Squeezing the juices out of robots.txt.

A fully automated workflow that you've never seen before.

(thread)
1. This script scrapes the disallowed paths from the robots.txt files of a list of domains and saves them to a single file. It also removes any unwanted entries and sorts the file in a particular way.

Can you write it yourself? Here’s how the script should look like.
2. Create a directory called "massrobots" in the pwd. This is where you'll save all the robots.txt files for later processing.

2023 Hacker's Guide: How to Break into Pentesting and AppSec.

(thread)
1. Hands down, one of the best practical resources is @RealTryHackMe. I would take the "Complete Beginner" learning path, then the "Jr. Penetration Tester" path. It will get you off the ground in no time.

2. Simultaneously, I would practice at @PortSwigger Academy. Personally, I'd focus on all things Broken Access Control.

The most frequent vulns I found in 80+ pentests in 2022.

(thread)
1. Rate Limit Bypass

In more than half of the pentests I conducted, I found that there were no rate limits imposed on login functions or authentication mechanisms. This lack of rate limiting, combined with weak password policies, can lead to accounts being easily compromised.
2. Session Token not Invalidated upon Logout

This vuln is caused when the session token is not invalidated at user logout. If the validity of the token or the time to expiry is long, this can lead to the token being leaked, potentially resulting in a data breach or other vulns.
