At least 8 US telcos, dozens of countries impacted by Salt Typhoon breaches, White House says

U.S. officials disclosed the Salt Typhoon campaign, a likely China-linked, long-running cyber espionage operation that breached multiple major telecommunications companies (including Verizon, AT&T, T-Mobile, Lumen) across dozens of countries, giving actors broad access to communications metadata and potentially privileged communications of senior officials; agencies (CISA, FBI, NSC) are coordinating remediation and urging stronger telecom cybersecurity standards.
