1. Slide/Tool of the week

Manual JavaScript Anaylsis Is A Bug & MetaSec.js

I hope this talk’s video will be released soon. But even without it, this presentation is very helpful in understanding what to look for in JavaScript files, existing tools for automation, and what can/cannot be automated.

Techniques mentioned include endpoint discovery, reversing source maps, technology fingerprinting, detecting sources and sinks, detecting ReDoS, detecting secrets, detecting vulnerable third-party components, etc.

As a bonus, LewisArdern provides MetaSec.js, a wrapper around several open source tools to automate JS file analysis.

1. Tutorial of the week

How to find more IDORs

This tutorial explains how to find IDORs that are less obvious than just incrementing an ID. The techniques mentioned can be very helpful especially in the context of bug bounty.

Some of them are testing encoded & hashed IDs, adding an ID to the request even if the app didn’t ask for it, changing the request method, etc.

Also, IDOR and self-XSS combined can lead to stored XSS, increasing the impact of the IDOR.

1. Video of the week

Hacking Gotham University

Watch @uraniumhacker hack a fake university for 2 hours. The vulnerable subdomains (and ports) don’t seem to be up anymore, but it’s an excellent walkthrough on hacking Web apps and APIs.

@uraniumhacker explains his methodology, what to look for at each step, how to exploit bugs like SSRF on Jira, IDOR, RCE, how to take notes with screenshots and proofs during the whole pentest process, etc.

1. Conference of the week

DerbyCon 9, especially:

DerbyCon 9 had so many good talks! I’m particularly interested in the ones on CORS, Kerberoasting, WebSOckets, GraphQL, Serverless, API security & red teaming, but many other topics were discussed.

Too bad, this was the last DerbyCon conference!

1. Non technical item of the week

Economics of the bug bounty hunting

This is a great read about how @dmi3sh uses specific metrics to increase his hourly rate as a full-time bug hunter.

The main takeaway for me is that he relies on a list of criteria to decide on which target, functionality and bug type it is best to focus. These are things like: Probability of finding a bug, payout, chance of being duped, of getting N/As and out of scope, chances of being paid, etc.

Using these objective elements helps make decisions about what to focus on a lot easier.
