The Pentagon assesses Israeli counterintelligence activity as a “critical” threat in connection with possible spying on US officials, according to reporting from two outlets. The concern centers on tradecraft and operational risks that could affect US personnel, including the use of burner phones and heightened caution around where officials stay and how they communicate. One report says US counterintelligence believes such measures indicate a serious risk environment, while another describes the practical steps officials may take in response—such as exercising caution when staying in hotels and relying on secure communication practices. The coverage frames the issue as an intelligence and security concern rather than as a public claim of a specific confirmed operation. Both accounts emphasize that the Pentagon’s message is primarily aimed at alerting officials to potential exposure and encouraging protective behavior. Neither outlet provides detailed, publicly verifiable evidence in its excerpted material about a specific incident or outcome, but both report that the US government views the counterintelligence risk level as high.
