FAVICORN 💖🦄

All-sources tool to search websites by favicons.

The mechanism

Favicorn takes a favicon and provides search result links across 10 platforms, and not only.

Drop a ⭐ on the repo, and we’ll add automated scraping for all sources!

Usage

There are 3 search modes:

• search by direct favicon URL;
• search by file;
• and search by domain (guessing possible favicons).

Search by a specific favicon URL (--uri, -u):

./favicorn.py -u https://emojipedia.org/images/favicon-32x32.png

Search by a favicon file (--file, -f):

./favicorn.py -f test-favicon.png

Search by a domain, resolving to IPs and checking their favicons (--domain, -d):

./favicorn.py -d google.com

Additional options

Show favicon hashes for a search (--verbose): ./favicorn.py -d google.com -v

Get additional favicon versions using search engines (--add-from-search-engines, -e): ./favicorn.py -d google.com -e

Save all links to the specific file (-s, --save-links-filename): ./favicorn.py -d google.com -s links.txt

Give tinyurl links instead of full links for platforms: --tinyurl

Show only links to platforms, don't extract preview of results: --no-fetch

Disable unicorn animation (dangerous option, use with caution!): --no-logo

Preview of results

By default, Favicorn generates links to search for websites by their favicon across all known platforms, and then retrieves the first pages of results from some of them.

Currently, ZoomEye, Shodan (key required), and Netlas (key required) are supported.

Export API keys in the following way:

export SHODAN_KEY=...
export NETLAS_KEY=...

Thanks 💜

Thanks for @soxoj, who was an inspirer, muse, auditor of my pure code and for his huge peace of development. Also i'm grateful for one of the most vibrant OSINT communities for testing this project. Do not hesitate to provide something interesting or fix our bugs! But don't forget, it's not a just another boring swiss-knife.
