What is a common sign of a phishing attack?

• A. Unusual hardware failures
• B. Inaccessible network drives
• C. Receiving emails that appear to come from trusted sources
• D. High CPU usage from server components

Answer: (C)

Receiving emails that appear to come from trusted sources is a common sign of a phishing attack. In these scenarios, attackers often spoof the email addresses of reputable organizations or individuals to deceive recipients. The aim is to trick users into providing sensitive information, such as passwords, credit card details, or other personal data. Phishing emails may include urgent messages or enticing offers designed to provoke a quick response, often leading users to click on malicious links or download harmful attachments.

The other options do not accurately reflect typical indicators of a phishing attack. Unusual hardware failures and high CPU usage from server components are more likely associated with system malfunctions or resource overutilization rather than phishing attempts. Inaccessible network drives might indicate network issues or configuration problems, rather than a malicious act targeting user credentials or data through fraudulent communications. Therefore, recognizing emails that mimic trusted sources is crucial for identifying potential phishing threats.
