Which of the following is a primary method by which a Trojan horse virus typically compromises a computer system?
Self-replicating through network shared folders
Disguising itself as legitimate software to gain user trust
Exploiting hardware firmware vulnerabilities directly
Infecting system BIOS during startup
Disguising itself as legitimate software to gain user trust
A Trojan horse is a type of malware that misleads users of its true intent by appearing as legitimate software. Unlike viruses, it does not self-replicate, but instead relies on social engineering to be executed by the user.
ISO/IEC 27001
A Trojan horse is a type of malware that misleads users of its true intent by appearing as legitimate software. Unlike viruses, it does not self-replicate, but instead relies on social engineering to be executed by the user.
Impact=Vulnerability├ЧThreat тАФ Theoretical risk assessment formula in cybersecurity.
The Trojan operates on the principle of deception. Once a user executes the malicious file, believing it to be a benign utility or program, it gains the user's system privileges to perform unauthorized actions such as creating backdoors, stealing sensitive data, or installing further malware.
Trojan horses are non-replicating malware.
They require user interaction (execution) for initial activation.
They often create a 'backdoor' for remote administrative control.
Unlike worms, they do not spread automatically across networks.
Not applicable as this is malicious software.
Compromises system integrity and data confidentiality.
Difficult to detect due to masking as legitimate processes.
Remote Access Trojans (RATs) for illicit control.
Data exfiltration scripts.
Botnet recruitment.
Option A describes a Worm, which is distinct from a Trojan due to self-replication capabilities.
Option C and D refer to hardware-level or rootkit-level threats which are distinct from the typical software-level operation of a Trojan.
B is correct тАФ Trojan horses compromise systems by disguising themselves as legitimate software to manipulate users into executing them.
Always distinguish between viruses (which require host files), worms (which replicate autonomously), and Trojans (which rely on user interaction).
