sigurlfind3r: A Passive Reconnaissance Tool for known URLs Discovery

A passive reconnaissance tool for known URLs discovery – it gathers a list of URLs passively using various online sources.

Features

• Fetches known URLs from AlienVault’s OTX, Common Crawl, URLScan, Github and the Wayback Machine.
• Fetches disallowed paths from robots.txt found on your target domain and snapshotted by the Wayback Machine.
• Regex filter URLs.
• Save output to file.

Installation

From Binary

You can download the pre-built binary for your platform from this repository’s releases page, extract, then move it to your $PATHand you’re ready to go.

From Source

sigurlfind3r requires go1.14+ to install successfully. Run the following command to get the repo

GO111MODULE=on go get -u -v github.com/signedsecurity/sigurlfind3r/cmd/sigurlfind3r

From Github

git clone https://github.com/signedsecurity/sigurlfind3r.git && \
cd sigurlfind3r/cmd/sigurlfind3r/ && \
go build; mv sigurlfind3r /usr/local/bin/ && \
sigurlfind3r -h

Post Installation

sigurlfind3r will work after installation. However, to configure sigurlfind3r to work with certain services – currently github – you will need to have setup API keys. The API keys are stored in the $HOME/.config/sigurlfind3r/conf.yaml file – created upon first run – and uses the YAML format. Multiple API keys can be specified for each of these services.

Example:

version: 1.4.0
sources:
    - commoncrawl
    - github
    - otx
    - urlscan
    - wayback
    - waybackrobots
keys:
    github:
        - d23a554bbc1aabb208c9acfbd2dd41ce7fc9db39
        - asdsd54bbc1aabb208c9acfbd2dd41ce7fc9db39

Usage

DiSCLAIMER: fetching urls from github is a bit slow.

sigurlfind3r -h
