White hats can earn as much as $40,000 for a single account-takeover bug. Facebook wants to encourage white hat hackers to poke at the platform in every way imaginable to find any undiscovered flaws before bad actors do so. The social network has been plagued by leaks and attacks over the years. Facebook hopes to encourage an even larger number of high quality submissions from existing and new white hat researchers to help secure over 2 billion users. The program extends to other services owned by the web giant, including Instagram, WhatsApp and Oculus.”]
