Salt Typhoon logged into telecom network gear with stolen credentials in all but one case Talos examined

Cisco Talos's February 2025 analysis of Salt Typhoon's telecom intrusions found the actor used stolen legitimate logins on Cisco devices in all but one case. It then pulled more logins from weakly encrypted router configs and captured TACACS and RADIUS keys, so credentials stored on network gear are the first exposure for defenders to close.

The files surfaced on an anonymous onion site and Check Point words its conclusion conditionally, so the call pattern is usable for training but unverified.
