Bug Bounty Hunting on Steroids [DEF CON 26]

(Note: These slides were originally posted on our BountyMachine team account: https://speakerdeck.com/bountymachine/bug-bounty-hunting-on-steroids)

Not all hacking is fun. A lot of repetitive manual work is usually required to map the target infrastructure and decide which assets are worthy of giving attention to first. Surely there’s a better approach.

1. @anshuman_bh @_devalias @mhmdiaa Bug Bounty Hunting on Steroids
2. @anshuman_bh @_devalias @mhmdiaa Mohammed Diaa @mhmdiaa Developer, Bug Hunter Never send a human to do a machine’s job Glenn ‘devalias’ Grant @_devalias Hacker, Polyglot Developer, Bounty Hunter, #SecDevOpsInTheCloudCyber™ enthusiast... Penetration Tester and Offensive Capability Development at TSS The Team Anshuman Bhartiya @anshuman_bh Security Engineer, Bug Bounty Hunter Automate all the things!! All things as code!! 2
3. @anshuman_bh @_devalias @mhmdiaa Agenda • Problem? • Current Situation • Target: Ellingson Mineral Corporation • Introducing BountyMachine • Lessons Learned • Conclusion 3
4. @anshuman_bh @_devalias @mhmdiaa Problem? • Not all hacking is fun. A lot of manual repetitive work. • Building everything from scratch is a bad idea.. • How do we scale across thousands of targets? • Things change all the time, we need continuous monitoring 4
5. @anshuman_bh @_devalias @mhmdiaa Current Situation 5
6. @anshuman_bh @_devalias @mhmdiaa Redundancy Between Tools Not invented here / anti unix philosophy is prevalent
7. @anshuman_bh @_devalias @mhmdiaa An unmaintained tool is born 7 https://xkcd.com/927/ ToolA released: does a few things ToolB released: handles some missing bits, but fails in other areas Maintainers (often a single point of failure) move on to something new.. Back to square one!
8. @anshuman_bh @_devalias @mhmdiaa 8 You can’t build everything from scratch shouldn’t
9. @anshuman_bh @_devalias @mhmdiaa Lack of Reliable Tool Comparisons You don’t know the right tool for the job unless you try all of them.. and there are a lot...
10. @anshuman_bh @_devalias @mhmdiaa The situation is improving! The Bug Hunter’s Methodology by Jason Haddix (@jhaddix) https://github.com/jhaddix/tbhm Thanks, Jason! You’re awesome \m/ 10
11. @anshuman_bh @_devalias @mhmdiaa 11
12. @anshuman_bh @_devalias @mhmdiaa Poor Interoperability Many tools just don’t play nicely with each other
13. @anshuman_bh @_devalias @mhmdiaa • JSON-based recon tool data output standard • Increase interoperability between tools • Enable a unix-philosophy recon tooling digital utopia! Join the discussion: https://github.com/ReconJSON/ReconJSON ReconJSON 13
14. @anshuman_bh @_devalias @mhmdiaa Scaling & Reliability Learning from the dev side of the tech world
15. @anshuman_bh @_devalias @mhmdiaa Scaling & Reliability • Vertical scaling ◦ More server, more money, more problems • Horizontal scaling ◦ Flexible, fault tolerant, cheaper • Learn from the tech giants ◦ Great architectures and tools to leverage 15
16. @anshuman_bh @_devalias @mhmdiaa Practical Research Environment There are tons of assets that you can hack legally
17. @anshuman_bh @_devalias @mhmdiaa I just want to hack things... Wouldn’t it be nice to have: • An organized database with all the assets that are legal to hack ◦ Stick to the scope • A supporting platform that collects data about these assets ◦ Fast feedback loop • A way to easily explore the asset data ◦ Locate targets and #HackAllTheThings™ 17
18. @anshuman_bh @_devalias @mhmdiaa It’s all about identifying assets What you don’t know about, you can’t protect
19. @anshuman_bh @_devalias @mhmdiaa Unmaintained assets cause breaches 19 https://snyk.io/blog/owasp-top-10-breaches
20. @anshuman_bh @_devalias @mhmdiaa Unmaintained assets cause breaches A9-Using Components with Known Vulnerabilities 12/50 breaches 24% A5-Security Misconfiguration 10/50 breaches 20% 20
21. @anshuman_bh @_devalias @mhmdiaa Real-time inventory of target assets Ephemeral assets, they said. It will be fine, they said.
22. @anshuman_bh @_devalias @mhmdiaa Attack surface is always evolving Code changes Bugs/regressions New code Backups New assets Hosts Cloud services Subdomains 22
23. @anshuman_bh @_devalias @mhmdiaa Target 23

25. @anshuman_bh @_devalias @mhmdiaa What we know... 25
26. @anshuman_bh @_devalias @mhmdiaa 26 Let’s start the demo...

35. @anshuman_bh @_devalias @mhmdiaa Everything is managed by queues 35
36. @anshuman_bh @_devalias @mhmdiaa The output of a workflow can be passed to another 36
37. @anshuman_bh @_devalias @mhmdiaa New results are identified by a diff worker 37

45. @anshuman_bh @_devalias @mhmdiaa Dealing with conflicts 45 • Check your ego • Communicate openly, honestly and thoroughly! • Stay open to new suggestions • Delegate responsibilities • Be flexible • Code/data trumps assumptions
46. @anshuman_bh @_devalias @mhmdiaa Technology 46
47. @anshuman_bh @_devalias @mhmdiaa Technology 47 • Keep an open mind • Explore what is out there • Dig deep, understand how the underlying tech works • Sometimes what you want doesn’t quite exist yet.. and that’s ok • ‘Simple’ problems sometimes take a while to solve well
48. @anshuman_bh @_devalias @mhmdiaa MVP? JIT! 48
49. @anshuman_bh @_devalias @mhmdiaa MVP? JIT! 49 • Plan at the macro level • Handle intricate details Just In Time (JIT) • Backlog anything not needed now • Move fast and (hopefully don’t) break (too many) things • Done is better than perfect
