In an unprecedented measure to neutralize a sophisticated cyber espionage campaign, T-Mobile network engineers physically severed high-capacity optical fiber cables to isolate compromised network segments. The incident response aimed to purge threat actors associated with the nation-state hacking group Salt Typhoon.
Security audits revealed that the attackers had established deep persistence inside legacy router management interfaces, bypassing traditional software remediation and credential rotations. Severing the physical links forced traffic onto clean backup routes while engineers completely re-flashed compromised switches.
