Affected Telecom Giants Struggle to Evict Hackers

In a call with reporters, the Cybersecurity and Infrastructure Security Agency (CISA) disclosed that the affected telecom giants are still grappling with the issue. The primary challenge lies in determining the hackers’ intentions, making it difficult for the companies to effectively counter their presence.

Background on Salt Typhoon’s Initial Infiltration

In October, news broke about Salt Typhoon’s alleged deep infiltration of networks belonging to AT&T, Verizon, and Lumen (formerly CenturyLink), among others. T-Mobile, while targeted, successfully rebuffed the attackers. The unauthorized access granted by Salt Typhoon enabled Chinese hackers to intercept real-time unencrypted calls and text messages, as well as metadata about the communications’ senders and recipients.

U.S. Officials Suspect Widespread Espionage

The U.S. government believes that the industry-wide hacks may be part of a large-scale espionage operation by China. The hackers were found to be targeting not only ordinary Americans but also U.S. officials, presidential candidates, and even systems housing U.S. government requests related to Chinese individuals under surveillance.

CISA and FBI Urge Encryption Adoption

During the call with reporters, CISA and FBI officials stressed the importance of using encrypted messaging apps to prevent communications from being intercepted by hackers or spies. One official noted that encryption is a powerful tool, emphasizing, "Encryption is your friend; whether it’s on text messaging or if you have the capacity to use encrypted voice communication."

Examples of Secure Messaging Apps

Several popular end-to-end encrypted messaging apps offer protection against interception. Signal and WhatsApp are two widely used examples, which ensure that neither the app makers nor any third-party entities can access users’ communications.

U.S. Government Guidance for Telecom Networks

The U.S. government has provided guidance to telecom networks on hardening their systems against Salt Typhoon’s attacks. Each affected company will need to tailor its remediation efforts, making every case unique.

The ongoing presence of Salt Typhoon within major U.S. telecom networks highlights the complexities and challenges involved in countering sophisticated cyber threats. The hacking group’s intent remains unclear, adding to the difficulty for telecom giants in effectively removing them from their networks.

Impact on National Security

The U.S. government’s struggle against China-backed hackers raises concerns about national security. The affected telecom networks’ inability to evict Salt Typhoon underscores the gravity of the situation and the need for strengthened cybersecurity measures across the board.

U.S. Government Officials React to Ongoing Hacking Campaign

CISA and FBI officials have urged Americans to adopt secure communication practices, such as using encrypted messaging apps, to prevent their communications from being intercepted by hackers or spies.

Encryption is Your Friend

In light of the ongoing hacking campaign, CISA and FBI officials emphasized the importance of encryption in protecting against interceptions. They encouraged users to take advantage of end-to-end encrypted messaging apps, such as Signal and WhatsApp, which offer robust protection against interception.

What Is End-to-End Encryption?

End-to-end encryption ensures that only the sender and receiver can access the contents of a message. This level of security prevents any third-party entities, including app makers or hackers, from accessing sensitive information.
