What is PsittacosaurusMongoliensis

PsittacosaurusMongoliensis is a malicious browser extension discovered during routine investigations of dubious websites. It targets Google Chrome and Microsoft Edge browsers, modifying their appearance and operation through its permissions to manage applications, extensions, themes, and other settings/content. The extension can exploit browser vulnerabilities, opening an avenue for further infection. It also uses the “Managed by your organization” feature possessed by both Chrome and Edge, which complicates the malicious software’s removal. PsittacosaurusMongoliensis has data-tracking abilities, collecting information such as browsing and search engine histories, Internet cookies, stored usernames/passwords, personally identifiable details, and saved credit card numbers. This data can then be sold to third parties or otherwise abused for profit. PsittacosaurusMongoliensis specifically targets Google Chrome and Microsoft Edge browsers. It modifies the browsers’ settings, including the home page, new tab page, and default search settings, without the user’s permission.
