What is the main purpose of spyware?

Spyware primarily serves the purpose of capturing sensitive information from users, including account data and passwords. It operates covertly on a user's device, often without their consent or knowledge, enabling it to monitor activities, collect personal information, and transmit this data to third parties. Such malicious software can compromise user security and privacy, making it highly detrimental.

While other options like creating advertisements, managing preferences, or enhancing system performance might involve legitimate software functionalities, they do not align with the primary malicious intent of spyware. Unlike these options, which are generally designed to promote user engagement or streamline user experience, spyware's focus is rooted in data theft and exploitation. This distinction highlights why capturing account data and passwords is considered the main objective of spyware.
