Uncover

Uncover by Projectdiscovery lets you quickly discover exposed hosts on the internet using multiple search engine. It consists of a go wrapper using APIs of well known search engines to quickly discover exposed hosts on the internet. It is built with automation in mind, so you can query it and utilize the results with your current pipeline tools. Currently, it supports shodan, censys, and fofa search engine.

This can be a Bug Bounty Hunter’s sidekick, to quickly start gathering specific and targeted services and products essentially making you faster in discovering bugs that let’s you focus on the PoC and impact.

Features

• Simple and Handy utility to query multiple search engine
• Multiple Search engine support (Shodan, Censys, Fofa)
• Automatic key/credential randomization
• stdin / stdout support for input and output

Installation Instructions

uncover requires go1.17 to install successfully. Run the following command to get the repo –

go install -v github.com/projectdiscovery/uncover/cmd/uncover@latest

Usage

uncover -h

This will display help for the tool. Here are all the flags it supports:

Usage:
  ./uncover [flags]

Flags:
INPUT:
   -q, -query string[]   search query or list (file or comma separated or stdin)
   -e, -engine string[]  search engine to query (shodan,fofa,censys) (default shodan)

CONFIG:
   -pc, -provider string  provider configuration file (default "$HOME/.config/uncover/provider-config.yaml")
   -config string         flag configuration file (default "$HOME/.config/uncover/config.yaml")
   -timeout int           timeout in seconds (default 10)

OUTPUT:
   -o, -output string  output file to write found results
   -f, -field string   field to display in output (ip,port,host) (default ip:port)
   -j, -json           write output in JSONL(ines) format
   -l, -limit int      limit the number of results to return (default 100)
   -nc, -no-color      disable colors in output

DEBUG:
   -silent   show only results in output
   -version  show version of the project
   -v        show verbose output

Provider Configuration

The default provider configuration file should be located at $HOME/.config/uncover/provider-config.yaml and has the following contents as an example. In order to run this tool, the API keys / credentials needs to be added in this config file or set as environment variable.

shodan:
  - SHODAN_API_KEY1
  - SHODAN_API_KEY2
censys:
  - CENSYS_API_ID:CENSYS_API_SECRET
fofa:
  - FOFA_EMAIL:FOFA_KEY

When multiple keys/credentials are specified for same provider in the config file, random key will be used for each execution.

Alternatively you can also set the API key as environment variable in your bash profile.

export SHODAN_API_KEY=xxx
export CENSYS_API_ID=xxx
export CENSYS_API_SECRET=xxx
export FOFA_EMAIL=xxx
export FOFA_KEY=xxx

Required keys can be obtained by signing up on Shodan, Censys, Fofa.

uncover supports field flag which can be also used to customize the format of the output, for example in case of uncover -f https://ip:port/version, ip:port will be replaced with results in the output maintaining the defined format.

echo kubernetes | uncover -f https://ip:port/version -silent

Output of uncover can be further piped to other projects in workflow accepting stdin as input.

• uncover -q example -f ip | naabu – Runs naabu for port scanning on the found host.
• uncover -q title:GitLab | httpx – Runs httpx for web server probing the found result.
