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 (, 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.


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

"censys": {
"base_url": "",
"API_ID": "<my_user>",
"Secret": "<my_api_key>",
"API_URL": ""
"shodan": {
"base_url": "",
"user": "<my_user>",
"api_key": "<my_api_key>"


  • gets data from by ip
  • get data from 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)


    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


    Description in progress.

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

    • Renderforest – logo generator
    • gawk – python migrate –database CWE_ID
    • chocolatey
    • PyCharm – Community Edition
    • Technology – description
