October 14, 2020

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 04 to 11 of October.

NEW HOODIES: Embrace the hacker stereotype, but do it with style!

Our favorite 5 hacking items

1. Videos of the week

Unicode vulnerabilities that could byͥte you (Part of NorthSec 2020)
Masonhck3571 Talks About Being Disciplined, His Learning Process, and Full Time Bug Hunting!

These are two very informational videos. One is on Unicode vulnerabilities including the latest research such as HostSplit and HostBond attacks. The other is an interview with @Masonhck3571 on transitionning from a non IT job to full-time bug hunting, how he chooses targets, his learning process, etc.

2. Writeups of the week

We Hacked Apple for 3 Months: Here’s What We Found

What an incredible writeup! A crew of five bug hunters (@samwcyo, @bbuerhaus, @nahamsec, @erbbysam and @StaticFlow) hacked on Apple for 3 months and found 55 vulnerabilities. They shared how it went, the list of vulnerabilities detected, with detailed writeups on 12 of them. It’s so impressive when you know that some of them have full-time job and not all the bugs were disclosed (maybe including some new research).

As @hakluke says, an apple doesn’t taste as good now, it just tastes like vulnerabilities.

3. Tools of the week

bbrf-client & Intro
jwt-heartbreaker & Intro

BBRF is Pieter Hiele’s (@honoki) tool for storing bug bounty data. It is in Python, uses CouchDB and has a client-server architecture. It is meant to be combined with other recon tools to store/read the data collected on a program (subdomains, domains, IPs…). A very handy and well-documented tool!

JWT is a Burp extension to passively scan for JWT tokens signed with a weak secret. I haven’t tried it yet but it looks interesting, especially if customized to even more JWT secrets to test.

4. Article of the week

Evading defences using VueJS script gadgets

This is an excellent article on XSS in VuesJS. It is packed with information on identifying and exploiting XSS created from VueJS script gadgets. A must if you’re into XSS or plan on testing VueJS sites!

5. Tutorial of the week

Salesforce Lightning – An in-depth look at exploitation vectors for the everyday community

Aaron Costello (@ConspiracyProof) published this in-depth tutorial on hacking Salesforce Lightning by exploiting common misconfigurations of the CRM. This offensive approach hasn’t been documented before, so it is very interesting for bug hunters and pentesters.
