Este fork se distribu\u00eda bajo un nombre similar, mitmproxy2, y una versi\u00f3n inexistente 8.0.1 (la versi\u00f3n actual de mitmproxy es 7.0.4), con la esperanza de que los usuarios desprevenidos asumieran que el paquete era una nueva edici\u00f3n del proyecto principal (typosquatting) y quisieran probar la nueva versi\u00f3n.     <\/p>\n<p>En su composici\u00f3n, mitmproxy2 era similar a mitmproxy, salvo por los cambios en la implementaci\u00f3n de funcionalidades maliciosas. Los cambios consistieron en la eliminaci\u00f3n de la cabecera HTTP \u00abX-Frame-Options: DENY\u00bb, que proh\u00edbe el procesamiento de contenido dentro de un iframe, la desactivaci\u00f3n de la protecci\u00f3n contra ataques XSRF y la inclusi\u00f3n de las cabeceras \u00abAccess-Control-Allow-Origin: *\u00bb, \u00abAccess-Control-Allow-Headers: *\u00bb y \u00abAccess-Control-Allow-Methods: POST, GET, DELETE, OPTIONS\u00bb.     <\/p>\n<p>Los cambios mencionados eliminaban las restricciones de acceso a la API HTTP, utilizada para gestionar mitmproxy a trav\u00e9s de la interfaz web, lo que permit\u00eda a cualquier atacante en la misma red local ejecutar su c\u00f3digo en el sistema del usuario al enviar una solicitud HTTP.    <\/p>\n<p>La administraci\u00f3n del cat\u00e1logo acord\u00f3 que los cambios introducidos pod\u00edan interpretarse como maliciosos, y que el paquete en s\u00ed era un intento de promover otro producto bajo la apariencia del proyecto principal (en la descripci\u00f3n del paquete se afirmaba que era una nueva versi\u00f3n de mitmproxy, y no un fork).
