Clearly if her spam caught it, we know that she didn't willingly sign up for it, so the final possibility is they skimmed her email address out of a public leak, and used it at an opportune moment. You can check your email addresses here: https://monitor.firefox.com/ That site will let you know if you've shown up in any public leaks. I've been in 17. Source: over 2 years ago
And Monitor is a good, practical way of finding out if you need to change passwords, plus introduce the topic of password entropy. Source: almost 3 years ago

I already knew about this before I visited HN today, thanks to Firefox Monitor ( https://monitor.firefox.com/ ) :D. - Source: Hacker News / over 3 years ago
I also use Firefox Monitor (which uses the Have I Been Pwned data), but it's limited to 15 email addresses... And I've gone through far more than that. Source: over 3 years ago
You can check it here: https://monitor.firefox.com. Source: over 3 years ago
That is an extremely strange and suspicious link that I would immediately class as a phishing attempt if it had not been posted by an established HN account. The actual link for the title service is https://monitor.firefox.com/. - Source: Hacker News / over 3 years ago
Mozilla also has access to the same databases if you'd prefer using that https://monitor.firefox.com/. Source: over 3 years ago
Yes and no. With your email, they now know 50% of what they need to log into most websites with your info. That other 50% will be easier or harder depending on your password and if you have things like multifactor authentication enabled. They can do a credential stuffing attack where they parse through breached databases for your email and find passwords you've used before. I assume your email is in some leaked...

Remember that hackers pick passwords using dictionaries. Therefore, you cannot use any word as a password. If hackers gain access to the administrative account, they can get to the accounts of other users. Which often happens when the same websites are hacked. We recommend checking your email address for leaks on Have I Been Pwned and Firefox Monitor, for example. Source: over 3 years ago
What probably happened is that some site that she used got hacked and they stored passwords unencrypted. The e-mail address, password combinations are sold for pennies to hackers who try to monetize them. She should change passwords on any other site where she used that password. She can probably find which site leaked the password here or here. Don't engage with the scammers. Source: over 3 years ago
Maybe monitor.firefox.com is for you then. If you set it up you can "clear" old breaches and get automatically notified without actively checking. The dataset is from haveibeenpwned.com, so no difference there. Source: over 3 years ago
