It’s a sinking feeling: you receive an email from an organisation informing you of a data breach. In today’s digital world, these incidents are alarmingly common. IBM reports that in 2023, 82% of data breaches involved cloud storage, highlighting the vulnerability of information entrusted to online platforms. Whether it’s a bank, a social media giant like Facebook, or even a government agency, cybercriminals are constantly searching for weaknesses to exploit. This can leave your personal information, such as your address, tax file number, and credit card details, exposed.
While you can’t prevent a data breach from happening, you can take control by responding quickly and decisively. Below is a list that outlines crucial steps to mitigate the damage and protect yourself:
-
Change Your Passwords Immediately
Your first priority is to change your passwords. Start with the password for the compromised service, then change any other accounts using the same password. This highlights the importance of unique passwords for every online platform. Using a password manager can help you generate strong, unique passwords and keep track of them securely.
-
Activate Multifactor Authentication (MFA)
MFA adds an extra layer of security to your accounts. Enable MFA wherever possible, prioritising the breached service and your most sensitive accounts. Common MFA methods include text messages, authentication apps, and security keys.
-
Scrutinise Your Bank Accounts
If the breach involved payment card details, monitor your bank accounts closely for any suspicious activity. Report the breach to your bank and request a new card if necessary. Proactive communication with your bank can help protect you from fraudulent charges and ensure you’re not held liable for any unauthorised transactions.
-
Contact Credit Reporting Agencies
Cybercriminals often sell stolen data, which can be used to commit identity theft. Contact your bank or relevant governing body to find out what steps you need to take to secure your data. This can prevent criminals from opening new accounts or taking credit out in your name.
-
Thoroughly Examine the Breach Notification
Carefully review the data breach notification from the organisation. Check their website for updates and seek clarification on the following:
- The type of data exposed: Was it passwords, credit card numbers, or other sensitive information?
- Remedial actions: Is the organisation offering credit monitoring or other services to assist affected individuals?
- Account security instructions: Are there specific steps you need to take to secure your account?
Continue to monitor the organisation’s website for updates, as the full extent of a breach may not be immediately apparent.
-
Strengthen Your Cybersecurity Defences
Enhance your device and network security with these essential tools:
- Antivirus/anti-malware software: Install reputable security software to protect against malware and viruses.
- DNS filtering: Block access to malicious websites that may attempt to steal your data.
- Email spam filtering: Prevent phishing emails from reaching your inbox.
- Avoid using public Wi-Fi: It is better to hot spot your phone in public rather than using publicly available Wi-Fi.
-
Stay Vigilant Against Phishing Scams
Data breaches often expose email addresses, making you a target for phishing attacks. Cybercriminals use sophisticated techniques to impersonate legitimate organisations and trick you into revealing personal information. Be wary of unexpected emails and follow these precautions:
- Hover over links: Before clicking, check if the link destination matches the displayed text.
- Access websites directly: Type the website address into your browser instead of clicking on links in emails or text messages.
- Be cautious of unknown senders: Exercise caution when interacting with emails from unfamiliar individuals or organisations.
- Watch for phishing attempts on social media and text messages: Phishing attacks can occur on various platforms.
- Verify information through official sources: If in doubt, contact the organisation directly through their official website or phone number.
- Implement an email security product: Email security products will discover and quarantine suspicious emails before they reach your inbox.
-
Keep Software and Systems Updated
Outdated software can contain vulnerabilities that hackers exploit. Ensure your operating system, apps, software, and firmware for all devices (including routers, printers, and smart devices) are updated regularly. Consider automating updates to maintain optimal protection.
Consider implementing a vulnerability scanning service to provide additional peace of mind over the current status of vulnerabilities within your ICT estate.
