Basic FOFA syntax queries
Icon Hash local/online calculation query
Asset filtering
Opening in browser
Linking other security tools
More (waiting for your feedback after using) ......

In addition to this it is possible to customize fx syntax queries, and users can write their own specific fx query rules via a configuration file in yaml format.

0x01 Download

Click on the Release download link and choose the appropriate release for your system architecture.

0x02 Configuration

macOS/Linux

Unzip the downloaded fofax archive and recommend placing it in the /usr/local/bin/ directory, so that you can run fofax commands from any directory.

tar -zxvf ~/Downloads/fofax_v0.1.11_darwin_amd64.tar.gz -C /usr/local/bin/.

The first time you run the fofax command a configuration file is automatically generated, located at ~/.config/fofax/fofax.yaml.

fofax

                         fofax.xiecat.fun

2021/12/23 21:21:28 [SUCC] create config file /Users/user/.config/fofax/fofax.yaml. please modify and use

The next step is to configure this configuration file. Generally you only need to configure email and key.

vim ~/.config/fofax/fofax.yaml

# fofa api email
fofa-email: ******@gmail.com

# fofa api key
fofakey: ***************

Windows

Unzip the archive and run fofax.exe for the first time to generate a fofax.yaml configuration file in the same level directory. Then open this configuration file and fill in email and key.

Basic queries

There are two ways to query app="APACHE-Solr", which will output 100 hosts by default without specifying the number, and will de-duplicate the data by default.

Calculate icon hash and query

There are two ways to do this, the first is to query directly based on the URL that provided the icon.

The second one is to calculate hash and query based on local icon file.

0x04 fx syntax query

When using fofa to do information collection or other things, it is possible that the query statement will be very, very long and not easy to remember, so we can't just take a small book to remember the fofa query statement.

This time, you can use fofax's fx function. Currently fofax has dozens of built-in fx syntax query rules, users can directly use the corresponding parameters to query. You can also write your own specific fx syntax query rules via yaml format configuration file.
