700Credit Breach: What Organizations Need to Know

Outpost24’s Threat Intelligence team reports that 700Credit suffered a supply-chain style data breach in late October 2025 in which attackers used valid API credentials from a compromised integration partner to exfiltrate millions of consumer records (the company disclosed ~5.6M consumers affected; sellers later claimed ~8.4M records). The advisory describes containment actions, underground forum sales and actor profiling (seller aliases ROOTBOY/avtokz), and highlights API/credential governance and external attack-surface monitoring as key mitigations.
