About GrepAddr

GrepAddr takes input from stdin and extracts different kinds of addresses from stdin like URLs, IP addresses, e-mail addresses, MAC addresses and more. Essentially it's grep, but for interesting addresses.

Because the script uses regexp, it's very common to get false positives for FQDNs.
The options --resol only) --iana and --private can be used to reduce the number of false positives.

Why use GrepAddr?

Several tools and scripts exist on the internet which similar functionality but usually only for a single address type, for example xurlsx, xpath-url-extraction and relati. Little/none of them can grep as many addresses type like GrepAddr can. You can use GrepAddr when doing a pen test or CTF, or when persuing a bug bounty.

Install

GrepAddr should be able to grep addreases with a default Kali Linux installation without installing additional Python packages.
Just run:

When using the installer in an automated en, use the following command for an automated installation:

If you're running into trouble running GrepAddr, please drop me an issue and I'll try to fix it :)

Usage

Examples

It's really easy to grep all supported addresses from stdin, just run:

Want to extract addresses of certain type? Choose one of the options, for example -mac and run:

Want to grep FQDNs with a private TLD, just run:

Want to extract FQDNs and show only resol URLs needed to be decoded first, just run:

Want to grep all addresses with the least chance of false positi having to wait for resolving FQDNs:

Want to extract all addresses and convert relative URLs starting at the root to an absolute URL:

Want to extract addresses from a binary, use it together with strings:

When looking for URLs from the current user hi Windows' registry, run these commands:

Within Windows:
