According to cybersecurity experts featured by CNBC, the biggest error individuals or organizations make following a data breach is pretending it didn't happen. Actively avoiding the issue or delaying responses only amplifies risk and leaves affected data exposed to further misuse.
Here are some things you should do instead:
1) Understand exactly what was exposed, how it happened, and who might be affected. Acknowledge the breach immediately, denial only delays recovery.
2) Immediately change passwords on breach accounts and any other using the same or similar credentials. Use strong, unique passwords or a password manager for better protection.
3) Add a second layer of security wherever possible, SMS codes, authenticator apps, or hardware keys. These are all to stop unauthorized access even if a password is compromised.
4) Watch for unusual charges or credit inquiries. If financial data was exposed, consider placing a fraud alert or freezing your credit with major bureaus to prevent new accounts from being opened in your name.
5) Phishers and scammers often exploit breach news. Be skeptical of unsolicited emails, texts, or call claiming to help with the breach.
6) Depending on your location or industry, there may be legal processes for disclosing a breach, especially for businesses. Consult counsel or breach notification guidelines as needed.
Simply hoping a breach goes away is the worst response. Facing reality, swiftly and strategically is your most powerful tool. Change passwords, strengthen your security, monitor for misuse, and stay informed. Acting early means reclaiming control.
