Millions of customers of large businesses have been left vulnerable to identity theft, thanks to a security flaw that exposes their personal data to illicit download. Among those affected are clients of Europcar, a vehicle rental service, and FxPro, a trading platform.

Service providers using Onfido, an identification verification (IDV) service, let a major flaw in their security go unchecked, in the form of an exposed admin token that potentially left app users’ biometric data exposed.

Using this safety gap, threat actors could have downloaded personally identifiable information (PII), including copies of client-submitted IDs, passports, and driver's licenses.
On December 19, Mikail Tunç, a security researcher, discovered a front-end application programming interface (API) token in several mobile apps used by millions of customers worldwide.
