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 31 of May to 07 of June.
Our favorite 5 hacking items
1. Tool of the week
Keye is a really useful recon tool. It’s the first one I’ve come across that allows hackers to easily monitor changes in URLs.
It’s written in Python with SQLite3 integrated. You give it a list of urls, and run it periodically (using Cron for example). It then requests the urls and detects changes based on the responses’ Content-Length. You can also receive Slack notifications when changes are detected.
2. Writeup of the week
I love the way he explains what he did step by step, from detecting which extensions are allowed and which filters are in place, to bypassing them and executing an XSS. A worthy read!
3. Slides of the week
It’s 453 slides detailing everything: which OS/VMs you need to install (including Kali, Metasploitable 2, Firewall with pfSense, SIEM with Splunk…), how to do it, how to automate OS updates, intro to virtualization, which software you need on each OS (Linux, OS X & Windows) and much more.
I wish I had this when I had just started out. Such a time saver!
4. Conference of the week
Armaan (@armaancrockroax) got [$21,000](https://twitter.com/armaancrockroax/status/1134664934518808576) from bug bounty last month. So when he talks about automation, I’m all ears!
In this talk, he shows how he:
- combines multiple tools to enumerate subdomains
- resolves and sorts subdomains
- finds Jenkins with Shodan
- gets Slack notifications for all scans
- found a Jenkins RCE in Verizon using this same testing methodology
This is a short, sweet and very practical talk. Code snippets are also provided (check out the slides).
5. Video of the week
This is an awesome resource for junior penetration testers (and students who want to become professional pentesters). It provides a pentest report template and goes through each page and detail to explain the reasoning behind it.
Of course, this is not meant to be copied and used as as… Every company uses custom report templates for a reason: they tend to elvolve mission after mission, following client feedback and any new ideas that you have.
But this template is an excellent basis. It contains all the important sections and information you want to convey to clients.
6. Intigriti News
6.1 El Punto Group – a New Responsible Disclosure by Kinepolis
Kinepolis recently acquired the Spanish cinema group “El Punt” with the “Full” cinema complex in Barcelona and “El Punt Ribera” in Valencia. Their websites are often the first point of contact with their costumers. The customers can fetch an overview of currently playing movies and buy their movie tickets. El Punto Group’s ticket sales rely heavily on Kinepolis’s online platform which is why they allow you to research these website and to report any vulnerabilities you may have found.
6.2 Napoleon Games is challenging you!
Napoleon Games is the Belgian leading gambling website where you can play several types of games: casino games, live casino games, sports betting etc. Their biggest concerns are leaks or in game manipulations! That’s why they need you! Can you increase your chances of winning?
Disclaimer: Stay ethical! Before you start hacking, register yourself to the platform, become vetted and request your Napoleon Games test account.
