Have you ever received a notification about a data breach and thought ‘Was my information actually stolen?’ According to IBM’s 2025 Cost of a Data Breach Report, the average global data breach in 2025 costs around $4.44 million.
However, one of the problems with news about breaches is that they generate more questions than answers. Was your email compromised? What about your password or phone number?
Rather than just speculating, you can take action and find answers to your questions. This article will help you understand how to confirm the breach, check if your data has been leaked, and how to protect it.
First, Verify the Breach
Once you hear a company has experienced a data breach, your gut reaction is probably to check your email, and that’s fine. However, be cautious about what you click on.
Criminals understand that people become stressed during data breaches. Sometimes, they send fraudulent emails pretending to be a legitimate business. These emails may instruct recipients to click on a link to either ‘secure their account’ or supply their password, credit card, or bank information.
Instead, you should go directly to the company’s website or its app. Look for a notice that deals with security, support, or privacy matters.
If you received an email, compare the two messages to learn what the company has added to its web page. A legitimate data breach notification should inform you about what happened and, more importantly, what information has been compromised.
Understand What Information Has Been Compromised
Remember that not all data breach incidents are the same. For example, while it’s worrisome for hackers to acquire your email address, it’s different if they have your password, bank information, or ID details.
Read the breach report that the company has sent you thoroughly, taking notes of what information has been compromised. Such information may include your name, email, phone number, password, payment information, and more.
This is important as it will help you know what steps should be taken next. If your email is the only piece of information that was compromised, you will have to be on the alert for phishing scams.
If your password has been affected you will need to change it immediately. If you have had your financial information or identity documents compromised, you will need to take more serious actions to mitigate the consequences.
Find Out if Your Information Is Part of Any Breach
The technology in breach monitoring services can help you identify whether your phone number or email address has been included in any previous data breaches. For a more complete picture of things, you may also use other methods.
One of such methods is the use of a digital footprint checker to identify what personal information associated with you is already up on the internet. With the help of this checker, you can discover old profiles, previously posted email addresses, and usernames.
In case you find an email belonging to a breach, do not panic. Finding out your email has been on the breach list does not mean it is being used illegally. It is useful to remember that no breach checking service offers complete assurance that your personal data has never been leaked. Some breaches pass unnoticed.
Investigate Suspicious Activity on Your Accounts
Sometimes, it’s not necessary to check a breach database to identify an issue. Your accounts could be giving you clues already. Take a look at your email, social media, online shopping, cloud storage, and other essential services to check if you notice any unusual activity. Look out for the following,
● A password reset request you didn’t initiate
● A login from a strange device
● Having your recovery email changed or messages you never sent
Be careful with your email. If someone gets access to it, they will most likely be able to reset passwords for many other linked accounts. If you notice something suspicious, do not wait to see what will happen next. Change your password, log out of all other sessions, check your security settings, and remove anything that you do not recognize.
Change Your Passwords, and Do Not Recycle Them
In the event your password has been compromised, you should change it without delay. However, do not change it only a bit, to a very similar password.
Reusing passwords is extremely dangerous after a security incident. If you use the same password across your email, Instagram, shopping account, and other services, then once you lose access to any one account, you might expose all the other accounts.
The first step is to focus on e-mails and financial transactions. From there, check all other important accounts and make sure each of them has a unique password. A password manager is a great way to store many account passwords.
What to Do After You Confirm a Breach
There is no need to feel overwhelmed after realizing your data has been compromised. Focus on the most crucial accounts first, such as email and banking. Change compromised or reused passwords and replace them with strong ones.
After that, continue keeping an eye on your accounts and stay cautious about unsolicited calls, emails, and messages. It can be a shocking experience to learn that your private data is no longer private, but it shouldn’t make you feel helpless. The best thing you can do after being aware of the breach is to act quickly.
