Problems solved by technology

What's more serious is that this method utilizes the Activity management mechanism of the Android system, which is highly concealed, and it is difficult for users to detect it before, after or during the hijacking process.

Embodiment Construction

[0021] The Android system manages the Activity through a method called the Activity stack. The state of an Activity instance determines its position in the stack. In the Android system, the Activity has four basic states:

[0022] 1) Active (activate) / Runing (run):

[0023] After a new Activity is started and pushed into the stack, it will be displayed at the front of the screen and at the top of the stack. At this time, it is in an active state that is visible and can interact with the user.

[0024] 2) Paused (paused):

[0025] The state when the Activity is covered by another transparent or Dialog-style Activity. At this time, it is still connected to the window manager, and the system continues to maintain its internal state, so it is still visible, but it has lost focus and cannot interact with the user. This state is called a suspended state.

[0026] 3) Stopped (stop):

[0027] When the Activity is completely covered by another Activity, loses focus and is invisible,...

Abstract

The invention discloses a method and a device for detecting Activity hijacking risk of an Android system. The method comprises the steps of obtaining feature information of an Activity which is in an activated state at present before a target Activity enters the activated state; judging whether the Activity which is in the activated state at present accords with preset security features or not according to the obtained feature information; if not, determining that a system is in the Activity hijacking risk. According to the technical scheme, the method can be directly realized through a way of expanding system functions on the premise that the operating mechanism of the Android system is not changed, the realizing is simple, and the generality is high.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a method and device for detecting Activity hijacking risks in an Android system. Background technique [0002] Android is an open source operating system based on Linux, mainly used in portable devices such as smartphones and tablet computers. The system is developed by Java language, including operating system, middleware, user interface and application software. With the continuous development of the Android system, major hardware manufacturers are also constantly launching various products based on the Android system. At present, terminals based on the Android system have occupied an important position in the market. [0003] Activity is a basic component of the Android system, responsible for the interaction between the system and the user. In the Android system, an Activity is equivalent to a page. On the one hand, the page is used to display variou...
