T-Mobile targeted in Chinese cyber-espionage campaign

Chinese hackers target US telecom networks.

T-Mobile‘s network was among those breached in a prolonged cyber-espionage campaign attributed to Chinese intelligence-linked hackers, according to a Wall Street Journal report. The attackers allegedly targeted multiple US and international telecom companies to monitor cellphone communications of high-value intelligence targets. T-Mobile confirmed it was aware of the industry-wide attack but stated there was no significant impact on its systems or evidence of customer data being compromised.

The Federal Bureau of Investigation (FBI) and the US Cybersecurity and Infrastructure Security Agency (CISA) recently disclosed that China-linked hackers intercepted surveillance data intended for American law enforcement by infiltrating telecom networks. Earlier reports revealed breaches into US broadband providers, including Verizon, AT&T, and Lumen Technologies, where hackers accessed systems used for court-authorised wiretapping.

China has consistently denied allegations of engaging in cyber espionage, rejecting claims by the US and its allies that it orchestrates such operations. The latest revelations highlight persistent vulnerabilities in critical communication networks targeted by state-backed hackers.
