If Your Email Is On This List, You Must Change Your Password
A mass data leak of email addresses and passwords has affected 771 million people after being published online.
A "spambot" known as Onliner has collected personal data and dumped it on an online server. The server is believed to have originated in the Netherlands.
The scam is said to hack into your emails to access personal information such as banking details, infect your computer with various viruses and send out an enormous amount of spam from your account.
Luckily, a website known as HaveIBeenPwned exists, and offers people around the world a way of finding out if YOU have been hacked.
Owner of the site, Troy Hunt, has named this "the largest single set of data I've ever loaded into HIBP."
Mr Hunt admitted that the hacking scandal was so bad, that he even found himself caught up in it, with his personal email address being found on the list.
And to put into perspective just how many other people would be affected by this too, Mr Hunt added, "Just for a sense of scale, that's almost one address for every single man, woman and child in all of Europe."
The first sign that you have been affected by the "spambot" is that you will receive a barrage of spam emails in your inbox.
However, if you're still not sure, you can check if your email address has been published by searching for it on this website.
The server information has been handed over to Dutch police so that they can work towards shutting it down.
