Initially, Kevin was easily deceived by strangers' promises, but with experience, he became more cautious and learned to recognize the dangers of cyberattacks like phishing.

What is spear phishing, and why is it particularly dangerous?

Spear phishing is a targeted form of phishing where attackers impersonate a trusted sender to deceive the recipient into downloading malware. It is dangerous because it often involves customized and convincing tactics that can bypass traditional security filters.

What is the difference between malware and ransomware as described in the script?

Malware refers to malicious software that can steal or damage data, while ransomware is a specific type of malware that encrypts data and demands payment for its release.

Employees should be cautious because email attachments, particularly those with macros, can contain malware that, if activated, can compromise security. It’s advised to consult with the security department before opening such files.

What risks are associated with downloading programs from the internet?

Downloading and executing unverified programs from the internet exposes devices to malware and hacking attempts. These programs can serve as gateways for attackers to infiltrate systems.

What advice does the script offer regarding portable media devices, such as USBs?
