Our favorite 5 hacking items

1. Resource of the week

A Glossary of Blind SSRF Chains & GitHub repo

This is a massive post on exploit chains that help escalate the impact of blind SSRF. This is simply a must see for bug hunters, a new amazing resource by @assetnote.

There is also a GitHub repo. You can contribute with additionl techniques by sending a pull request.

2. Writeups of the week

Finding 0day to hack Apple (Apple, $50,000)
Making Clouds Rain :: Remote Code Execution in Microsoft Office 365 (Microsoft)

There’s a bunch of exceptional findings and excellent writeups that were published this week. Make sure to check out the entire writeups section below. These two are the one that caught my attention the most for their impact and interesting technical details.

@rootxharsh and @iamnoooob got Remote Code Execution on three Apple subdomains by analyzing the CMS they use (Lucee). @steventseeley also popped shells but on Microsoft Office 365 and he also bypassed two different patches for the vulnerability.

3. Tools of the week


OpenAPI Security Scanner & Automating Permission Checks Using OpenAPI Security Scanner?

Remember BBRF, @honoki‘s Python tool for storing/querying bug bounty data in a CouchDB database? I’ve been using it and it is an excellent solution for easily handling assets and scopes. Now it also has a Burp plugin that allows you to add domains/URLs to your database from Burp! Fantastic, right?

The second tool is an innovative scanner for automating authorization tests. Logic flaws are notoriously difficult to automate but @ngalongc manages to do just that! His OpenAPI Security Scanner pointed to an API with a set of credentials monitors for changes in permissions and notifies you if any permissions have changed.

4. Video of the week

@Farah Hawa Talks About Learning How to Code, Javascript, Creating Content, Mentorship and more!

Anyone who thinks it is too late to start bug bounties or they don’t have the right technical background should watch this interview. @Farah_Hawaa shares her story and how she got into Web hacking in a relatively short time. She went from journalism / mass media studies to becoming a hacker, triager for a bug bounty platform and content creator. Such an inspiration!

5. Podcast of the week

Day[0] Episode 60 – Breaking Lock Screens & The Great Vbox Escape

Day[0] is already at episode 60 and I’ve just heard of it! I love that it’s not just about generic InfoSec news but also comments on very technical writeups and topics. A really nice discovery!
