This is a dev post classified by Jev as Security (a launch), kept by the Dev Radar because it carries real work, not commentary.

we've been asked several dozen times how we ended up at #1 on the @Hacker0x01 US leaderboard, and the answer is...Apex Black. we created an autonomous penetration testing system called APEX BLACK. it runs as a swarm of agents that can interact with applications like real users do. with hundreds of automated security capabilities, they can find any unexpected behavior and produce valid exploits. each time we point Apex at a target it finds a bug. we have not optimized to be #1, this is just a byproduct of our work. we will be talking more about our offensive security work so stay tuned!
