Bug Bytes is a weekly newsletter curated by members of the bug bounty community. The first series is curated by Mariem, better known as PentesterLand. Every week, she keeps us up to date with a comprehensive list of write-ups, tools, tutorials and resources.
Hey hackers! These are our favorite resources shared by pentesters and bug hunters last week.
This issue covers the week from 08 to 15 of November.
We launched another XSS challenge! You can win a Burp Suite Pro license if you solve it before Monday. Check it out:
We're celebrating 10K followers with a challenge! 🎉

Our favorite 5 hacking items
1. Conference of the week
Finally, DEF CON 27 videos are released! There is no introduction needed, right?
I’m watching this first: “Owning The Clout Through Server Side Request Forgery” by @NahamSec & @daeken. What about you?
2. Resource of the week
It explains everything from recognizing and reading JWTs, an attack methodology, how to test for known exploits, fuzzing, stealing JWTs by exploiting other vulnerabilities, and more. An excellent resource to get into hacking JWTs!
3. Challenge of the week
Personally, I also plan on using it as a challenge to practice finding secrets on Github.
4. Non technical item of the week
This is @mattiacampagnan’s story on how he found a pentesting job. Basically, he created a blog and wrote dozens of articles related to penetration testing. This gave him some exposure. A company contacted him for an interview, he got a remote part-time position, did the work for 3 months, and finally it became a full-time position.
I loved reading this story because it is another reminder that there is no secret way to success. Do your work and find a way to differentiate yourself. Simple, but a lot of people do not want to hear that…
I personally can attest to the same thing: Maintaining a blog and being consistent opens up so many possibilities and professional options. If you are struggling to find work, you should really consider starting a blog, video course or Youtube channel. Anything that you put out there that shows technical abilities and professionalism will help you find employers or customers.
5. Tutorials of the week
These are two nice tutorials that go a bit further that most typical recon articles.
Apart from classic subdomain enumeration, they show how to programmatically fetch URLs with their status code & page title, and search results for keywords. This will certainly aid process data collected from large scope bug bounty programs (or pentest targets).
