Sarenka - OSINT Tool - Data From Services Like Shodan, Censys Etc. In One Place

[sc name=”ad_1″]

SARENKA is an Open Source Intelligence (OSINT) tool which helps you obtaining and understanding Attack Surface.

The main goal is to gathering infromation from search engines for Internet-connected devices (https://censys.io/, https://www.shodan.io/). It scraps data about Common Vulnerabilities and Exposures (CVE), Common Weakness Enumeration (CWE) and also has database where CVEs are mapped to CWE.

It returns data about local machine – local installed softwares (from Windows Registry), local network information (python libraries, popular cmd commads).

For now application has also simple tools like hash calcualtor, shannon entropy calculator and very simple port scanner. More cryptography-math tools and reconnaissance scripts are planned.

Getting started

Description in progress Sarenka is local web application for Windows.

Config

Rirst release gathers data from two search engines. example sarenka/backend/connectors/credentials.json

{   
    "censys": {
        "base_url": "https://censys.io/",
        "API_ID": "<my_user>",
        "Secret": "<my_api_key>",
        "API_URL": "https://censys.io/api/v1"
    },
    "shodan": {
        "base_url": "https://www.shodan.io/",
        "user": "<my_user>",
        "api_key": "<my_api_key>"
    }
}

Features

You can also:

  • calculate hashes based on user string
  • calculate shannon entropy based on user string
  • check is port open|closed (instead always use nmap if you can – it’s slow)

Database

This is tricki part, because we have 863 sqlite3 database files: default, CWE-NONE (some CVE hasn’t cwe_id eg.: CVE-2013-3621) and 861 individual for CWEs

Tech

Description in progress.

SARENKA uses a number of open source projects to work properly on:

And of course SARENKA itself is open source with a public repository on GitHub.

Planned features

  • Rewrite documentation in English (end of 2021)
  • trello/ github instead of Jira
  • Cover 100% code by tests
  • typing backend
  • document all functions and class
  • Docker
  • online demo
  • Jenkins
  • GraphQL
  • Selenium Scrapers
  • More pentesting tools
  • Google Dorks
  • Abstract Algebra calculator
  • Number Theory calculator
  • Server certificate validator
  • tests on Linux
  • NLP
  • d3js visualizations
  • alterntive pure version in command lineS

CI/CD Tools

Tests

  • Tested on Windows 10
  • Tested on Kali Linux kali-rolling 2020.2

Documentation

Till end of March, 2021 documentation will be available only in Polish! The documentation is availabe here.
