In brief
Senator Mark Warner describes the breach's alarming depth, revealing potential risks to American leaders and extensive communications.
China's recent infiltration of U.S. telecommunications systems has proven to be far more extensive than initially acknowledged by the Biden administration, according to Senator Mark Warner, the chairman of the Senate Intelligence Committee. During an interview on Thursday, Warner revealed that hackers had not only gained access to systems but were also able to listen to phone calls and read text messages, employing strategies that capitalized on outdated equipment and gaps in network connectivity."The barn door is still wide open, or mostly open," Warner warned, reflecting on his shock at the breach's scope. The intelligence community has linked the cyber intrusions to a Chinese hacking group known as Salt Typhoon, which was flagged by Microsoft's cybersecurity team earlier this year. Government officials are still working to determine just how far the breach extends and what sensitive information may have been compromised, with reports indicating that prominent figures, including President-elect Donald J. Trump and Vice President-elect JD Vance, may have been monitored.Initially, it was believed that hackers primarily utilized stolen passwords to target systems authorized to access phone conversations and texts. These systems are managed by the nation's largest telecommunications providers: Verizon, AT&T, and T-Mobile. However, further investigations have uncovered a more extensive infiltration than first thought, as hackers took advantage of aging technology and weak points within the national telecommunication networks.In the aftermath of the breach being exposed, U.S. officials observed that the Chinese hackers seemed to have receded, possibly to avoid detection. However, Warner cautioned against assuming that these intruders had been fully expelled or that investigators had comprehended the full extent of their reach. "We’ve not found everywhere they are," he stated, highlighting the continued threat posed by sophisticated cyber adversaries.The committee has been kept informed through government briefings, and Warner has engaged in discussions with telecommunications executives regarding the ongoing issues surrounding the breach and its aftermath.
