Hey hackers! These are our favorite resources shared by pentesters and bug hunters last week.
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.
This issue covers the week from 07 to 14 of February.
Our favorite 5 hacking items
1. Video of the week
Lately, @zseano has been quieter than before. So, it is nice to hear him share insights on his recon process (e.g why he runs subdomain tools last), his hacking methodology, why he closed Bug Bounty Notes, and much more.
2. Resource of the week
Its creators, @RandoriSec, have also been sharing a lot of excellent tips for mobile hacking on Twitter. It’s worth checking out.
3. Webinar of the week
I love that he explains the reasoning behind each idea. For instance, why reporting alert(1) for XSS is never the best idea, or why you should really not use sublist3r on its own for subdomain enumeration.
4. Non technical item of the week
5. Tutorial of the week
Have you ever run a command line tool and wondered which requests it was sending to your target? Knowing this can be valuable for pentesters and bug hunters. It helps understanding what the tool does.
The solution detailed in this excellent tutorial is to use Burp Suite as a proxy. The process is explained for curl, wget, Java JARs, Python, Node JS and Go binaries.
Another advantage of using Burp is that all requests sent are logged (with request and response times).
I can’t tell you how many times pentest clients asked for what was being tested at X time and the number of requests, because they noticed network or server issues and wanted to determine if it was caused by the tests.
