Advanced web hacking training

3 day training class

This fast-paced training class gives attendees an insight into advanced web hacking. The team has built a state-of-the-art hacklab and recreated security vulnerabilities based on real-life penetration tests and real bug bounties seen in the wild.

The course is available directly from Claranet Cyber Security or you can book through one of our partners. The course is now available as live, online training and can be delivered for you individually or for your company. Contact us below with your requirements.

Much like the advanced infrastructure hacking training class, this class talks about a wealth of hacking techniques to compromise web applications, APIs and associated endpoints. This class focuses on specific areas of app-sec and on advanced vulnerability identification and exploitation techniques (especially server side flaws). The class allows attendees to practice some neat, new and ridiculous hacks which affected real-life products and have found a mention in real bug-bounty programs. The vulnerabilities selected for the class either typically go undetected by modern scanners or the exploitation techniques are not so well known. Attendees can also benefit from a state-of-the-art hacklab and we can provide 30 days lab access after the class, to allow attendees more practice time.

Learning Objectives:

  • Modern JWT, SAML, oauth bugs
  • Business logic and crypto flaws
  • RCE via Java Serialisation, Object, OGNL and template injection
  • Exploitation over DNS channels
  • Advanced SSRF, HPP, XXE and SQLi topics
  • Attack chaining and real life examples

This fast-paced class gives attendees an insight into advanced web hacking. The team has built a state of the art hacklab and recreated security vulnerabilities based on real-life Penetration Tests and real bug bounties seen in the wild.

Attack chaining

Combining Client-side and or Server-side attacks to steal internal secrets


Whoever works with or against the security of modern web applications will enjoy and benefit from this class.

This is not a beginner class and attendees are expected to have a good prior understanding of the OWASP top 10 issues to gain maximum value from the class. Further to this, the class does not cover all AppSec topics and focuses only on advanced identification and exploitation techniques of the vulnerabilities.
