700Credit data breach exposes SSNs of 5.8 million consumers

Data breaches linked to financial services companies are no longer rare, but they are even more impactful when Social Security numbers are involved. In the latest incident, US fintech company 700Credit confirmed that the personal data of more than 5.8 million people was exposed. The breach did not originate from a direct compromise of 700Credit’s internal network, which makes it more concerning. It started with a third-party integration partner and grew quietly for several months before it was detected. By the time the issue was fixed, the hackers had managed to steal a significant amount of sensitive consumer data.

DATA BREACH EXPOSES THE INFORMATION OF 400,000 BANK CUSTOMERS

What went wrong at 700Credit?

The company says the breach dates back to July, when a threat actor compromised one of its third-party integration partners, Bleeping Computer reported. During that intrusion, the attacker discovered an exposed API that could be used to access customer information linked to 700Credit dealership customers. The integration partner did not inform 700Credit of the compromise, allowing the access to go undetected.

The suspicious activity was not detected until October 25, when 700Credit detected unusual behavior on its systems and launched an internal investigation. The company says it hired third-party computer forensic specialists to assess the scope of the incident and determine what data had been affected.

According to the company’s findings, certain records within its web application were copied without authorization. These records relate to car dealership customers using 700Credit services. CEO Ken Hill later confirmed that approximately 20% of consumer data accessible through the affected system was stolen between May and October.

What data was exposed and why it is important

While 700Credit has not released an exhaustive list of all the data fields involved, the company has confirmed that highly sensitive personal information was exposed. This includes Social Security numbers, which significantly increases the risk of identity theft and financial fraud. When SSNs are compromised, the impact is long-term. You can’t just change them like a password.

The company has posted a dedicated page on its website describing the breach and the types of information affected. As part of its response, 700Credit is offering affected individuals 12 months of free identity protection and credit monitoring through TransUnion. You have 90 days to enroll in this service after receiving notification.

Notably, audio streaming platform SoundCloud and adult video sharing platform Pornhub also suffered data breaches linked to third-party providers. There is no indication that the same vendor was involved in all three incidents, but the cases highlight how risky third-party access can be when vendors handle sensitive consumer data.

CyberGuy contacted 700Credit for comment but did not receive a response before publication.

PASSWORD MANAGER FINED AFTER MAJOR DATA BREACH

Six steps you can take to stay safe after a data breach

When violations like this occur, the damage is not always immediate. Your data can remain in underground markets for months before it is abused. That’s why it helps to close things early. Here are six practical steps you can take.

1) Use powerful antivirus software

A good antivirus helps block malicious downloads, phishing links, and spyware that often follow large data leaks. Attackers know that your data is exposed and may try to attack you directly with malware-based scams.

The best way to protect yourself from malicious links that install malware and potentially access your private information is to have powerful antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

Get my picks for the best antivirus protection winners of 2025 for your Windows, Mac, Android, and iOS devices at Cyberguy.com.

2) Switch to a password manager

If you’re still reusing passwords, now is the time to stop. A password manager helps you generate strong, unique passwords for each service and keeps them stored securely. If one site is breached, the rest of your accounts remain protected.

Next, check to see if your email has been exposed in previous breaches. Our number one password manager (see Cyberguy.com) includes a built-in breach scanner that checks to see if your email address or passwords have appeared in known breaches. If you discover a match, immediately change any reused passwords and protect those accounts with new, unique credentials.

3) Enable two-factor authentication everywhere

Light 2FA for email, banking, social media and cloud accounts. Even if someone has your password, they can’t log in without the second factor. App-based authenticators are more secure than SMS, whenever possible.

4) Sign up for identity theft and credit monitoring

Monitoring services alert you when new accounts, loans, or credit checks appear in your name. Early warnings give you the opportunity to act before serious financial damage occurs.

Identity theft companies can monitor personal information such as your Social Security number, phone number, and email address, and alert you if it is sold on the dark web or used to open an account. They can also help you freeze your bank and credit card accounts to prevent further unauthorized use by criminals.

5) Consider a personal data deletion service

Your phone number, address and other details are often already scattered across data broker sites. Data erasure services help reduce your digital footprint, making it harder for attackers to identify and target you after a breach.

While no service can guarantee complete removal of your data from the Internet, a data deletion service is truly a smart choice. They are not cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically deleting your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to delete your personal data from the Internet. By limiting the information available, you reduce the risk of scammers cross-referencing leak data with information they can find on the dark web, making it harder for them to target you.

6) Freeze your credit if your social security numbers are exposed

If your Social Security number is involved, a credit freeze is one of the strongest defenses. Prevents new credit accounts from being opened without your approval and can be temporarily canceled when necessary.

Kurt’s Key Takeaway

Third-party APIs and integrations are essential for modern digital services, but they also expand the attack surface. When outside partners do not quickly disclose violations, the subsequent impact can be enormous, as this case demonstrates. If you receive a notification from 700Credit, take it seriously. Sign up for credit monitoring service, review your credit reports, and consider blocking them. Even if no fraud has occurred yet, breaches involving Social Security numbers often result in the abuse being delayed months or even years later.
