No video of the event yet, sorry!

The talk will primarily focus on the prevalence of the following types of flaws:

  1. overly permissive application programming interfaces
  2. business logic errors
  3. insecure direct object reference attacks
  4. use of insecure identifiers

Through providing real life examples of discovered issues, the talk will provide a starting point for where and how resourceful OSINT can be found and collected. Further, the talk will also touch upon how developers can avoid baking these issues into their services and products and how end users can avoid becoming a part of these databases. The talk will also cover targeting ‘hyper local’ service providers for the purpose of building categorised data repositories.

  • Talk overview:
  • Introduction:
  • What is OSINT?

  • Numeric Identifiers, API(s), IDOR(s), Weak Auth;
  • Slides with examples
  • Execution: “The good stuff”
  • Scraping the information, OR
  • Creating tools to query at will.
  • Prevention:

  • As users: What to avoid? (protective techniques)
