Tis a common question isn’t it. People never really know if their account has been hacked or not. Robert Crane, fellow MVP and SMB IT Professional member, shared this little gem last week with us. This particular site https://pwnedlist.com/ allows you to enter your email address and that’s it. Based on the information that this site has received they will tell you if your email address is in fact on their list of hacked accounts.
How reliable it is, is anyone’s guess. They rely on information that they’ve collected from various sources. They state on their site that they do not actually keep your email address, but they compare it to a “hash” of your address – that way if their site gets hacked, the information will be useless. Provided of course that what they say is correct, there’s no real harm in trying it. You don’t need to give them your password or any other personal information.
Certainly it’s worth giving it a try to see if your account has been hacked.
