PentesterLab Pro Review

Recently I started a new job where a portion of my work was related to Application Security. I have done a number of web application assessments before, however it has always been my weakest area. I have read most of the usual web application testing resources which you can find listed here. I have also submitted to bug bounty programs, so the only material I felt I could benefit from were labs. I needed something hands-on that covered a wide range of web vulnerabilities and real world web exploit scenarios.

PentesterLab is a set of exercises downloaded as ISO’s which include course material that can be worked through to expand one’s skillset. I personally started with the free material and even used the ISO’s to create tools. After completing a number of the ISO’s, I noticed some very intriguing material was released for the Pro edition. I decided that getting the Pro subscription was more than worth it, so I signed up.

Navigating the Site

Once I logged in, I was greeted with a straightforward interface and a clear path to further develop my skillset. I started with the Introduction Badge which familiarized me to the scoring system and a few web fundamentals. Much of the material wasn’t new to me, but it is an excellent building block for anyone new to web application penetration testing:

Essentials Badge

The Essentials Badge section is where I really started to improve my skills. This section contains 60 exercises covering the following topics:

  • Authorization issues
  • Code Execution
  • Command Execution
  • Directory Traversal
  • File Includes
  • LDAP Injection
  • MongoDB issues
  • Open Redirection
  • SQL Injection
  • SSRF [Server Side Request Forgery]
  • SSTI [Server Side Template Injection]
  • File Upload Vulnerabilites
  • XML Injection
  • XSS [Cross Side Scripting]

Anybody who does web application testing will tell you that this list of exercises is a great foundation for moving into web application penetration testing or just improving your bug hunting skills. By moving through these exercises, I was able to increase my understanding of web technologies, increase my ability to use tooling to solve challenges, and also get hands-on experience with a plethora of vulnerability types.

All of these exercises can be found in the Essentials Badge section and are are tracked and hosted online, which makes them accessible everywhere. I was able to login effortlessly at home or work to complete challenges:

Certificates of Completion

When you complete these challenges, you are issued a certificate of completion. These are both a nice trophy for yourself and something you can show to potential or current employers. These certificates are easily accessible in your account at all times:

After working through these exercises, you build a strong foundation to move on to the other exercises. These are longer, more challenging exercises that contain real-world exploit scenarios. These are ranked by difficulty, so you can guide your own learning and gradually build up your skills. New exercises are added frequently, making this a modern and challenging experience. Small hang ups can teach you the little details that are necessary in testing web apps.

Final Thoughts

Overall, PentesterLab Pro is a great experience. I recently completed the Essentials Badge along with a few of the longer exercises. This has taught me quite a bit already. I can also say that I have used some of these techniques in my daily work. The price is also very reasonable compared to other training.
