      Bounties have little overlap w exploit development. Not in skill required, techniques developed, or bugs discovered.https://twitter.com/withzombies/status/839870870545850368 …

          To those dismissing this RAND report: Ignore it at your own peril. This is the best data ever released on real exploit development, period.

          Agreed! Modern exploit development chains several techniques into a working chain. Devs must be expert polyglots.

          where in the report do the authors make it clear that their definition of vulnerability does not include those on the OWASP top ten?
