This article discusses how advances in quantum computing put current encryption systems at risk and proposes solutions based on post-quantum cryptography. It reviews quantum-resistant algorithms, such as CRYSTALS-Kyber and SPHINCS+, and highlights transition strategies for organizations, such as hybrid cryptography. This study is essential for preparing digital systems against future threats, combining theory, business perspective, and emerging NIST standards. DOI:
The Biggest Cyberattacks in History: Key Cases and What We Learned
Ranking Methodology: criteria (cost, reach, criticality, persistence) To rank the “biggest cyberattacks in history,” I applied four criteria that, combined, give a truer picture than
