Bug Bytes is a weekly newsletter curated by members of the bug bounty community. The first series are curated by Mariem, better known as PentesterLand. Every week, she keeps us updated with a comprehensive list of all write-ups, tools, tutorials and resources we should not have missed.

Hey hackers! These are our favorite resources shared by pentesters and bug hunters last week.
This issue covers the week from 26 of April to 3 of May.

Our favorite 5 hacking items

1. Video of the week

5 super important main-app testing tips for bug bounty hunters with STOK&Haddix

Any video by @stokfredrik & @jhaddix is a must watch! This one has 5 crucials things you want to do as a bug hunter:

  • Don’t limit yourself to the external attack surface. Log in as different users & try to find where the sensitive functionality is => access controls bugs & IDOR

  • Find out how the site references you as a user (& what you’re allowed to do) => IDOR, File upload, RCE

  • Test all parameters => SSRF, LFI, RFI, Path traversal

  • Content discovery => hidden paths, private data leakage => Authentication bypass, logic flaws

  • Find out which business flaws the target cares about (other than technical bugs)

But this is not all. Watch the video. It’s short but full-packed with information!

2. Conference of the week

Nullcon Goa 2019, especially:
Best Of Google VRP 2018
How To Use Bug Bounty To Start A Career In Silicon Valley
Automating Security Testing with Functional Testing Test Cases
Getting to $10,000 – the variables at play in determining bounty awards
Introducing the ASVS 4.0
Interview with Robert Baptiste aka Elliot Alderson [@fs0c131y]

I really recommend watching the talk “How To Use Bug Bounty To Start A Career In Silicon Valley”. It has awesome advice on leveraging bug bounty hunting to build a solid resume and find a job in Silicon Valley (or anywhere else). This includes which bugs and programs to focus on, which pitfalls to avoid, etc.
“Best Of Google VRP 2018” is also a good resource for bug hunters who want to succeed with Google VRP. Some of the advice applies to other programs too (like specializing in a product/attack vector).

3. Article of the week

Meet the Hacker: Inti De Ceukelaire – “While everyone is looking for XSS I am just reading the docs.”

This is an excellent interview of @securinti. What I like about it most is that the interviewer, @\_zulln, is also a hacker. So unlike most interviews of this sort, the questions and answers are very technical and mindblowing for anyone starting out as a bug hunter.
I highly recommend this read if you want to find out what sets apart successful bug hunters from beginners.
Here are some interesting excerpts:

  • “Many hackers look for bugs, I look for attack scenarios and then for the bugs. And it works for me as I get fewer duplicates. The downside is that I spend time researching ideas that sometimes yield nothing.”

  • “Scanners do not detect logical bugs, because to detect them you need context, you need to understand the application and the business logic. While everyone is looking for XSS I am just reading the docs.”

4. Resource of the week

Android App Reverse Engineering 101

If you’re interested in Android app hacking, checkout this workshop. It’s about reverse engineering Android apps and includes both theory and exercises. Just awesome!

5. Non technical item of the week

Mental Health and Security

So many hackers suffer from at least of the mental struggles mentioned in this article: imposter syndrome, burnout, anxiety and depression.
I hear/read more and more testimonies on this especially on Twitter, and I have similar experience myself. Hacking involves so much learning/change/stress…
So it’s nice to know that I am/we are not alone in this. And it is helpful to read a fellow hacker’s perspective on these issues, and how he deals with them.

6. Intigriti News
