Top executives from AT&T, Verizon, and Lumen Technologies have been called upon by a congressional committee to provide detailed information regarding recent cyberattacks reportedly conducted by Chinese hackers. These breaches have raised significant concerns, especially over the potential compromise of U.S. law enforcement’s wiretap systems.
The hacks, attributed to a group known as Salt Typhoon, were initially reported by The Wall Street Journal last week. The House Energy and Commerce Committee, which oversees telecommunications issues, is now seeking answers from the telecom giants to better understand the scope of these attacks and the steps being taken to prevent further disruptions.
In letters addressed to the CEOs of the companies, lawmakers expressed alarm, noting that the increasing frequency and severity of such cyberattacks have exposed vulnerabilities within the U.S. telecommunications networks. The panel emphasized the importance of safeguarding customer data and maintaining the security of essential communication services.
The committee posed eight key questions to the executives, focusing on how and when the companies became aware of the breaches, what information was compromised, and the steps taken to alert law enforcement agencies. Lawmakers have requested a briefing from the companies by October 18, underscoring the urgency of the situation.
“With Americans heavily relying on your services for communication and connectivity, the integrity of your networks is paramount,” the letter stated. “Cybersecurity protocols must be strengthened to protect Americans’ data from increasingly sophisticated foreign attacks.”
In a parallel move, the House Select Committee on China has also requested a briefing from the telecom companies, reflecting broader national security concerns tied to these cyber intrusions.
Senator Ron Wyden (D-OR), a member of the Senate Intelligence Committee, has similarly taken action, sending a letter to the Department of Justice and the Federal Communications Commission (FCC). Wyden urged these agencies to initiate the rulemaking process to update federal cybersecurity standards, with financial penalties for telecoms that fail to comply. He stressed that the current regulatory framework is outdated and ineffective in protecting against cyberattacks.
“The DOJ’s failed approach to combating cyberattacks by shielding negligent corporations must be addressed,” Wyden wrote, calling for stricter penalties and enhanced regulations.
The involvement of Chinese hacking groups in breaching major U.S. telecom networks represents a serious threat to both economic and national security. As investigations and briefings unfold, lawmakers are pushing for more robust measures to defend the nation’s critical infrastructure from foreign cyber threats.
