Data breaches continue to affect major organizations, and recent reporting has linked the ShinyHunters extortion group to incidents involving Charter Communications, a company with services branded as Spectrum. A simple way to check whether your email address appears in a known breach data is to use Have I Been Pwned at haveibeenpwned.com. This site lets you search your email address to see whether it has been found in publicly known breaches. While no public tool captures every incident immediately, Have I Been Pwned is one of the most widely used resources for checking breach exposure and signing up for future notifications. 

If your email address appears in a breach, take the following actions right away:

1. Change the password on the affected account.
2. Change your password everywhere you reused that password.
   It’s essential to change reused passwords, because exposed credentials are often reused in follow-on attacks.
3. Use a new, unique password for every account.
4. Enable multi-factor authentication wherever possible.
5. Be especially cautious of phishing emails or texts that reference recent breach news or ask you to log in urgently.
