What is spyware and how does it covertly steal confidential information?

Spyware is a category of malicious software created for the covert collection of confidential information about a user without their knowledge and consent. Unlike viruses, which strive to make themselves known or harm the system, spyware operates as stealthily as possible, disguising itself as legitimate background processes or operating system services.

The main targets of such programs include intercepting keystrokes via keyloggers, taking desktop screenshots, stealing credentials for social networks and banking systems, and monitoring browser history and used applications. The collected data is regularly encrypted and sent to a remote command server of the attackers, after which the user may face financial losses or the compromise of personal correspondence.

To minimize the risks of spyware infection, the following security rules must be observed:

Protection against spyware also requires constant updates to the operating system and all software used. Timely remediation of vulnerabilities closes off the main avenues for attackers to covertly install such threats on a personal device.
