Introduction

Holla folks! Today’s episode of TuesdayTool delivers a tool I recently discovered that can be used to gather open source intelligence related to email addresses or mobile phone numbers. This tool will crawl all sites that have registered the submitted data; say email address or phone number and return with a consolidated result of all the sites. The name of the tool is ‘Epieos’. Epieos crowned itself as the ultimate OSINT Tool. This guide will explain how to use ‘Epieos’ straightforwardly, making it accessible even for those without a technical background.

What is the ‘Epieos’ Tool?

Epieos specializes in gathering data related to email addresses and phone numbers. It can reveal associated accounts, check for data breaches, and provide insights into using an email address or phone number across different platforms. Epieos offers a paid version with additional features, but the free version is still quite powerful for basic investigations.

How to Use Epieos

Epieos is simple to use and can be broken down into a few easy steps:

  1. Access the Epieos Website: Visit the Epieos website to start your investigation.
  2. Input an Email Address or a Phone Number: You will see a search bar where you can enter the email address you want to investigate. Make sure to double-check the spelling for accurate results.
  3. Input a Phone Number: You can also search for a phone number by inserting the phone number plus the country code you want to investigate. Make sure you select the phone number icon before typing the phone number.
  4. Review the Report: After entering the email address, or the phone number, click on the search button. Epieos will generate a report that includes:
  • Associated Accounts: It will list other accounts linked to that email address or phone number, which may include social media profiles or other online services.
  • Data Breach Information: If the email or phone number has been involved in any data breaches, Epieos will provide details about these incidents.
  • Additional Insights: The tool may also reveal links to Google Calendar or other relevant data connected to the email or phone number.

5. Analyze the Findings: Take time to review the information provided in the report. This can help you understand the online presence associated with the email address or phone number and identify any potential security risks.

Practical Applications of Epieos:

Epieos can be particularly useful in various scenarios:

  • Verifying Suspicious Emails: If you receive an unexpected email from an unknown sender, you can use Epieos to check if it’s linked to any known accounts or breaches.
  • Verifying Phone Number: If you receive a suspected SMS, or WhatsApp message from an unknown sender, you can check it using Epieos
  • Identifying Data Breaches: Knowing whether your email has been compromised can help you take necessary actions, such as changing passwords or enhancing security measures.
  • Connecting Accounts: If you’re trying to understand someone’s online presence or gather information for research purposes, Epieos can help map out their associated accounts.

Important Considerations

While Epieos is a powerful tool, it’s essential to use it responsibly:

  • Privacy Awareness: Be mindful of privacy concerns when investigating others’ information. Always consider ethical implications.
  • Data Accuracy: The information provided by Epieos is sourced from public data; therefore, it may not always be complete or up-to-date.

Conclusion

In summary, Epieos serves as a valuable resource for anyone looking to conduct basic investigations into email addresses and phone numbers without needing extensive technical knowledge. By following these steps and using them thoughtfully, users can harness the power of open-source intelligence (OSINT) effectively.
