The most notable flaw was exploited by the group Phoenhex & Qwerty: Hackers have managed to bypass browser defense mechanisms with a series of processes started with a JIT bug (just in time). In the end, the team was able to gain access on root (root), but even to the kernel (core) of the Mac in question ie complete control over all aspects of the machine.

The group has invoiced $ 45,000 for the discovery and took home the Mac used to invade; The prize was not higher because Apple was already aware of one of the bugs used in the venture and therefore should fix it soon.

The second successfully exploited bug in Safari was the work of the group Fluoroacetate: they managed to escape the sandbox browser with an integer overflow technique (integer overflow). The team billed $ 55,000 and could have made even more money had the technique not occupied almost all of the time given up for the operation; As this is a brute force attack (by trial and error), a long time passed while the machine tried to execute the correct code.
