Which type of information gathering is considered passive?

• A. Port scanning on the target
• B. Monitoring network traffic
• C. Gathering data without engaging the target
• D. Conducting phishing attacks

Answer: (C)

Passive information gathering involves collecting data without directly interacting with or alerting the target to the activity. This type of reconnaissance is crucial for ethical hackers because it allows them to gather valuable intelligence without the risk of detection. By focusing on publicly available information, a hacker can create a profile of the target, discovering vulnerabilities or weaknesses without drawing attention. Gathering data without engaging the target typically includes methods such as searching through public records, social media, or other online resources for information that may reveal useful insights into the target’s operations, employees, or security postures. This unobtrusive approach minimizes the likelihood of triggering any defensive measures from the target, making it an effective strategy in the early stages of security assessments. In contrast, actions such as port scanning, monitoring network traffic, and phishing attacks are more intrusive and can easily attract the attention of the target's security team, potentially leading to countermeasures or alerts being raised. Therefore, the correct answer reflects the essence of passive information gathering, which is defined by its non-intrusive nature.
