With reference to cybersecurity threats and malicious software mechanisms, consider the following statements:
1. A computer worm can self-replicate and spread across computer networks autonomously without needing to attach itself to an existing host file or program.
2. A Trojan horse actively replicates itself and infects other files across the operating system once executed by the user.
Which of the statements given above is/are correct?
- 1 onlyAnswer
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Answer
Statement 1 only is correct. A computer worm is a standalone malware program that replicates itself in order to spread to other computers across network links without needing a host program or human action. Conversely, a Trojan horse relies on tricking a user into executing it and does not replicate or spread automatically like viruses or worms.
The statement identifying worms as autonomous, host-independent malware is accurate. Computer worms exploit network protocols and system vulnerabilities to replicate across nodes without requiring user interaction or attaching to executable host code. Conversely, Trojan horses hide malicious payloads inside seemingly harmless files and do not possess self-replication routines.
