were given local client access to the target computer and invited to try their luck.


Within hours of going live, the "rm-my-mac" competition was over. The challenger posted this message on his Web site: "This sucks. Six hours later, this poor little Mac was owned, and this page got defaced."


The hacker who won the challenge, who asked ZDNet UK sister site ZDNet Australia to identify him only as Gwerdna, said he gained root control of the Mac in less than 30 minutes.


"It probably took about 20 or 30 minutes to get root on the box. Initially, I tried looking around the box for certain misconfigurations and other obvious things, but then I decided to use some unpublished exploits of which there are a lot for Mac OS X," Gwerdna told ZDNet Australia.


According to Gwerdna, the hacked Mac could have been better protected, but it would not have stopped him because he exploited a vulnerability that has not yet been made public or patched by Apple.


"The rm-my-mac challenge was set up similar to how you would have a Mac acting as a server with various remote services running and local access to users... There are various Mac OS X-hardening guides out there that could have been used to harden the machine, however, it wouldn't have stopped the vulnerability I used to gain access. There are only limited things you can do with unknown and unpublished vulnerabilities. One is to use additional hardening patches good examples for Linux are the PaX patch and the Grsecurity patches. They provide numerous hardening options on the system and implement nonexecutable memory, which prevent memory-based corruption exploits," Gwerdna said.


Gwerdna concluded that OS X contains "easy pickings" when it comes to vulnerabilities that could allow hackers to break into Apple's operating system.


"Mac OS X is easy pickings for bug finders. That said, it doesn't have the market share to really interest most serious bug finders," Gwerdna added.


OS X has come under fire in recent weeks with the appearance of two pieces of malware and a number of serious security flaws, which have since been patched by the Mac maker.


In January, security researcher Neil Archibald, who has already been credited with finding numerous vulnerabilities in OS X, told ZDNet Australia that he knows of numerous security vulnerabilities in Apple's operating system that could be exploited by attackers.


"The only thing which has kept Mac OS X relatively safe up until now is the fact that the market share is significantly lower than that of Microsoft Windows or the more common Unix platforms... If this situation was to change, in my opinion, things could be a lot worse on Mac OS X than they currently are on other operating systems," Archibald said at the time.


An Apple Australia representative said on Monday that the company was unable to comment at this stage. Representatives at Apple's Cupertino, California, headquarters could not be reached for comment.
