Speaker's talks

  • Hacking PHP applications from scratch

    Workshop Intermediate

    Security is a tedious cat and mouse game, that’s increasing in development speed and complexity every single day. Hackers’ game plan is to know more about certain edge cases and in-depth details regarding the technologies they’re attempting to compromise, than the developers who initially built and are currently maintaining those technologies.

  • How your PHP application can get hacked, and how to prevent that from happening?

    Regular talk Intermediate

    In this talk, we’ll exploit some commonly known vulnerabilities (OWASP top 10) and misconfigurations that can occur to a PHP application running on a Linux based host.
