Abstract

As digitally connected lifestyles continue to grow, cybercrime issues threaten not only an individual's but also the security interests of a country. This review explores how even minute breaches in cybersecurity might become effective and actual national threats. The aim is to examine all types of cybercrime, including unlawful access, web hijacking, child exploitation, and cyberbullying, and their prospects for disruptions to infrastructures and government operations. One major vulnerability includes the human element, such as falling for phishing attacks, weak passwords, and failure to patch systems. This paper takes a case study on how individual mistakes can jeopardize an entire nation, for instance, how the attack on Ukraine's power grid in 2015 or the WannaCry ransomware attack happened and whose is it to prevent such tragedies? Conclusion The conclusion emphasizes the need to have cybersecurity awareness and vigilance at the personal level.
