T-Mobile records the latest data breach when replacing the SIM card

[ad_1]

T-Mobile is still suffers from data breaches, although his latest headache may be more reflective of the telephone business as a whole. The carrier has confirmed to Bleeping Computer resulting in a recent data breach SIM card replacement attacks. The intruders compromised a “very small number” of users by converting SIM cards or viewing “limited” account information, T-Mobile said.

It is not clear which methods the attackers used, but SIM replacements are often used to take control of Internet accounts and circumvent two-factor SMS-based authentication. Attacks sometimes rely on fraud or paying the carrier’s staff to make a replacement.

The service provider said he “quickly corrected” the problem using existing measures and took further steps to protect the targets. The company also claimed that replacements are “a common occurrence throughout the industry”. While this is unfortunately true, it will not be of much help to victims – it could be a long time before SIM card replacement attacks are impractical.
