After a spate of high-profile data breaches, including those at social networking sites LinkedIn and MySpace, which have affected hundreds of millions of accounts in total, it's important to know whether you've been hacked. Thankfully, there's a quick, free and easy way to see if you're at risk from a number of recent data breaches.
How to check if your account's been hacked
Go to
https://haveibeenpwned.com/ and enter your email address. Use any address you're concerned may have been hacked – for example, the one you usually log in to LinkedIn with.
It'll tell you if your account's been hacked. You'll be shown a list of breaches you were 'pwned' in, with some background info on the hack, plus what data was compromised – eg, email address, password, date of birth, etc.
If my details aren't on there does that mean I haven't been hacked?
No – the website won't tell you everywhere you may have had data stolen from, so you still need to be vigilant. The site itself acknowledges it only has "a small subset of all the records that have been breached over the years".
