Abstract
In one embodiment, a device obtains execution records regarding executions of a plurality of binaries. The execution records comprise command line arguments used during the execution. The device determines measures of similarity between the executions of the binaries based on their command line arguments. The device clusters the executions into clusters based on the determined measures of similarity. The device flags the command line arguments for a particular one of the clusters as an indicator of compromise for malware, based on at least one of the binaries associated with the particular cluster being malware.
Claims20
A method comprising:
- obtaining, by a device, execution records regarding executions of a plurality of binaries, wherein the execution records comprise command line arguments used during the executions;
- determining, by the device, measures of similarity between the executions of the binaries based on their command line arguments;
- clustering, by the device, the executions into clusters based on the determined measures of similarity;
- and
- flagging, by the device, the command line arguments for a particular one of the clusters as an indicator of compromise for malware, based on at least one of the binaries associated with the particular cluster being malware.
An apparatus, comprising:
- one or more network interfaces to communicate with a network;
- a processor coupled to the network interfaces and configured to execute one or more processes;
- and
- a memory configured to store a process executable by the processor, the process when executed configured to:
- obtain execution records regarding executions of a plurality of binaries, wherein the execution records comprise command line arguments used during the executions;
- determine measures of similarity between the executions of the binaries based on their command line arguments used by the plurality of binaries during execution;
- cluster the executions into clusters based on the determined measures of similarity;
- and
- flag the command line arguments for a particular one of the clusters as an indicator of compromise for malware, based on at least one of the binaries associated with the particular cluster being malware.
A tangible, non-transitory, computer-readable medium storing program instructions that cause a device to execute a process comprising:
- obtaining, by the device, execution records regarding executions of a plurality of binaries, wherein the execution records comprise command line arguments used during the executions;
- determining, by the device, measures of similarity between the executions of the binaries based on their command line arguments;
- clustering, by the device, the executions into clusters based on the determined measures of similarity;
- and
- flagging, by the device, the command line arguments for a particular one of the clusters as an indicator of compromise for malware, based on at least one of the binaries associated with the particular cluster being malware.
