Spyware
Spyware is like having a spy living in your computer. It watches everything you do - websites you visit, things you type, files you open - and reports back to whoever installed it. Some spyware can even turn on your webcam or microphone.
What is Spyware?
Malicious software that secretly monitors and collects information about a user's activities, including browsing habits, keystrokes, and personal data, without their knowledge.
Why Should You Care?
Spyware directly compromises the confidentiality of sensitive business and personal data—from employee credentials to financial information and intellectual property—often undetected until significant damage occurs. Organizations infected with spyware face regulatory compliance violations, customer trust erosion, and potential litigation. Even a single compromised endpoint can provide attackers sustained access to internal systems and communications, making spyware detection and prevention a critical baseline control for any mature security program.

Real-World Example
Commercial surveillance spyware such as Pegasus has been used to compromise mobile devices and capture private communications, photos, microphone audio, and location data over extended periods. A targeted user may not realize their device is compromised until months of communications have been exfiltrated, demonstrating spyware's value to attackers seeking persistent surveillance rather than a one-time data theft.
