11. A system for predicting security threat attacks, the system comprising: an identification module, stored in memory, that: identifies candidate security threat targets with latent attributes that describe features of the candidate security threat targets; and identifies historical attack data that describes which of the candidate security threat targets experienced an actual security threat attack; a determination module, stored in memory, that determines, as part of a software security prediction program, similarity relationship between latent attributes of at least one specific candidate security threat target and latent attributes of the candidate security threat targets that experienced the actual security threat attack according to the historical attack data by analyzing a matrix that indicates that the actual security threat attack targeted the candidate security threat targets by populating a respective entry of the matrix at each intersection between a vector of the matrix that corresponds to the actual security threat attack and each vector of the matrix that corresponds to the candidate security threat targets that experienced the actual security threat attack; a prediction module, stored in memory, that predicts, as part of the software security prediction program based on the determined similarity relationship, that the specific candidate security threat target will experience a future security threat attack; a performance module, stored in memory, that performs, as part of the software security prediction program, at least one remedial action to protect the specific candidate security threat target in response to predicting the future security threat attack, wherein the candidate security threat targets comprise enterprise organizations that include customers of a vendor of the software security prediction program; and at least one physical processor configured to execute the identification module, the determination module, the prediction module, and the performance module.

The system of claim 11 , wherein the matrix identifies: the enterprise organizations as corresponding to one of rows and columns of the matrix; and security threat attacks corresponding to the other of the rows and columns of the matrix.
