## Abstract
Patdown probes a network's DNS servers to determine whether they have resolved domains associated with various EDR/XDR solutions.

**Example**: if a network's resolver has `assets-public.falcon.crowdstrike.com` in its cache, chances are the '*CrowdStrike Falcon*' EDR solution is present somewhere on the network.

These DNS servers can be specified as arguments (the preferred way), or patdown can automatically retrieve and analyze the authoritative nameservers of a target with the `-t` flag.

⚠️  Authoritative nameservers are rarely used as egress recursive resolvers for networks and are not as efficacious for fingerprinting for EDR/XDR.

## Installation
Retrieve a binary corresponding to your architecture from **Releases** 

*or*

`git clone https://git.supernets.org/delorean/patdown.git && cd patdown/cmd/patdown && go build -o patdown main.go && ./patdown`

## Usage
**Help**

`patdown -h`


**Target specific resolvers**

`patdown -n ns1.target.resolver -n ns2.another.target.resolver`


**Automatically snoop authoritative nameservers**

`patdown -t supernets.org`
