Abstract

Methods and systems for mitigating the effects of a malicious software application are disclosed. A dedicated module on the computing device receives from a malicious software detector a message indicating whether the application is malicious or has a malicious component. The dedicated module obtains a set of permissions to be granted to the application, and instructs software on the computing device that controls the permissions of the application to grant the set of permissions.

Claims (38)

1. A method for mitigating the effects of a malicious software application on a computing device, the method being performed by a dedicated module located on the computing device, the method comprising:

the dedicated module executing the application using a program for executing unverified applications, wherein the program provides a controlled set of resources for the application to use while executing;

the dedicated module recording behavior information pertaining to a monitored behavior of the application;

the dedicated module forwarding the behavior information to a malicious software detector remote from the computing device;

the dedicated module receiving from the malicious software detector a message indicating that the application is malicious or has a malicious component; and

in response to receiving the message from the malicious software detector, the dedicated module instructing software on the computing device that controls permissions of the application to inhibit at least one but not all permissions granted to the application.

2. The method of claim 1 , wherein at least one permission is received from the malicious software detector.

3. The method of claim 1 , wherein the dedicated module communicates with the malicious software detector through a wireless network.

4. The method of claim 1 , wherein the behavior information comprises at least one of:

a resource consumed by the application;

data accessed by the application; and

another application accessed by the application.

5. The method of claim 1 , further comprising comparing the behavior information with data stored on memory on the computing device to determine if the application is malicious or has a malicious component.

6. A system for mitigating the effects of a malicious software application on a computing device, the system comprising:

a dedicated module on the computing device comprising computer executable instructions for executing the application using a program for executing unverified applications, wherein the program provides a controlled set of resources for the application to use while executing, recording behavior information pertaining to a monitored behavior of the application, forwarding the behavior information to a malicious software detector remote from the computing device, and receiving from the malicious software detector a message indicating that the application is malicious or has a malicious component; and

an applications control module on the computing device comprising computer executable instructions for controlling the permissions of the application, the dedicated module configured to instruct the applications control module to inhibit at least one but not all permissions granted to the application in response to receiving the message from the malicious software detector.

7. The system of claim 6 , wherein at least one permission is received from said malicious software detector.

8. The system of claim 6 , wherein the dedicated module and the malicious software detector are configured to communicate through a wireless network.

9. The system of claim 6 , wherein the behavior information comprises at least one of:

a resource consumed by the application;

data accessed by the application; and

another application accessed by the application.

10. The system of claim 6 , further comprising memory on the computing device for storing data to be compared to the behavior information, the dedicated module being configured to compare the behavior information with said data to determine if the application is malicious or has a malicious component.

11. The system of claim 6 , wherein the computing device comprises a mobile device.

12. A non-transitory computer-readable medium having stored thereon computer-readable instructions for mitigating the effects of a malicious software application on a computing device, the computer-readable instructions comprising instructions for:

executing the application using a program for executing unverified applications, wherein the program provides a controlled set of resources for the application to use while executing;

recording behavior information pertaining to a monitored behavior of the application;

forwarding the behavior information to a malicious software detector remote from the computing device;

receiving from the malicious software detector a message indicating that the application is malicious or has a malicious component; and

in response to receiving the message from the malicious software detector, instructing software on the computing device that controls permissions of the application to inhibit at least one but not all permissions granted to the application.

13. The computer-readable medium of claim 12 , wherein at least one permission is received from said malicious software detector.

14. The computer-readable medium of claim 12 , further comprising instructions for communicating with the malicious software detector through a wireless network.

15. The computer-readable medium of claim 12 , wherein the behavior information comprises at least one of:

a resource consumed by the application;

data accessed by the application; and

another application accessed by the application.

16. The computer-readable medium of claim 12 , further comprising instructions for comparing the behavior information with data stored on memory on the computing device to determine if the application is malicious or has a malicious component.

17. The computer-readable medium of claim 12 , wherein the computing device comprises a mobile device.
