What is BosTaurus

BosTaurus is identified as a malicious browser extension that can take control of a user’s browser to inject advertisements, redirect searches, and modify browser settings without consent. It is considered a browser hijacker due to its ability to alter browser behavior and redirect user searches to generate revenue for its creators. Once installed, BosTaurus can change the default search engine of the browser to a different one, often a shady third-party search engine that redirects queries through its system. This redirection is used to generate advertising revenue for the extension’s creators through affiliate marketing schemes. BosTaurus primarily targets popular web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari. It uses the Managed by your organization policy, particularly in Chrome and Edge, to make it more difficult for users to remove the extension. Users are advised to exercise caution when installing software and to use security software to detect and remove such unwanted applications.
