A key part of cybersecurity is password management and protection. But what should you do if your current or past security practices lead to a data breach?
In today’s digital age, receiving a notification that your personal data has been compromised can be an alarming experience. Whether it’s an email from a business, a letter from your bank, or a public announcement of a breach, the feeling of vulnerability is universal. Unfortunately, data breaches have become all too common, affecting institutions ranging from global banks and popular social media platforms to e-commerce stores and even government agencies. The result? Sensitive information such as your address, Social Security Number (SSN), and credit card details can end up in the hands of cybercriminals.
While you may have little control over a company’s security measures, you can take proactive steps to protect yourself and mitigate the potential damage after a breach. This guide outlines the key actions you should take to safeguard your personal and financial information.
Step #1 - Change Your Passwords Immediately
The first and most critical step is to update your passwords. Begin with the account that was breached, then proceed to change passwords for any other accounts where you may have used the same or a similar password.
Why this matters: Many people reuse passwords across multiple accounts, which can lead to a domino effect if one password is exposed. To enhance security:
Use unique passwords for every account.
Opt for a password manager to generate and securely store complex passwords.
Avoid common or easily guessable passwords, like “123456” or “password.”
Step #2 - Enable Multifactor Authentication (MFA)
Multifactor authentication (MFA), also known as two-factor authentication (2FA), provides an extra layer of security. Even if a hacker has your password, they won’t be able to access your account without the second authentication factor.
Common forms of MFA include:
Text messages: A code sent to your phone.
Authentication apps: Apps like Google Authenticator or Authy.
Security keys: Physical devices used to verify your identity.
Enable MFA for all accounts that offer it, starting with the breached account. This simple step can prevent unauthorized access and keep your accounts more secure.
Step #3 - Monitor Your Financial Accounts
If your payment information was exposed, such as credit card or bank details, it’s crucial to stay vigilant. Check your financial accounts frequently for any suspicious or unauthorized transactions.
Steps to take:
Notify your bank or credit card provider about the breach.
Request a new card if necessary.
Set up transaction alerts to be notified of any unusual activity.
Proactively reporting a breach can help you avoid liability for fraudulent charges and enable your financial institution to guide you through additional protective measures.
Step #4 - Freeze Your Credit to Prevent Identity Theft
Breached personal information can be sold on the dark web, allowing criminals to open lines of credit or loans in your name. A credit freeze is an effective way to prevent this.
How to freeze your credit: Contact each of the three major credit reporting agencies to initiate a freeze:
Equifax
Experian
TransUnion
Freezing your credit is free and can be done online. It won’t impact your credit score and can be temporarily lifted if you need to apply for credit.
Step #5 - Review the Breach Notification Carefully
The notification you receive after a data breach provides critical details about the incident. Carefully read through it to understand the potential impact on your information.
Key details to look for:
What type of data was exposed (e.g., passwords, financial information, personal identifiers).
Steps the company is taking to mitigate the breach, such as offering free credit monitoring.
Any specific instructions to secure your account.
Check the company’s website regularly for updates. In many cases, the full scope of the breach may not be immediately known, and further details may emerge later.
Step #6 - Strengthen Your Cybersecurity Defenses
Protect your devices and online activity with robust cybersecurity tools. These tools can help prevent further attacks and secure your sensitive information.
Recommended tools include:
Antivirus/anti-malware software: Protects your devices from harmful programs.
DNS filtering: Blocks malicious websites and phishing attempts.
Email spam filtering: Reduces the risk of falling victim to phishing scams.
Virtual private network (VPN): Masks your online activity, especially on public Wi-Fi networks.
VPNs are easy to use and offer an added layer of security, making them a valuable tool for safeguarding your data.
Step #7 - Stay Alert for Phishing Scams
Data breaches often result in an increase in phishing attempts, as exposed email addresses become targets for scammers. These emails are designed to trick you into providing additional sensitive information or clicking on malicious links.
How to identify phishing scams:
Hover over links to check their destination before clicking.
Visit websites directly instead of clicking on links in emails or text messages.
Be wary of emails from unknown senders.
Stay cautious about phishing attempts on social media and SMS.
When in doubt, verify the email or message through an official source.
Step #8 - Keep Your Software Updated
Unpatched vulnerabilities in software are a common entry point for hackers. Regularly updating your software ensures that security patches are applied, closing these gaps.
What to update:
Device operating systems.
Installed apps and software.
Firmware for routers, printers, and smart devices.
Automating updates can make this process seamless and ensure your devices remain protected.
