Today, the digital landscape is more interconnected than ever, making it a prime target for cyber threats. These cybercriminals are often part of complex networks or even state-sponsored groups. They continuously seek out vulnerabilities to exploit, aiming to access unauthorized data, disrupt services, or steal sensitive information.
As technology evolves, it’s important to learn from past security breaches to strengthen defenses against future attacks.
