A new free website lets you quickly discover if your accounts have been compromised by cyber-security breaches.

Have I Been Pwned? includes information related to 66 data breaches, including Ashley Madison, Adobe, Vtech, Tesco and Snapchat.

Enter your email address or user name and click ‘pwned?’ to discover if your accounts have been breached or pasted. A ‘paste’ is when a website is compromised and samples of data are dumped online by the hackers.

We searched three personal email addresses and the third – one we don’t use – was found to have been compromised by the Adobe hack.

Have I been pwned

Have I Been Pwned? was set up by security expert Troy Hunt, who wanted to create a simple website anyone could access if they were worried about being put at risk by an online breach.

“Data breaches are rampant and many people don't appreciate the scale or frequency with which they occur,” he explained.

“By aggregating the data here I hope that it not only helps victims learn of compromises of their accounts, but also highlights the severity of the risks of online attacks on today's internet.”

Have I Been Pwned? is free to use – Hunt is funding the website himself, but users can donate.

Even if you haven’t been affected by any of the security breaches you can sign up to be informed if your account is compromised in the future.

To stay safe, make sure you regularly change and pick a secure password and check your security software is up-to-date. Take a look at our guide: Seven easy tips to protect your PC from hackers and malware.
