SECUR-AMA: Active Malware Analysis Based on Monte Carlo Tree Search for Android Systems

PhD thesis, Concordia University. The growing popularity of Android applications has generated increased concerns over the danger of piracy and the spread of malware. A popular way to distribute malware in the mobile world is through the repackaging of legitimate apps. This process consists of downloading, unpacking, manipulating, recompiling an application, and publishing it again in an app store. In this thesis, we conduct an empirical study of over 15, apps to gain insights into the factors that drive the spread of repackaged apps.

We also examine the motivations of developers who publish repackaged apps and those of users who download them, as well as the factors that determine which apps are chosen for repackaging, and the ways in which the apps are modified during the repackaging process. We have also studied android applications structure to investigate the locations where malicious code are more probable to be embedded into legitimate applications.

We observed that service components contain key characteristics that entice attackers to misuse them. Therefore, we have focus on studying the behavior of malicious and benign services. Whereas benign services tend to inform the user of the background operations, malicious services tend to do long running operations and have a loose connection with rest of the code.

We proposed a hybrid approach using static and dynamic analysis to extract the API calls through the service lifecycle. Finally, we used the list of API calls preponderantly present in both malware as well as benign services as the feature set. We applied machine learning algorithms to use the feature set to classify malicious services and benign services. Repository Staff Only: item control page.

Analysis and Research of System Security Based on Android

Abstract: Android may be a smart mobile terminal operating platform core on Linux. But thanks to its open-source software and programmable framework character, it leads the Android system susceptible to get virus attacks. This paper has deeply researched from the Linux system security mechanism, Android-specific security mechanisms and other protection mechanisms. And on this basis, Android devices have achieved closely guarded on normal state. So that attackers cannot use the kernel module or core library to get highest access permission and be attacked. Meanwhile, to further strengthen the security of Android devices, it enables them to properly handle the high-risk threat. This paper also strengthened intrusion detection system HIDS based on the host in order to detect malicious software and strengthen the Android system-level access control.

Android is the most widely used mobile operating system OS. A large number of third-party Android application app markets have emerged. The absence of third-party market regulation has prompted research institutions to propose different malware detection techniques. However, due to improvements of malware itself and Android system, it is difficult to design a detection method that can efficiently and effectively detect malicious apps for a long time. Meanwhile, adopting more features will increase the complexity of the model and the computational cost of the system.

Analysis and Research of System Security Based on Android

This page presents several best practices that have a significant, positive impact on your app's security. When you safeguard the data that you exchange between your app and other apps, or between your app and a website, you improve your app's stability and protect the data that you send and receive. If an implicit intent can launch at least two possible apps on a user's device, explicitly show an app chooser.

There are many malware applications in Smartphone. Smartphone—whether for business or personal use—may not be protected from malwares. Thus, monitoring, detecting, tracking, and notification MDTN have become the main purpose of the writing of this paper. MDTN is meant to enable Smartphone to prevent and reduce the number of cybercrimes. The methods are shown to be effective in protecting Smartphone and isolating malware and sending warning in the form of notification to the user about the danger in progress.

Фонтейн вздохнул и обхватил голову руками. Взгляд его черных глаз стал тяжелым и неподвижным. Возвращение домой оказалось долгим и слишком утомительным. Последний месяц был для Лиланда Фонтейна временем больших ожиданий: в агентстве происходило нечто такое, что могло изменить ход истории, и, как это ни странно директор Фонтейн узнал об этом лишь случайно. Три месяца назад до Фонтейна дошли слухи о том, что от Стратмора уходит жена. Он узнал также и о том, что его заместитель просиживает на службе до глубокой ночи и может не выдержать такого напряжения. Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил.

Повисла пауза. Стратмор поднял глаза вверх, собираясь с мыслями. - Сьюзан, - наконец произнес он еле слышно.  - У меня нет семьи.  - Он посмотрел на.  - Мой брак практически рухнул.

Она посмотрела на светящиеся мониторы Стратмора, бросилась к его письменному столу и начала нажимать на клавиши. Отключить ТРАНСТЕКСТТеперь это нетрудная задача, поскольку она находится возле командного терминала. Она вызвала нужное командное окно и напечатала: ВЫКЛЮЧИТЬ КОМПЬЮТЕР Палец привычно потянулся к клавише Ввод. - Сьюзан! - рявкнул голос у нее за спиной. Она в страхе повернулась, думая, что это Хейл.

 - Можно ли с его помощью найти ключ. Джабба всплеснул руками. - Ради всего святого. Шифры-убийцы похожи на любые другие - они так же произвольны. Угадать ключи к ним невозможно.

Я читал электронную почту Танкадо уже в течение двух месяцев.

Постучите тихонько. Я найду свободную комнату и покажу вам Испанию с такой стороны, что вам будет что вспомнить, - И она сладко причмокнула губами. Беккер изобразил улыбку.

Сознание нехотя подтверждало то, о чем говорили чувства. Оставался только один выход, одно решение. Он бросил взгляд на клавиатуру и начал печатать, даже не повернув к себе монитор. Его пальцы набирали слова медленно, но решительно. Дорогие друзья, сегодня я ухожу из жизни… При таком исходе никто ничему не удивится.

 Надеюсь. - Месье Клушар.  - Беккер улыбнулся и достал из кармана пиджака ручку.

 Пусти меня, - сказала Сьюзан, стараясь говорить как можно спокойнее. Внезапно ее охватило ощущение опасности. - Ну, давай же, - настаивал Хейл.  - Стратмор практически выгнал Чатрукьяна за то, что тот скрупулезно выполняет свои обязанности. Что случилось с ТРАНСТЕКСТОМ.

Он исходил из самых патриотических соображений, но все пошло вкривь и вкось. Результатом стали смерть и предательство. Теперь начнутся судебные процессы, последуют обвинения, общественное негодование.
