Cybersecurity staff at US phone provider T-Mobile identified and expelled Chinese hackers from its network in 2024 during a spate of industry-wide hacks by Beijing to steal customer data, and Bloomberg has now published a report on the event.   T-Mobile’s security team resorted to an unusually low-tech fix for a high-tech problem in 2024, physically severing a network cable to cut off Chinese state-backed hackers’ access to its systems.[1]

Google’s Threat Intelligence Group (GTIG) has warned that at least two hacking groups are exploiting public blockchains to conceal and control malware, using a technique called “EtherHiding” that turns decentralized ledgers into resilient command-and-control (C2) infrastructure.  GTIG reports it has observed the North Korean (DPRK) threat actor UNC5342, also known as BeaverTail, employing EtherHiding since February 2025, possibly the first known instance of a nation-state group using the method.
