 Though you will see most of the labs as part of the course and exercises, I would recommend everyone to do a "clean run" after completing the exercises. There are for sure some parts of the lab that you can only discover on your own, which also gives you the opportunity get some more valuable practice in before your exam. 🙂

 I can think of very little improvement points regarding the labs. One of my primary objections is that initial access into the labs can be finnicky at times, and it cannot be bypassed once you already gained access. This is quite annoying if the lab has been reset and you just want to re-establish beacons, only to find that the phishes you sent earlier now stopped working due to infrastructure instability. Luckily, RastaMouse has confirmed that this is something that will be fixed in the next version of the course.

 Truth be told, I was a bit disappointed at how easy the first three flags were in my version of the exam. The fourth flag however provided much more of a challenge and was a welcome change in pace from the others. It should be noted that the course is however marked as a beginner-level course, so I shouldn't complain about the difficulty too much. Obviously, there is no shame in 'only' submitting three flags to pass the exam. However, based on my experience with the exam I would say that everyone who has prior red team operations experience (either working experience or through certs like OSEP) should really challenge themselves to try and submit all four flags - it's definitely worth it!

 The exam doesn't require a report, which is a welcome break to some. I don't mind reporting for exams myself, and honestly it should become routine to take good and report-worthy notes in any case. So, even if it's not strictly required, my strong advice would be to challenge yourself to make a habit of keeping quality notes. If you need some inspiration, I discuss my technique for keeping quality notes and turning them into a report easily [in this blog post](https://casvancooten.com/posts/2020/05/generating-pretty-pwk-reports-with-pandoc-and-markdown-templates-inside/).

 With all that out of the way, let's get to the meat 'n' potatoes of this post - **Nimplant**! Nimplant is what I dubbed the C2, obviously (and very unoriginally) because of the implant written in Nim. As it turns out, I wasn't the first with this idea...

 Nimplant is meant for use as a first-stage implant. This means that it is typically used for an initial infection, before dropping more elaborate malware such as a Cobalt Strike beacon. This use case poses a couple of requirements for the implant:

 When I saw the first positive reviews of the PEN-300 course rolling in, it didn't take me long to enroll in the course. I ordered the 90 days package, since I took the course next to my full-time day job. Unless you can dedicate a lot of time I would probably advise most to do the same, even though it is possible to complete the full course materials and labs in way less time (I completed both in about six weeks). Do note that I completed the course during a Covid-lockdown, which gave me a bit more free time and flexibility in the evenings and weekends. 🙂
