The outgoing administration spent its final full week hardening the digital walls, and the courts turned off an app used by 170 million Americans. The FCC, in Chairwoman Rosenworcel's closing days, voted to declare that federal wiretap law obligates carriers to secure their networks, the agency's most direct regulatory answer yet to the Salt Typhoon intrusions, over Republican objections that guaranteed the ruling a short life. The Supreme Court unanimously upheld the TikTok divest-or-ban law on January 17, and by the night of January 18 the app had gone dark for US users, the most consequential government action against a communications platform in the internet era, with service providers and app stores suddenly on the legal front line.
December opened with the quiet part said out loud: Chinese state hackers had burrowed into at least eight US telecom providers, and the government's advice to Americans was to encrypt their way around the phone network. The FCC answered within a day, moving to turn a 30-year-old wiretap statute into a cybersecurity mandate for carriers. Away from the breach, AT&T used its first analyst day in years to commit to 50 million fiber locations and a copper farewell by 2029, Britain's competition regulator blessed the 15 billion pound Vodafone-Three merger with MVNO protections attached, and eSIM Go teamed with Vodafone UK to sell the MVNO model itself as a boxed product.
The rumor became official. The FBI and CISA jointly confirmed that hackers tied to the Chinese government have compromised networks at multiple U.S. telecom companies, stealing call records and intercepting communications around court-ordered wiretap systems, and by Friday the Wall Street Journal had added T-Mobile to the list of names. Against that backdrop the deal machine kept turning: Frontier shareholders blessed Verizon's $20 billion fiber acquisition, and Charter moved to absorb Liberty Broadband and simplify the ownership of America's second-largest cable company.
The industry absorbed two shocks in a single week. The Wall Street Journal's revelation that China-linked hackers penetrated AT&T, Verizon, and Lumen — apparently through the very systems built to serve court-ordered wiretaps — turned into a full Washington firestorm, with House Energy and Commerce leaders demanding answers from all three carriers by week's end. Meanwhile, Hurricane Milton slammed into Florida days after Helene devastated the Southeast, and for the first time at scale, the FCC let T-Mobile and SpaceX switch on satellite texting for every compatible phone in the storm zone regardless of carrier. One story exposed the network's oldest vulnerability; the other previewed its newest safety net.
