> Imagine one year where I dedicate two days a week learning, understanding and trying. Do I would have any chance at all to find something worth the $1M? Yes...but probably not the way you're thinking. Most issues are discovered these days through fuzzing first. So there is always a chance your fuzzer will find an issue worth $1M, its much less likely that you'll realize its worth or be able to demonstrate and begin to weaponize the exploit to prove its worth. Lets rephrase the question a little bit though: Instead of "Do I would have any chance at all to find something worth the $1M?" lets ask "Would I have any chance of learning this level of exploit development" Two days a week, lets just round to 50 weeks a year, give you a bit of a break during the year and say 100 days of effort. So, in a 100 days would you have any chance of reaching the level of being able to atleast write an iOS exploit, ignoring the discovery aspect? Unfortunately, the answer is still no. But, you would make some serious progress! A modern iOS zero-click exploit isn't just one issue, in a worst-case (okay there are worse than this, but this is a poor case) scenario you might need the following issues - Memory Leak + Entry Point service exploit - Sandbox Escape to low priv user - Privilege escalation to higher priv user - Kernel memory leak + Kernel exploit to finally get root privs This even for someone with experience, going from fuzz result to exploit can take months. So in a 100 days of spread out effort, you won't be doing that, but you might be able to begin approach that first stage, a memory leak and an exploit in a user-land service. I do only say might because 100 days is a really short time when you think about how technical your knowledge of this stuff needs to be, but I'd like to think that with some real determination, in 100 days at least foundations of modern software exploits should be approachable. As for would it make sense for you to even try, the best time to start was 20 years ago, its been getting increasingly more difficult. The longer you wait the higher the barrier to entry gets.
