Our favorite 5 hacking items

1. Guide of the week

The Complete Guide to CORS (In)Security by Bedefended

This is a comprehensive guide to CORS for security professionals. It’s the best document that I’ve seen on this subject, covering everything from an introduction to the basics of SOP (Same-Origin Policy) and CORS, to attacks and mitigations, with references to the existing research on this topic.

2. Video of the week

Christina Camilleri: Security Solutions Specialist for Riot Games | Play Makers Episode 6 by Travis Gafford

Wow, I could not get my eyes of Christina during this interview. I’m usually not into “My path to infosec”-type interviews but this one is fascinating: She shares stories of physical pentests, insights into social engineering, why security is so important for a video game company… all with glimmering eyes that are a testament to her passion!

3. Writeup of the week

Remote code execution by hijacking an unclaimed S3 bucket in Rocket.Chat’s installation script. by @EdOverflow

This is a simple bug but very creative!

My main takeway is to always carefully read the source code if you have access to it.
In the latest release of Rocket.Chat, an install.sh script contained a curl request to retrieve a file from an unclaimed S3 bucket. So by creating a bucket with the same name, Ed could make users download any files from his bucket.

4. Tool of the week

getsploit by @VulnersCom

This is a simple but useful command-line tool to search for vulnerabilities listed in vulners.com, the same way searchsploit searches for vulnerabilities in exploit-db.com.

5. Non technical item of the week

AWS Slurp Github Takeover by @SweetRollBandit

This is a good reminder to always read the source code of github repositories before executing any script file in them.
That said, if anyone has a copy of the real Slurp repo, would you please send it to me? I couldn’t find it anywhere!
