The website "Have I Been Pwned", or HIBP, was created by Microsoft Regional Director Troy Hunt as a free resource for the public to check if their personal data had been compromised by a breach on the internet. You can visit HaveIBeenPwned.com and enter your email address or account password to see if either had been involved in a data breach. The way Troy has built the site ensures visitors can enter their passwords safely and securely.
Claire had a Yahoo email account and forgot to reset her recovery phone number, so she's now locked out of her account. Leo says that she can try and log into the general Yahoo.com. If that works, then she should be able to go into her account and change the phone number.
Al recently upgraded to Windows 10 and Chrome has been giving him error messages preventing him to go to certain sites. Leo says to trust that. It's likely that the site has some malware code in it that will cause issues down the line. It could be a generic warning though. To be safe, Al shouldn't click on any links. Instead he should hover over it to see what the actual link is. It's possible to spoof a link with HTML code. In fact, Leo suggests turning off HTML in his email client. Leo suggests also using Thunderbird. It will give him the option of text only.
Joe got an email from himself today and he checked his Gmail sent box and it was there. Leo says that's an indication that someone actually got into his account. Leo recommends changing the password immediately and enabling 2nd factor authentication. There's also a link at the bottom of his Gmail account that will tell him where his account is being accessed. He should check that as well. He can also go to Google.com/Dashboard and see what programs he's given access to. Then he can disable any program he doesn't recognize.
Robin is getting those emails that seem to be bounced from her own Yahoo email account. Leo says that's likely a "spoofed" return email address, but it's always wise to change the password just in case. She should use a password vault so it can generate long passwords which can't as easily be hacked. But Leo also says there's something fundamentally wrong with Yahoo's email security and Leo advises getting off it. Go with Gmail instead.
