T-Mobile’s Network Breached as Part of Chinese Hacking Operation

Mobile U.S. Inc.’s network was among those recently breached by Chinese hackers in an attack on multiple telecommunications companies.

“T-Mobile is closely monitoring this industry-wide attack,” a company spokesperson said Saturday in an emailed statement. “We have not seen significant impacts to T-Mobile systems or data, and have no evidence of impacts to or exfiltration of any customer information others may have experienced. We will continue to monitor this closely, working with industry peers and the relevant authorities.”

The Wall Street Journal reported earlier that Bellevue, Washington-based T-Mobile’s systems were among those hacked.

U.S. officials said this week that Chinese state-sponsored hackers perpetrated a “broad and significant cyber-espionage campaign” in which they breached multiple telcos. The hackers infiltrated the networks in an attempt to steal customer call records and compromise the communications belonging to a “limited number” of people in government and politics, officials said.

The FBI declined to comment on the T-Mobile hack, while the U.S. Cybersecurity and Infrastructure Security Agency didn’t respond to a request for comment outside of regular business hours.

China has “no interest in interfering in other countries’ internal affairs through cyberspace,” Foreign Ministry spokesman Lin Jian said.

AT&T Inc. and Verizon Communications Inc. were among those breached over several months, the Journal reported last month. The hackers may have targeted the phones of Donald Trump, JD Vance and Trump family members, as well as members of Vice President Kamala Harris’ campaign staff and others, the New York Times had reported.
