Our favorite 5 hacking items

1. Article of the week

Scope Based Recon Methodology: Exploring Tactics for Smart Recon

You might’ve already seen Harsh Bothra (@harshbothra_)’s past talks on this same topic. This is a nice complement that includes a recon methodology with three options based on the program’s scope (small, medium and large), links to tools and a summary mindmap.

2. Writeup of the week

OAuth Misconfiguration Leads to Full Account takeover

This is an interesting finding by Yasser Mohammed (@boomneroli). It starts with OAuth CSRF that doesn’t work despite a missing CSRF token, debugging it with postMessage-logger, and ends up being a cool bug chain involving OAuth CSRF, postMessage and Clickjacking leading to account takeover.

For other cool writeups, also keep an eye on @Samm0uda who started sharing some of his 50 bugs found in Facebook.

3. Tutorials of the week

Finding More IDORs – Tips And Tricks
The Lone Sharepoint

Who doesn’t like IDOR? The first tutorial goes over several IDOR techniques to check on ID parameters and API calls.

The second article is a nice collection of Sharepoint attacks that might come in handy during a pentest?

4. Tool of the week

Confused

Short after the new dependency confusion writeup was published, @joohoi shared this tool that automates checking for it. It is in Go and currently supports three package managers (pypi, npm and composer).

5. Resource of the week

Language Agnostic Security Code Review

This article provides a language-independent methodology for security code review. Of course, the more knowledge you have of a programming language, the better code review you can do but this is a good start. It’s a basic methodology to build upon with experience.
