We shouldn’t have to say it, but China is not our friend.
(CNN) — Top telecom executives met with US national security officials at the White House on Friday as concerns mount over a long-running Chinese cyber-espionage campaign that has targeted some of the most senior US political figures in the country.
The hackers burrowed deep into some major US telecom providers to spy on phone calls and text messages and have proved difficult to kick out of some networks, people briefed on the matter said.

The hack is shaping up to be one of the biggest cyber and national security challenges facing the incoming Trump administration.
It is “by far” the “worst telecom hack in our nation’s history,” Sen. Mark Warner, Democrat of Virginia and chairman of the intelligence committee, told CNN.
But the full scope of the hack, who it affects and its impact on national security are still being investigated.
The FBI has notified fewer than 150 victims, most in the Washington, DC, area, according to Warner. But all of those victims have likely called or sent texts to numerous people, meaning the number of records accessed by the hackers is likely far greater. The hackers could listen to the calls of specific targets for certain periods of time, according to Warner.
US officials and private cyber experts are keeping a running tally of the number of telecom firms breached. US broadband and internet providers AT&T, Verizon and Lumen have all been targeted in the hacking effort, CNN previously reported.
