The Thayer Hotel Data Breach

The Thayer Hotel recently provided notice of the data breach. All of the information stolen is likely valuable and dangerous to affected victims. As is likely to be the case with the Thayer Hotel data breach, in previous cyberattacks, victims of data theft have noticed identity theft attempts ranging from fraudulent charges on bank accounts or credit cards, to unauthorized credit card applications, to medical services or government services ordered in their name, to their information being posted on the dark web, to a massive uptick in the number of spam text messages, calls and emails received.

Data Breach FAQ

1. Monitor your financial accounts – Regularly check your bank, credit card, and online accounts for unauthorized transactions.
2. Change your passwords – Update passwords for any accounts that may be connected to the breach. Avoid reusing old or similar passwords. Use a password manager if needed.
3. Set up two-factor authentication (2FA) – Enable 2FA on your email, banking, and other sensitive accounts to add an extra layer of protection.
4. Place a fraud alert or credit freeze – Contact one of the three major credit bureaus (Equifax, Experian, TransUnion) to place a fraud alert or freeze your credit report. This makes it harder for someone to open new accounts in your name.
