Análisis de malware en Android

Trabajo de Fin de Grado en Grado en Ingeniería Informática, Facultad de Informática UCM, Departamento de Arquitectura de Computadores y Automática, Curso 2020/2021In the XXI century, the world has witnessed the creation, development and proliferation of mobile devices until the massive usage apparent nowadays. The portability, instantaneity and ease of use that these devices offer has encouraged the great majority of the population to have one of them at arm’s length. Thus, these devices have become a coveted target for malicious developers. This is the reason why the security of mobile devices has become a vital topic that must be addressed, since a suitable solution has yet to be found. From this necessity arises the present work, in which we elaborate the beginning of a response that serves as a starting point to promote further development that achieves the desired objective. With Android being the most representative Operating System among mobile devices, we are going to study the analysis of malware on Android and develop a static and dynamic antivirus based on signatures, permissions and logs, since they will prove useful when trying to detect malicious applications.En el siglo XXI se ha podido apreciar la aparición, desarrollo y proliferación de los dispositivos móviles hasta llegar a la masificación que tiene lugar en la actualidad. La portabilidad, instantaneidad y facilidad de uso que ofrecen ha hecho que la mayoría de la población tenga uno siempre al alcance de su mano. Es por ello que se han convertido en un objetivo codiciado por los desarrolladores de programas maliciosos. Así pues, la seguridad de estos dispositivos se ha convertido en un punto clave que debe ser abordado, ya que hasta la fecha no se ha encontrado una solución apropiada. De esta necesidad surge el presente trabajo, en el que elaboramos el comienzo de una respuesta que sirve como punto de partida para fomentar un posterior desarrollo que alcance el objetivo deseado. Siendo Android el sistema operativo más representativo entre los dispositivos móviles, vamos a hacer un estudio del análisis del malware en Android y a desarrollar un antivirus estático y dinámico basado en firmas, permisos y logs, pues estas evidencias serán de gran ayuda en la labor de detección de aplicaciones maliciosas.Depto. de Arquitectura de Computadores y AutomáticaFac. de InformáticaTRUEunpu

Inflammation and breast cancer. Metalloproteinases as common effectors of inflammation and extracellular matrix breakdown in breast cancer

Two rapidly evolving fields are converging to impact breast cancer: one has identified novel substrates of metalloproteinases that alter immune cell function, and the other has revealed a role for inflammation in human cancers. Evidence now shows that the mechanisms underlying these two fields interact in the context of breast cancer, providing new opportunities to understand this disease and uncover novel therapeutic strategies. The metalloproteinase class of enzymes is well studied in mammary gland development and physiology, but mostly in the context of extracellular matrix modification. Aberrant metalloproteinase expression has also been implicated in breast cancer progression, where these genes act as tumor modifiers. Here, we review how the metalloproteinase axis impacts mammary physiology and tumorigenesis and is associated with inflammatory cell influx in human breast cancer, and evaluate its potential as a regulator of inflammation in the mammary gland
