Impact

For European organizations, the impact of this scanning activity is currently low to medium. While the scanning itself does not compromise systems, it signals growing interest and reconnaissance around PQC adoption, which is critical for future-proofing cryptographic security. European entities, especially those in finance, government, telecommunications, and critical infrastructure, are prime targets for adversaries preparing for the quantum era. Early detection of PQC support or lack thereof could inform attackers about which organizations are vulnerable to future quantum-enabled attacks. This reconnaissance could also be used to prioritize targets for espionage or data harvesting before quantum computers become practical. Thus, while no immediate breach or compromise occurs, the scanning activity highlights the need for European organizations to accelerate PQC readiness and monitor their cryptographic posture. Failure to do so could lead to significant confidentiality and integrity risks in the medium to long term as quantum computing advances.

Defensive guidance

European organizations should take proactive and specific steps beyond generic advice: 1) Conduct internal audits to inventory cryptographic algorithms in use, identifying any legacy or vulnerable schemes. 2) Engage with vendors and service providers to confirm PQC support or roadmap for adoption, especially for TLS, VPNs, and encryption-at-rest solutions. 3) Implement network monitoring to detect unusual scanning activity targeting cryptographic endpoints and analyze logs for PQC-related probes. 4) Participate in industry and governmental PQC transition initiatives to stay updated on standards and best practices. 5) Develop and test migration plans for hybrid cryptographic deployments that combine classical and post-quantum algorithms to ensure seamless transition. 6) Educate security teams about the implications of quantum threats and reconnaissance activities to improve incident response readiness. 7) Collaborate with national cybersecurity agencies to share threat intelligence related to PQC scanning and quantum threat actors. These measures will help European organizations reduce exposure to future quantum-enabled attacks and respond effectively to reconnaissance efforts.
