What type of threat does not need to be attached to other software? instead, it is hidden in software that appears to do one thing, and yet it does something else.
- A.
Worm
- B.
Spyware
- C.
Trojan horse
- D.
Virus
- E.
Grayware
Correct Answer
C. Trojan horseExplanation
A trojan horse is a type of threat that does not need to be attached to other software. Instead, it is hidden in software that appears to do one thing, but actually performs malicious activities in the background. Unlike viruses or worms that need to attach themselves to other files or programs to spread, a trojan horse disguises itself as legitimate software to deceive users into installing it. Once installed, it can perform various harmful actions such as stealing sensitive information, damaging files, or allowing unauthorized access to the system.Rate this question:
