DESVENDANDO BRECHAS DIGITAIS

The article addresses the growing importance of cybersecurity in the current context, where digital devices are increasingly present in daily activities. Focused on three case studies – VTech, C&A and Serasa Experian – the work examines how security flaws allowed data breaches that compromised the sensitive information of millions of people. The methodology used is bibliographic, analyzing academic sources and safety reports. The article details attack techniques, such as SQL Injection, Phishing and Brute Force, in addition to proposing measures to mitigate such threats, such as encryption, multi-factor authentication and continuous employee training. It concludes that the combination of advanced technologies and educational practices is essential to reduce cyber attacks and improve companies' digital security, but points out limitations in data on companies' responses to breaches. Finally, it recommends future research to evaluate the effectiveness of the security measures adopted.
