Sarenka : OSINT Tool Data From Services Like Shodan, Censys

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

gets data from https://censys.io/ by ip
get data from https://www.shodan.io/ by ip
get DNS data
get WHOIS data
banner grabbing
find CVEs by CWE
generatre pdf report

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)
Suggestions are welcome
- Whant some feature, other tool, library functionality?
- Have any idea or question?
- Don’t hesitate to contact .

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

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