It can be difficult to tell if someone has hacked your Yahoo Mail account, but there are several warning signs you can look for. You should be especially vigilant if you hear about a widespread data breach where your password or login information may have been exposed. If you suspect that your Yahoo email has been hacked or compromised, it’s important to act quickly to protect your data.

It may not always be obvious that someone has gained access to your email and the information in it, and it is intentional. The longer it takes to re-secure your account, the longer the hacker can use it.

Here are a few things to look out for.

Are you still receiving email? You may notice that fewer messages are landing in your inbox, which could be a sign that someone is getting them before you. It could also be nothing; you may just be having a quiet email day, but if you don’t receive anything for several days, you should probably take a closer look.
