Which of the following is an example of an unsafe cyber practice?

Clicking on links in unsolicited emails is an example of an unsafe cyber practice because it exposes individuals to a variety of cyber threats, such as phishing attacks. Phishing is a common tactic used by cybercriminals who send emails that appear to be from legitimate sources, enticing recipients to click on links that lead to malicious websites or initiate the download of harmful software. This can result in unauthorized access to sensitive information, identity theft, or the compromise of the individual's device.

In contrast, regularly updating software, using complex passwords, and frequently backing up data are practices that enhance cybersecurity. Keeping software up to date helps patch vulnerabilities that cybercriminals might exploit. Using complex passwords makes it harder for attackers to gain access to accounts. Backing up data frequently ensures that important information is safeguarded against data loss due to malware attacks, hardware failures, or other disasters. Therefore, clicking on links in unsolicited emails stands out as a significantly dangerous practice in contrast to the others.
