More than a year after the “worst telecom hack in our nation’s history” occurred, the top Democrat on the Senate Intelligence Committee says he still receives contradicting reports on whether the threat has ended.

Senate Intelligence Committee Vice Chairman Mark Warner (D-VA), a former telecom venture capitalist, told reporters at a Defense Writers Group event on Friday that he still gets “conflicting” assessments from various intelligence agencies on whether the China-linked hacking group known as Salt Typhoon can still access the data from nine of the largest U.S. telecommunication companies.
