Have I Been Pwned at https://haveibeenpwned.com/ is an online tool where users can check to see if their account credentials were exposed in a data breach.

The website, created by Troy Hunt in 2013, contains a database of information for over 11 billion breached accounts and enables users to search using their email address, phone number, or password. If an account has been compromised, the website provides victims with details related to the breach, including the impacted website or service, the incident date, and the type of information accessed.

How It Works

With its secure method of searching and extensive database, Have I Been Pwned is a reliable and effective way for users to take control of their account security. The site collects information from public data breaches and stores the details in a searchable database. It then uses k-anonymity to protect user privacy when visitors submit a search. Instead of storing or transmitting the sensitive search information, Have I Been Pwned converts it into a hash. The database then looks for matching hashes and returns the results to the website. This technique ensures that the user’s information is never exposed to the website or anyone who might intercept the network traffic.

Visit Have I Been Pwned and simply type in your email address, phone number, or password to get started.

Further Recommendations

Here are some additional security tips to help you secure your accounts and personal information:

  • Use strong and unique passwords for each online account. Avoid using the same password for multiple accounts, as it can increase the risk of a data breach.
  • Enable multi-factor authentication (MFA) for your online accounts. MFA adds an extra layer of security by requiring you to provide additional verification besides your password.
  • Be cautious when clicking on links or downloading attachments in emails from unknown sources. These links or attachments may contain malware that can compromise your computer or steal your personal information.
  • Keep your software and operating system updated with the latest security patches. Hackers often exploit vulnerabilities in outdated software and operating systems.
  • Use reputable antivirus and firewall software on your computer to protect against malware and other online threats.
  • Regularly monitor your financial accounts for any suspicious activity. If you notice any unauthorized transactions, report them to your bank or credit card company immediately.
  • Limit the personal information you share online. Avoid sharing sensitive information on social media or other online platforms, such as your date of birth, home address, or social security number.

Troy Hunt’s Solution: Rate Limiting Malicious Actors

Troy Hunt found a single solution for his multiple requirements in Cloudflare’s Rate Limiting service. Rate Limiting helps Hunt manage traffic spikes by allowing him to set a limit on the number of requests from individual IP addresses that respectively hit his websites and API over a given period of time. Rate limiting prevents spikes in traffic from reducing performance because each unique user is limited to a certain number of requests.
