Finding serious vulnerabilities may give you a lot of money…
In this year “Pwn2Own” hacking contest, which is hosted by the Zero Day Initiative, Jack Dates from RET2 Systems executed a Safari to kernel zero-day exploit and earned himself $100,000. He used an integer overflow in Safari and an OOB write to get kernel-level code execution. The below demo in twitter shows more info.
Pwn2Own participants received more than $1.2 million in rewards for the discovered bugs.
