In May 2020, the company suffered another data breach where hackers gained access to its internal network again, stealing the information of hundreds of customers. The data breach was discovered in early February 2025, but the exact date when the hackers gained initial access to NTT's systems hasn't been determined. Specifically, NTT says hackers breached its 'Order Information Distribution System,' which held details on 17,891 corporate customers (companies), but no data on personal customers (consumers).

The company discovered the breach on February 5 and blocked the threat actor's access to the breached system by the next day. On January 2, 2025, the company suffered a massive 12-hour service disruption on its mobile services and payment platforms, attributed to a distributed denial of service (DDoS) attack. "NTT Communications Corporation discovered on February 5 that our facilities had been subjected to unauthorized access," reads the announcement. Being a large telecommunications service provider in Japan, NTT often becomes a target of cybercriminals looking to disrupt its operations or steal valuable data from its networks.
