UPDATE T-Mobile US Inc.’s (NASDAQ: TMUS) network was among those recently breached by Chinese hackers in an attack on multiple telecommunications companies. The FBI and the Cybersecurity and Infrastructure Security Agency (CISA) said last week that China-linked hackers compromised U.S. networks operated by AT&T (NYSE: T), Verizon (NYSE: VZ) and Lumen (NYSE: LUMN) Inside Towers reported.
“T-Mobile is closely monitoring this industry-wide attack,” a company spokesperson told Bloomberg. “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 Chinese state-sponsored hackers perpetrated a “broad and significant cyber-espionage campaign” in which they breached multiple telecoms. 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, according to Bloomberg.
China has “no interest in interfering in other countries’ internal affairs through cyberspace,” Foreign Ministry spokesman Lin Jian said last Thursday.
