Malicious Code and Cybersecurity Attacks

The video tutorial discusses various methods attackers use to gain access to systems, including social engineering, default credentials, and misconfigurations. It highlights the importance of understanding malicious code, which can be packaged in executables, scripts, or other forms. The tutorial emphasizes the need for strong defenses like antimalware, firewalls, and user training. Real-world examples, such as the WannaCry ransomware, British Airways cross-site scripting, and Estonian SQL injection attacks, illustrate the impact of these threats.
