Third-party gateway breach gives attacker a path into European bank
Daily Cyber News: Third-party gateway breach gives attacker a path into European bank
A European bank was breached through a third-party gateway where strong authentication hadn’t been properly enforced. The attacker used compromised credentials, scanned thousands of internal systems, ran password-guessing attempts, and accessed operational documentation. The intruder later targeted the bank’s central Windows update infrastructure.
Key context: The incident shows how a vendor-managed gateway can turn valid credentials into a route toward sensitive banking systems.
Additional detail: The larger lesson is that third-party ownership doesn’t reduce first-party exposure.
