AMEAÇAS E VULNERABILIDADES EM SISTEMAS E REDES: UMA ANÁLISE CIENTÍFICA BASEADA EM EVIDÊNCIAS RECENTES

Resumo

This study analyzes key contemporary cybersecurity threats, such as malware, phishing, and ransomware, and the critical vulnerabilities that enable them, including weak credentials and outdated software. Through a systematic literature review of articles published between 2023 and 2025, the findings indicate that phishing is responsible for up to 80% of data breaches, while malware accounts for 35% of incidents. As mitigation strategies, the study discusses the implementation of multi-factor authentication (MFA), the use of Artificial Intelligence for proactive threat detection, the adoption of robust security protocols like WPA3 and TLS 1.3, and preparation for emerging risks with quantum-resistant cryptography. It is concluded that building resilient digital ecosystems requires an integrated approach, combining advanced technologies, robust organizational policies, and continuous user education to face an ever-evolving threat landscape.
