Pegasus is a harmful programmed malware made up of the phrase’s "malware" and "software" in the field of information technology. Pegasus is an example of a kind of malware. It may be installed without user input with a single click on Google's Android operating system and Apple's iOS. Hackers may randomly run spyware in software systems, or uninformed individuals may carelessly accept and install malware when browsing the internet or reading emails. Ransomware may sometimes seriously harm the linked machine by destroying data and disrupting software operations when they shouldn't be running. Because of this, it is crucial to spot harmful applications before they are put into use. The bulk of current collision avoidance research has been on learning algorithms that analyze behavior. Businesses are hesitant to recognize infections that are unknown to them despite this. This research study describes a computational strategy for identifying hidden computer Pegasus malware relies on feature extraction methods, such as specific tree structure and networking methods. Testing is carried out to determine the efficacy of the suggested technique.
