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. You can sign up for the newsletter here.

Hey hackers! These are our favorite resources shared by pentesters and bug hunters last week.
This issue covers the week from 25 of January to 01 of February.

Our favorite 5 hacking items

1. Conference of the week

BSides Leeds 2019, especially:
Confessions Of A Bug Bounty Triager & Slides
So You Want To Be A Pentester?
Hacking Companies For Internet Glory While Not Dying In A Sarlacc Pit
A Pentester’s Guide To Left Shifting Security

These are four very interesting talks. They’re respectively about:

  • Questions & tips from a bug bounty triager for both bug hunters & companies/triagers;
  • Advice for anyone looking for a pentester job from the CEO of a pentesting company;
  • Differences between bug bounty & pentesting;
  • Ideas from a pentester on how to integrate pentesting into the development process. Automating some tests helps detect vulnerabilities early in the development lifecycle.

2. Writeup of the week

Guest blog: Eray Mitrani – Hacking isn’t an exact science

This is a great writeup on a simple bug that affects some misconfigured Jira instances.
When a new dashboard or shared filters are being set up, they can become inadvertently accessible without authentication if permissions are set to “everyone”. You can test, for instance, if the status endpoint is accessible by trying /status/, then if it doesn’t work try /status/..;/.
What I love about this writeup is how @ErayMitrani ‏explains two fundamentals processes for bug hunters:
  • How to apply someone else’s research to find new bugs on bug bounty programs even if you don’t understand the bug 100%;
  • How organizing his bug hunting notes allows him to go back and look for new bugs in programs he tested previously.

3. Tutorial of the week

SSRF — Server Side Request Forgery (Types and ways to exploit it) Part-3, Part 2 & Part 1

This is a great series of blog posts on SSRF. It’s very practical and explains the types of SSRF bugs, how to exploit them, how to bypass filters, and example of vulnerable sites.
FIY, some of the vulnerable sites were found with Shodan. These bugs were probably not disclosed to the sites’ owners which I think is illegal. So please do not exploit them.

4. Challenge of the week

DomGoat Client XSS exercises

DOM XSS can be harder to detect and exploit than traditional XSS. This is because everything happens client-side. The payload isn’t sent to the server and reflected back in the response. So the best way to detect them is reviewing code and most tools aren’t that good at it (at least not as good as manual code analysis).
This challenge can help you understand sources and sinks usually involved in the exploitation of DOM XSS bugs. There are 10 exercises with the vulnerable code highlighted.

5. Non technical item of the week

Tips on how to live with imposter syndrome

A lot of hackers suffer from imposter syndrome, me included. I think it’s because the more we learn, the more we know we don’t know. We also have to be both versatile and specialists, which is hard because infosec/hacking has so many different vast subcategories.
If you get imposter syndrome too, then I recommend this article. It offers advice and practical tips to manage it and don’t let it hold you back.
