What defines a wrapper in the context of Trojan virus?

Answer 1

In the context of a Trojan virus, a wrapper is a piece of software that encapsulates the Trojan payload, often disguising it as a legitimate program to deceive users into executing it. This technique enhances the Trojan's ability to bypass security measures, as the wrapper can include features like encryption, compression, or even legitimate functionality. By presenting itself as a harmless application, the wrapper increases the likelihood of user interaction, leading to the execution of the malicious code hidden inside.
