Run-time additive disinfection of malware functions
View Patent ↗In embodiments of the present invention improved capabilities are described for runtime additive disinfection of malware. Runtime additive disinfection of malware may include performing the steps of identifying, based at least in part on its type, an executable software application that is suspected of being infected with malware, wherein the malware is adapted to perform a function during the execution of the executable software application, predicting the malware function based on known patterns of malware infection relating to the type of the executable software application, and in response to the prediction, adding a remediation software component to the executable software application that disables the executable software component from executing code that performs the predicted malware function.
1. A computer program product embodied in a non-transitory computer readable medium that, when executing on one or more computers, performs the steps of:
scanning code and discovering that the code is infected with malware;
based on information obtained during the scan, predicting a function of the malware that presents a malware threat based on known patterns of malware infection relating to a type of executable software containing the code;
in response to the prediction, adding a remediation software component to the code, the remediation software component providing a shell for the code that (a) permits the code to execute whereby original content of the code remains, and (b) disables execution of the function that is predicted to present the malware threat external to the shell, thereby remediating the malware threat by externally neutralizing the infection;
identifying an unintended result of the remediation software component; and
removing the remediation software component from the code at or prior to runtime of the code to restore the code to an original form.
2. The computer program product of claim 1 , wherein the code is at least one of a file, a script, an interpreted content, an executable software application, and executable code.
3. The computer program product of claim 1 , wherein the step of predicting is at least one of accomplished at runtime of the code and accomplished prior to runtime of the code.
4. The computer program product of claim 1 , wherein the step of adding the remediation software component is at least one of accomplished at runtime of the code and accomplished prior to runtime of the code.
5. A computer program product embodied in a non-transitory computer readable medium that, when executing on one or more computers, performs the steps of:
identifying an executable software application that is suspected of being infected with malware based at least in part on a type of the executable software application, wherein the malware is adapted to perform a function that presents a malware threat during the execution of the executable software application;
predicting the function based on known patterns of malware infection relating to the type of executable software application; and
in response to the prediction, adding a remediation software component to the executable software application that provides a shell for the code that (a) permits the executable software application to execute whereby original content of the executable software application remains, and (b) disables execution of the function that is predicted to present the malware threat external to the shell, thereby remediating the malware threat by externally neutralizing the infection;
identifying an unintended result of the remediation software component; and
removing the remediation software component from the executable software application at or prior to runtime of the executable software application to restore the executable software application to an original form.
6. The computer program product of claim 5 , wherein the step of predicting is at least one of accomplished at runtime of the executable software application and accomplished prior to runtime of the executable software application.
7. The computer program product of claim 6 , wherein the step of predicting is performed on a client prepared to execute the executable software application.
8. The computer program product of claim 6 , wherein the step of predicting is performed on a server and a request to make the prediction is communicated from a client prepared to execute the executable software application.
9. The computer program product of claim 5 , wherein the step of adding the remediation software component is at least one of accomplished at runtime of the executable software application and accomplished prior to runtime of the executable software application.
10. The computer program product of claim 9 , wherein the remediation software component is resident on the client prior to being added to execute the executable software application.
11. The computer program product of claim 9 , wherein the remediation software component is delivered from a server application based on a request from a client prepared to execute the executable software application.
12. The computer program product of claim 5 , wherein the remediation software component is communicated to a client prepared to execute the executable software application from a server based on a security policy.
13. The computer program product of claim 5 , wherein the step of predicting is in part based on a likelihood of the type of executable software application including malware.
14. The computer program product of claim 5 , wherein the step of predicting is in part based on a likelihood of malware with a particular function being included in the type of executable software application.
15. The computer program product of claim 5 , wherein the step of predicting is in part based on a likelihood of the type of executable software application spreading an infection related to the malware.
16. A computer program product embodied in a non-transitory computer readable medium that, when executing on one or more computers, performs the steps of:
identifying an executable software application that is suspected of being infected with malware, wherein the malware is adapted to perform a function that presents a malware threat during the execution of the executable software application;
predicting an occurrence of the function based on known patterns of malware infection relating to the executable software application; and
in response to the prediction, adding a remediation software component to the executable software application that provides a shell that (a) permits the executable software application to execute whereby original content of the executable software application remains, and (b) disables execution of the function that is predicted to present the malware threat external to the shell, thereby remediating the malware threat by externally neutralizing the infection;
identifying an unintended result of the remediation software component; and
removing the remediation software component from the executable software application at or prior to runtime of the executable software application to restore the executable software application to an original form.
