Knowing how to tell if your data has been compromised is critical to safeguarding your identity, finances, and other personal information.
This guide will provide a step-by-step overview of identifying data leaks and what to do if your data has been breached. We will also provide tips and resources to help you protect your data in the future. By the end of this guide, you will have the knowledge and resources needed to ensure your data remains safe and secure.
What is a data breach or leak?
A data breach or data leak refers to the unauthorized acquisition or disclosure of data. It can happen through a variety of means, such as cyberattacks, lost or stolen devices, or improperly disposed paper copies of sensitive information.
Data breaches affect businesses and individuals and can result in various harmful outcomes, including identity theft, fraudulent financial activity, loss of data confidentiality, and reputational harm.
A data breach may occur when a company’s servers or other computer systems are hacked when someone improperly accesses device or network logs, or through human error, such as an employee leaving a laptop in an airport or a USB drive in a public place. Some data breaches are accidental, but others are done maliciously.
Data breaches are often done to steal information, like credit card numbers, usernames, passwords, and financial information.
How to tell if your data has been compromised
If you’re concerned that your data has been breached, the first step is to determine where the breach occurred. Once you know the source of the breach, you can then follow the instructions provided by the service provider to determine if your data has been compromised.
We’ve outlined a few common scenarios below. Be sure to follow the instructions provided by the service provider to determine if your data has been breached.
- Mail or Email – If you use email or a mailing address as your username, or if someone has access to your inbox or email account, they could use that information to access your account. Also, if your email provider has been breached and your email address and password are used on any other sites, your data might be in jeopardy.
- Passwords – If you use the same password for all your online accounts, a data breach at one company could put your personal data at risk. Make sure you change your passwords regularly, use a password manager to create random passwords for each account, and avoid using personal information like your name, birthdate, or Social Security number as your password.
- Third-Party Services – Many online services, such as email providers, cloud storage services, social networking sites, and financial institutions, use third-party vendors to store your data. If one of those third parties is breached, your data could be at risk.
What to do if your data has been breached
If there is a good chance that your data has been breached, you should take steps to ensure that your information is properly protected. If you are sure that your data has been compromised, you should take immediate action to mitigate the damage and prevent further harm to your accounts. Some steps you can take to protect your data include:
- Keep Track of Your Data – The first step in protecting your data is to understand what information you have. This includes everything from your name, address, phone number, and credit card information to your online logins and passwords. If you know what data you have, you can better protect it.
- Monitor Your Accounts – It’s important to regularly monitor your online accounts to identify any suspicious activity. This includes your email accounts, social media accounts, and online banking and financial accounts. If you notice that someone has logged into your account or any changes have been made, report it to the company immediately.
- Sign up for Data Breach Alerts – If you’re concerned that your information has been breached, sign up for data breach alerts from the three major credit bureaus: Equifax, Experian, and TransUnion. They will let you know if your information is at risk.
Tips for protecting your data
Now that you know how to tell if your data has been compromised and what to do if it has, let’s take a look at some ways to protect your data in the first place. To protect your data, you should:
- Use Strong Passwords – Using easy-to-remember passwords is tempting but a huge security risk. Instead, use a password manager to create strong, unique passwords for each account and update them every six months.
- Use Two-Factor Authentication – Add an extra layer of security to your online accounts by using two-factor authentication. This means that when you log in to your account from a new device, you’ll need both your password and a unique code generated by an app or sent to your phone via text message.
- Regularly Monitor Your Finances – By monitoring your finances regularly, you can identify fraudulent activity before it has a chance to harm you. You can do this by logging into your account at least once per month and paying attention to your spending habits.
Resources to help you protect your data
Passwords – Password management solutions are a great way to keep track of all of your passwords, while also ensuring they are strong and unique. We recommend using a password manager like LastPass or 1Password to protect your data.
Two-Factor Authentication – We recommend setting up two-factor authentication on any account supporting it. Here are the two most popular options:
- Google Authenticator – This is a free app that works with a wide variety of services and can generate one-time use codes.
- Duo – This is another free service that works with a wide variety of services and can generate one-time use codes.
Mail or Email – If you use email or a mailing address as your username, or if someone has access to your inbox or email account, you can change your account login information to protect your account. If you use your email address or mailing address as your username, log in to your account and change the username to something unique. You can also add two-factor authentication to your account to add an extra layer of security.
Data breaches and data leaks are unfortunately common occurrences in the modern digital landscape. Fortunately, they can be identified, monitored, and mitigated to minimize harm to your personal information. One of the best ways to protect your data is to use strong passwords and to use two-factor authentication on any account that supports it.
