How we test it

Our operators follow a structured checklist for this topic, adapted to your API surface and authentication model.

Testing approach

  • These are attacker-controlled inputs entering the application
  • During code review, first identify where untrusted data comes from.
  • The most important concept in secure code review: Example:
  • A sink is a dangerous function where attacker-controlled data becomes exploitable.
  • String concatenation is used
  • Prepared statements are missing
  • Input validation is absent
  • Remote Code Execution (RCE)
