This type of PUP creates a new vulnerability on a host or system. PUPs as a Security Threatįrom a computer security perspective, the second category of PUPs is more concerning. Primarily, a user voluntarily downloads these types of PUPs. The user may be tricked into downloading the program as part of a bundle or a complicated EULA (End User License Agreement). Many of you are probably familiar with the fact that these types of programs can capture your browsing data, redirect you to different websites, they can slow down your computer, slow down your internet browsing experience, and they could force you to use a proxy and other types of unwanted actions.įor most of the PUPs a user downloads the program by choice. Within the nuisance category of PUPs, you can add in all the spyware, adware, browser related extensions, pop-up programs and so forth. I would actually characterize PUPs into two distinct categories nuisance programs and security threats.
What is a PUP?įirst, PUPs go by many names, including bundleware, junkware, adware and for mobile devices, Potentially Unwanted Applications (PUAs). Computer security courses cover malicious software (malware), but the material rarely address Potentially Unwanted Programs (PUPs).
