The Byzfunder Data Breach
Byzfunder 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 Byzfunder 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
I received a notice that my information may have been involved in a data breach. What should I do?
Take the notification seriously and read it carefully. It should outline what specific information was affected (e.g., name, Social Security number, legal case data). Even if you believe your risk is minimal, it’s best to take proactive steps to protect yourself. Some of these recommended steps can be found listed below.
What immediate actions should I take?
- Monitor your financial accounts – Regularly check your bank, credit card, and online accounts for unauthorized transactions.
- 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.
- Set up two-factor authentication (2FA) – Enable 2FA on your email, banking, and other sensitive accounts to add an extra layer of protection.
- 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.
What is credit monitoring, and how should I use it?
Credit monitoring tracks your credit report for changes or suspicious activity. If the organization that was breached offers this service for free, it’s highly recommended you enroll. These services can alert you quickly to potential fraud and help prevent further damages.
How long do I need to stay vigilant?
The effects of a data breach can surface months or even years later. Stay alert to signs of identity theft for at least 12–24 months. Keep an eye on your credit reports, mail, and any unfamiliar account activity.
Who can I contact if I need help?
Use the contact details provided in the breach notification. You can also report identity theft to the Federal Trade Commission at www.identitytheft.gov for recovery resources.
