(Reuters) – T-Mobile US Inc on Monday acknowledged a data breach but said it was yet to find if any customer information has been compromised, a day after an online forum alleged that personal data of more than 100 million of its users was leaked.
The telecom operator said in a blogpost that it was confident the entry point used to access the data had been closed. It did not confirm the number of affected records.
U.S.-based digital media outlet Vice first reported the claims of a data breach on Sunday.
According to the report in Vice’s Motherboard, the forum’s post does not mention T-Mobile, but the hacker told Vice they have obtained data of over 100 million people and that the data came from T-Mobile servers.
Shares of T-Mobile were down 2.8% in afternoon trading.
