According to the revelations made, this breach has its roots going back to late October 2025, when 700Credit noticed some unusual traffic associated with an exposed API. The firm has more than 200 integration partners who are connected to consumers’ data through APIs. It has been found that one of these partners was compromised as early as July 2025, but this notification was not made to 700Credit, thus leaving an opportunity for hackers to gain unlawful access to an API used for fetching consumers’ credit details from this API connected environment.
700Credit called this attack a "sustained velocity attack" that began October 25 and continued for over two weeks before being completely contained. Although the company was able to disable their vulnerable API once aware of the attack, attackers had already harvested a large chunk of customer information by exploiting this security hole. The attack is estimated to have compromised 20 percent of available information that was accessed through this vulnerability.
The compromised information comprises highly sensitive personal information like names, physical addresses, dates of birth, as well as Social Security numbers. Although 700Credit asserted that their primary internal systems as well as login credentials as well as mode of payment are safe from any breach, security experts have indicated that the compromised information is sufficient for identity theft, financial fraud, as well as targeted phishing attacks. Consequently, individuals in the company’s database have been advised to exercise vigilance against any unsolicited messages, especially if they purportedly come from 700Credit or related entities.
The Attorney General, Dana Nessel, issued a consumer alert warning people not to brush off the notifications received when a breach has occurred, but to be proactive about protecting themselves against fraud using the services of freezing their credit or monitoring their profiles for unusual activity due to the large-scale release of sensitive data that has happened previously.
In reaction to the incident, 700Credit has already started notifying affected consumers of the breach as a gesture of goodwill, offering two years of complimentary credit monitoring service, as well as offering complimentary credit reports to affected consumers. The company has also partnered with the National Automobile Dealers Association to assist with breach notification with the Federal Trade Commission for a joint notification on affected dealerships.
Law enforcement agencies have been notified of the breach as part of the continued investigations. This vulnerability highlights the increasing danger of the supply chain vulnerability, especially in companies which have extensive networks in handling personal data of consumers.
