AT&T and Verizon are blocking the release of Salt Typhoon security assessment reports, according to a U.S. senator. The telecommunications giants are preventing public disclosure of findings related to a major cybersecurity threat that has targeted critical infrastructure. This obstruction comes amid growing concerns about telecom security vulnerabilities and foreign state-sponsored hacking operations.

The Salt Typhoon campaign, attributed to Chinese state actors, has compromised multiple U.S. telecommunications providers over the past year. These sophisticated attacks have potentially exposed sensitive communications data and network infrastructure details. The blocked reports likely contain crucial information about the scope of the breaches, methods used by attackers, and recommendations for improving security posture.

Senator Ron Wyden has publicly criticized the companies' decision to withhold the assessment findings from public view. The obstruction raises questions about corporate transparency in cybersecurity incidents and whether telecom companies are prioritizing reputation management over public safety. The blocked reports could provide valuable insights for other organizations facing similar threats and help strengthen national cybersecurity defenses against persistent adversaries.
