Cisco Cyber Security Practice Exam

Which of the following is NOT a common type of cyber attack?

1. Phishing

2. Ransomware

3. Buffer overflow

4. Spam

The correct answer is: Spam

The selection of spam as the option that is not a common type of cyber attack stems from a nuanced understanding of what constitutes a cyber attack versus other forms of cyber activity. Phishing, ransomware, and buffer overflow are all direct tactics utilized by attackers with the intent to exploit vulnerabilities, steal data, or cause disruptions to systems. Phishing involves deceptive messages to trick individuals into revealing sensitive information, such as usernames and passwords. Ransomware is malicious software designed to block access to a system until a ransom is paid. Buffer overflows occur when data exceeds the storage capacity of a buffer, potentially allowing attackers to execute arbitrary code on a system. In contrast, while spam refers to unsolicited and often irrelevant messages sent in bulk, it does not inherently represent an attack. Spam is more associated with marketing tactics or a means to clutter inboxes rather than direct malicious intent aimed at compromising security or exploiting vulnerabilities. Therefore, while spam may be annoying and can occasionally lead to malicious outcomes (like directing users to phishing sites), it fundamentally differs from the cyber attack types mentioned in the question.
