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.

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.

Writing custom fx syntax rules

An example of using fofa to collect information about a target is given below.

generates a template

A template file is generated by using -g and specifying the path to the generated file name.

fofax -g .config/fofax/fxrules/info-gathering.yaml

      ____        ____       _  __
     / __/____   / __/____ _| |/ /
    / /_ / __ \ / /_ / __ `/|   /
   / __// /_/ // __// /_/ //   |
  /_/   \____//_/   \__,_//_/|_|

2021/12/24 20:09:27 [INFO] Will Write Plugin file: .config/fofax/fxrules/info-gathering.yaml

Check this yaml file, its contents are as follows.

id: fx-2021-01
query: 查询的字符串用于fx="jupyter Unauth" eg:(jupyter Unauth)
rule_name: 规则名称 eg:(jupyter 未授权)
rule_english: jupyter unauthorized
description: 规则描述
author: 作者<邮箱>eg:(xiecat)
fofa_query: fofa语句 eg:(body="ipython-main-app" && title="Home Page - Select or create a notebook")"
tag:
- 标签1 eg(unauthorized)
- 标签2
source: 语句来源

Follow the above instructions and modify the corresponding content to bring in a new fx syntax rule, regarding the path of this file, please put it in the directory ~/.config/fofax/fxrules/ after it is written.

For easy reproduction, the details are as follows (note that the title is filled with your target name)

id: fx-2021-01
query: redteam-info-gathering
rule_name: 红队信息收集
rule_english: redteam-info-gathering
description: 使用fofa针对某个目标进行红队常见的高关注CMS/OA系统的信息收集
author: xiecat
fofa_query: title="Target" && (title="平台" || title="OA" || title="系统" || title="协同" || title="办公" || title="致远" || title="泛微" || title="用友" || title="管理" || title="后台" || title="登录" || title="login" || title="admin") && country="CN"
