Abstract

Generation of one or more models is caused based on selecting training data comprising a plurality of features including a prevalence feature for each vulnerability of a first plurality of vulnerabilities. The one or more models enable predicting whether an exploit will be developed for a vulnerability and/or whether the exploit will be used in an attack. The one or more models are applied to input data comprising the prevalence feature for each vulnerability of a second plurality of vulnerabilities. Based on the application of the one or more models to the input data, output data is received. The output data indicates a prediction of whether an exploit will be developed for each vulnerability of the second plurality. Additionally or alternatively, the output data indicates, for each vulnerability of the second plurality, a prediction of whether an exploit that has yet to be developed will be used in an attack.

Claims (38)

1. A system comprising:

storage media;

one or more processors;

and one or more programs stored in the storage media and configured for execution by the one or more processors, the one or more programs comprising instructions which, when executed by the one or more processors, cause performance of:

training a first prediction model using first training data comprising one or more features for each software vulnerability of a first plurality of software vulnerabilities, wherein the first prediction model enables computing a probability that an exploit is to be developed for a particular software vulnerability;

causing application of the first prediction model to first input data comprising the one or more features for each software vulnerability of a second plurality of software vulnerabilities;

receiving, based on the application of the first prediction model to the first input data, first output data that indicates, for each software vulnerability of the second plurality of software vulnerabilities, a probability that an exploit will be developed for said each software vulnerability.

2. The system of claim 1 , wherein the one or more programs further comprise instructions which, when executed by the one or more processors, cause performance of:

based on the first output data, causing an adjustment to prioritization for one or more of the second plurality of software vulnerabilities.

3. The system of claim 1 , wherein the one or more features indicate a number of copies of software affected by said each software vulnerability of the first plurality of software vulnerabilities.

4. The system of claim 1 , wherein the one or more features indicate a number of copies of software affected by said each software vulnerability of the first plurality of software vulnerabilities, and wherein each software vulnerability of the first plurality of software vulnerabilities has a ranking determined based on a number of copies of software affected by said each software vulnerability, and wherein the one or more prevalence features includes an indication of whether the ranking of said each software vulnerability is less than a predetermined threshold.

5. The system of claim 1 , wherein the one or more features indicate a number of references, in a database, to each software vulnerability of the first plurality of software vulnerabilities.

6. The system of claim 1 , wherein the one or more features indicate a number of products that are affected by each software vulnerability of the first plurality of software vulnerabilities.

7. The system of claim 1 , wherein the first training data further a textual description feature comprising data extracted from a textual description of each software vulnerability of the first plurality of software vulnerabilities.

8. The system of claim 1 , wherein the first training data further comprises an exploit development time feature indicating, for each software vulnerability of the first plurality of software vulnerabilities, whether an exploit for said each software vulnerability was developed within a particular number of days of publication of said each software vulnerability.

9. The system of claim 8 , wherein the first output data indicates, for each software vulnerability of the second plurality of software vulnerabilities, a prediction of whether an exploit will be developed for said each software vulnerability within the particular number of days.

10. The system of claim 1 , wherein the first output data indicates, for each software vulnerability of the second plurality of software vulnerabilities, a prediction of a number of days that will elapse between publication of said each software vulnerability and development of an exploit for said each software vulnerability.
