The chairman of the House Homeland Security Committee, Rep. Mark Green (R-TN), has called on U.S. telecommunications companies affected by the widespread China-linked cyberattack known as Salt Typhoon to fully cooperate with an independent investigation into the breach. This comes amid federal efforts to address the escalating cyber threats posed by Beijing.
Salt Typhoon has already impacted at least eight major telecom firms, with federal officials admitting they are still uncertain about how the group initially gained access. The perpetrators remain embedded within the compromised networks, raising significant concerns about the ongoing threat.
A Call to Action for Accountability
In a statement, Rep. Green underscored the gravity of the breach and its unprecedented nature. “There is no doubt that a nation-state-sponsored intrusion of this scale and sophistication into internet service providers is unprecedented and unnerving,” Green said, likening the incident to the previous Volt Typhoon campaign, another cyber campaign attributed to China targeting U.S. critical infrastructure.
Green urged the impacted companies to collaborate with the Cyber Safety Review Board (CSRB) to ensure a comprehensive investigation. He emphasized the importance of understanding the full extent of the intrusion, stating that such cooperation would enable the CSRB to develop actionable recommendations for improving the resilience of U.S. telecom networks.
The Role of the Cyber Safety Review Board
The CSRB, a federal body tasked with reviewing major cyber incidents, held its first meeting today to address the Salt Typhoon campaign. Green noted that the board and the Cybersecurity and Infrastructure Security Agency (CISA) must prioritize sharing timely information with policymakers, the private sector, and the public.
He pledged that his committee would convene a hearing next year to review the board’s findings and advance legislation aimed at addressing broader cyber threats to critical infrastructure.
Proposed Legislative Measures
Green highlighted several legislative measures currently under consideration, many of which have already seen partial progress during this congressional session. These proposals include:
- Creating a Task Force on China’s Cyber Threats: A specialized group to analyze and counter Beijing’s increasingly sophisticated cyber operations.
- Securing Maritime Ports: Strengthening cybersecurity protocols at critical transportation hubs.
- Bolstering the Cyber Workforce: Expanding initiatives to train and retain skilled cybersecurity professionals in the U.S.
Bipartisan Efforts to Address the Threat
Salt Typhoon has drawn bipartisan concern on Capitol Hill. Following a classified hearing, Sen. Ron Wyden (D-OR) announced that he is working with Sen. Mark Warner (D-VA), the chair of the Senate Intelligence Committee, and other lawmakers to draft legislation addressing the vulnerabilities exposed by the Salt Typhoon campaign.
This cooperation reflects growing frustration among policymakers over the scale of Chinese cyber intrusions and the need for swift, decisive action.
FCC’s Role in Cybersecurity Regulation
As part of the federal response, Federal Communications Commission Chairwoman Jessica Rosenworcel has proposed a draft framework to regulate the cybersecurity practices of telecom companies. The FCC’s involvement marks a significant step toward ensuring that telecom providers adhere to robust security standards to prevent future breaches.
The Urgency of Cybersecurity Preparedness
Green’s statement concluded with a stark reminder of the broader implications of Salt Typhoon and similar attacks. “We face an urgent threat from our adversaries against the technology that underpins our daily lives, and we must be prepared to take decisive action,” he said.
The Salt Typhoon investigation represents a pivotal moment in the fight against state-sponsored cyber threats. As the CSRB’s work unfolds and legislative measures advance, the focus remains on fortifying U.S. critical infrastructure against future attacks.
