patdown

EDR/XDR (Endpoint Detection & Response) fingerprinting utility useful for predicting defense mechanisms in use on remote systems.

Abstract

Patdown probes 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

Usage

Help patdown -h

Targeting specific resolvers patdown -n ns1.target.resolver -n ns2.another.target.resolver

Automatically snoop authoritative nameservers patdown -t supernets.org
