Identifying legitimate emails from the iTunes Store

Pretty much everybody’s Yahoo account is on the “dark web”, as there’ve breached a couple of times over there.

Your gmail is probably also on the “dark web”, if you’ve used that with any of the gazillion services that have themselves gotten breached.

By all means switch your email, but your bank isn’t really telling you anything useful here. Or anything actionable.

What they may be intending to tell you is to avoid re-using any passwords, as those too are widely available on the “dark web”.

It’s quite common to brute-force the password hashes—some of the servers unfortunately even stored users’ passwords in cleartext, which is even easier for the attackers—and the attackers then try stuffing those credentials into every other service known, as well as sending you ominously-worded “we know what you did” and “sextortion” messages and “we have access to your computer” almost always involving the “Here’s your password!” to scare you into doing something unwise..

Put differently, don’t trust any email even that which appears ro be from a trusted sender, and never re-use passwords, etc...

If you’d like to see how many breaches you’ve been caught up in... haveibeenpwned. Most of us have been caught up in multiple breaches, if we’ve been at all active on the ‘net for a while. Some of which you might not have heard about, too.

BTW: “dark web” is a reference to the “evil” part of the internet, which arguably comprises the entirety of the internet.
