PUPs
Commercial keyloggers are applications designed to harvest user interactions with a computer. These interactions include the capture of keystrokes, usernames and passwords, screenshots, collection of images and sound from the microphone/camera, printed documents, browser history, emails, chat logs, and more. Commercial keyloggers are similar to Infostealers in their ability to covertly collect user information, but differ in the fact that these programs can be obtained with a legitimate license through legal means. Commercial keyloggers are often marketed toward concerned spouses/parents who wish to monitor usage of a home PC, corporate IT/security teams maintaining DLP protocols, and auditors checking for conformity to policy.
Commercial keyloggers are often polished applications featuring huge selections of monitoring and stealth capabilities to assist users in maintaining a long-term presence. Due to the low cost and vast availability of these types of applications, commercial keyloggers have long been a preferred choice for criminals seeking a low barrier of entry for identity theft and fraud activities.
