Cryptographically strong Math.random(). Generate cryptographically strong random float between 0-1. Uses 52 bits instead of 32.
function random(): number {
const buffer = new ArrayBuffer(8);
const bytes = crypto.getRandomValues(new Uint8Array(buffer));
// sets the exponent value (11 bits) to 01111111111 (1023)
// since the bias is 1023 (2 * (11 - 1) - 1), 1023 - 1023 = 0
// 2^0 * (1 + [52 bit number between 0-1]) = number between 1-2
bytes[0] = 63;
bytes[1] = bytes[1] | 240;

Instance Metadata

Cloud metadata

Many cloud providers such as Amazon AWS, Digitalocean and Vultr provide an instance metadata service.

Guest instances can discover their own parameters by accessing an API. By convention, this API is accessible from the address 169.254.169.254

To get the value of key 'k', we send an HTTP request to the relative location /$k If the key corresponds to a tuple, the request is rewritten to key/ which is an index. If no value or tuple exists, it simply returns not found

My tips for finding security issues in GitHub projects.

GitHub for Bug Bounty Hunters

GitHub repositories can disclose all sorts of potentially valuable information for bug bounty hunters. The targets do not always have to be open source for there to be issues. Organization members and their open source projects can sometimes accidentally expose information that could be used against the target company. in this article I will give you a brief overview that should help you get started targeting GitHub repositories for vulnerabilities and for general recon.

Mass Cloning

You can just do your research on github.com, but I would suggest cloning all the target's repositories so that you can run your tests locally. I would highly recommend @mazen160's GitHubCloner. Just run the script and you should be good to go.

$ python githubcloner.py --org organization -o /tmp/output

Decompress FlateDecode Objects in PDF
#!/usr/bin/env python3
# This script is designed to do one thing and one thing only. It will find each
# of the FlateDecode streams in a PDF document using a regular expression,
# unzip them, and print out the unzipped data. You can do the same in any
# programming language you choose.
#
# This is NOT a generic PDF decoder, if you need a generic PDF decoder, please
# take a look at pdf-parser by Didier Stevens, which is included in Kali linux.
