Back in 2017 (feels like ages ago) I decided to take a peek into the ShadowBrokers leaks and reverse some of the tools. I started on dewdrop simply because it had a macOS version. I made local presentations at 0xOpoSec and BSidesLisbon but those slides were never published for obvious reasons (aka live implants all over the Internet). Significant time has passed and everyone went crazy last week with the beautiful NSO exploit VM published by Project Zero, so why not ride the wave and present a simple NSA BPF VM. It is still an interesting work and you have to admire the great engineering that goes behind this code. It’s not everyday that you can take a peek at code developed by a well funded state actor. This post is only going to focus on the BPF part of the implant so you will have to fill in the blanks about everything else.
