WASHINGTON — T-Mobile's network was among the systems hacked in a damaging Chinese cyber-espionage operation that gained entry into multiple U.S. and international telecommunications companies, the Wall Street Journal reported on Friday, citing people familiar with the matter.
Hackers linked to a Chinese intelligence agency were able to breach T-Mobile as part of a monthslong campaign to spy on the cellphone communications of high-value intelligence targets, the Journal added, without saying when the attack took place.
"T-Mobile is closely monitoring this industrywide attack, and at this time, T-Mobile systems and data have not been impacted in any significant way, and we have no evidence of impacts to customer information," a company spokesperson told the Wall Street Journal.
It was unclear what information, if any, was taken about T-Mobile customers' calls and communications records, according to the report.
T-Mobile did not immediately respond to a Reuters' request for comment.
On Wednesday, the Federal Bureau of Investigation and the U.S. cyber watchdog agency Cybersecurity and Infrastructure Security Agency said China-linked hackers have intercepted surveillance data intended for American law enforcement agencies after breaking into an unspecified number of telecom companies.
