Abstract: Systems and methods are provided to measure the similarity between a first and second data sample. The method can include creating a plurality of k-mers from the first data sample, each k-mer having a first length; generating a first vector from the plurality of k-mers by processing the plurality of k-mers with a plurality of hash functions; calculating a similarity level between the first and second data sample by comparing the first vector to a second vector, the second vector representing the second data sample; and based on the similarity level, determining a maliciousness level of the first data sample.

Abstract: Systems and methods are provided to determine a maliciousness level of an element using a hypergraph of neighbors. The method can include receiving the element; generating a hypergraph of neighbor target elements found in a database, the hypergraph comprising a set of nodes and a set of edges, wherein the set of nodes represents the neighbor target elements, and the set of edges represents connections between the neighbor target elements; classifying nodes and edges in the hypergraph; generating a maliciousness level profile for the element based on aggregation of nodes and edges in the hypergraph; linking information related to the element with the maliciousness level profile for the element; and performing an action based on a type of the element.
