Our favorite 5 hacking items

1. Video of the week

Lets be a dork and read .js files with zseano

JavaScript analysis is a very important step when testing the security of a website. If, like me, you never were a programmer and struggle with this, then this video is a must!

@zseano walks us through what to look for in them and how, plus an introduction to Google and Github dorks.

2. Resource of the week

XXE Cheat Sheet - SecurityIdiots

This is a nice cheetsheet to help with XXE detection, exploitation and Out-Of-Band exploitation, and WAF bypass. A good reference!

3. Article of the week

A Tale of Exploitation in Spreadsheet File Conversions

Do you remember this awesome video snippet with @daeken where he was clapping because obviously some kind of exploit or bug worked? It turns out that he was working on a Ghostscript payload in LibreOffice, in collaboration with @bbuerhaus, @smiegles, and @erbbysam.

It did work, and this is the writeup of the whole research that led to that bug. It touches on many topics: Ghostscript, fingerprinting LibreOffice, LFD, SSRF… This is worth reading and a great example of research in Web app security.

4. Non technical item of the week

A well curated 60s playlist for those slow Saturday mornings

This is a really cool playlist. 100% Stök, only happy vibes. I’ve been listening only to Deep House & Electro mixes (from Kygo, Dj Drop G…), so this is a refreshing change.

5. Tool of the week

CSP

Retrieving a list of whitelisted hosts from CSP headers is not a new recon technique. But the novelty with this tool from @EdOverflow is that it automates the process.

You can get a list of hosts with a one-liner, and feed it to your other tools.
