The Annual Pwn2Own Hacking Competition 2015 held in Vancouver is over and participants from all over the world nabbed $557,500 in bug bounties for 21 critical bugs in top four web browsers as well as Windows OS, Adobe Reader and Adobe Flash. The star of the show was South Korean security researcher Jung Hoon Lee, nicknamed “lokihardt,” who worked alone and nabbed the single highest payout of the competition in the Pwn2Own history, an amazing bounty of $110,000 in just two minutes.
