Read the following passage about the urban shift and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions.

[I] In an increasingly digital world, the threat posed by virus writers and hackers is ever-present. [II] These individuals use their skills to exploit vulnerabilities in computer systems, often leading to significant financial and personal information loss. [III] Virus writers create malicious software - viruses, worms, and ransomware - to infiltrate systems, whereas hackers might break into systems for various motives, including curiosity, financial gain, or political activism. Understanding their methods is crucial in mitigating risks. [IV]

Typically, virus writers operate by identifying security flaws in software and systems. Once a vulnerability is found, they design code that can infect devices, often propagating through networks or external devices. Hackers, meanwhile, may use similar tactics but often engage in more extensive infiltration activities, stealing sensitive data instead of merely causing disruption.

Protection against these threats involves not only technical measures, such as firewalls and antivirus software, but also awareness and education among users. By recognizing suspicious behaviors, such as unsolicited emails or unfamiliar software installations, individuals can protect themselves from potential attacks.

Ultimately, as technology evolves, so too must our strategies for defending against these cyber adversaries. Understanding the motivations and techniques of virus writers and hackers can empower individuals and organizations to take proactive measures in safeguarding their digital environments.

The word "propagating" in paragraph 2 refers to ______.
