Hey hackers! These are our favorite resources shared by pentesters and bug hunters last week.
This issue covers the week from 14 to 21 of February.
Our favorite 5 hacking items
1. Video of the week
If you are discouraged by bug bounty and think all the bugs are gone, watch this. @InsiderPhD gives an awesome explanation of why it is not true, and what you need to do to start finding bugs.
I love her way of thinking. She deconstruct the question into several chunks and tackles one after the other: Which targets/industry to choose? Which assets and bugs to focus on? Which techniques to learn? How to interpret and use bug bounty statistics?
2. Writeups of the week
The first writeup is an excellent breakdown of common vulnerabilities of XML and ZIP parsers. @spaceraccoonsec was able to find an XXE and RCE via ZIP path traversal.
Mastering classic techniques can be as lucrative as monitoring and testing for new ones, which is what @parzel2 did. He got an impressive bounty by reporting CVE-2020-0618 on Tesla only 1 day after it was published! I am amazed at his monitoring and historic data management that probably allowed for this speed. But I’m also surprised that the bug was accepted since some programs do not reward for CVEs discovered too recently.
3. Podcast of the week
This episode goes over what happened during the Iowa-Coalfire pentesters debacle.
This is a must for anyone who loves pentest stories, Darknet Diaries, and was concerned over this shocking incident.
4. Tool of the week
This Burp extension automatically highlights or add a comment to requests based on user-defined rules.
Use cases suggested are interesting. The tool allows you to highlight specific status codes, differentiate user sessions for authentication and authorization testing, hide requests with specific HTTP methods (e.g. CORS preflight OPTIONS requests), facilitate SOAP services tests by adding comments, and highlight requests containing sensitive information.
5. Non technical item of the week
Do you know the common point between learning German, crochet world records, knitting, hedge fund management, reading challenges, skydiving, and losing weight by hiking? Stephen Duneier did all that and much much more just by making marginal adjustments to his daily routine.
It is amazing to see these concrete examples of making really ambitious goals and breaking them down into manageable decisions. By making one small good choice after another, the unattainable becomes easily reachable.
I think this is the best approach and mindset whether you’re struggling with bug bounties, some complex hacking techniques, time management, weight loss or anything.
