A method for obtaining coverage-guided fuzzing of software on a hardware target. The hardware target includes a breakpoint register, and is designed to stop an execution of the software prior to execution of an instruction of the software if the instruction is reached during the execution of the software; a memory address of the instruction is set in the breakpoint register. The method includes setting a first breakpoint prior to a first instruction of the software; executing or continuing a fuzzing iteration of the software; first checking whether the first breakpoint is reached while executing or continuing the fuzzing iteration; storing a piece of log information that includes that the first instruction in the fuzzing iteration has been reached, and optionally deleting the first breakpoint if the first check is positive. The coverage-guided fuzzing of the software includes the piece of log information.

Coverage-guided fuzzing via dynamic instrumentation

A computer-implemented method for fuzzing a target software running on a computer. In the method: a target program is carried using first input data, memory context information of the target program's run is captured, a machine learning model is trained using the first input data and the memory context information as model input, a fuzzing input is generated based on an output of the machine learning model, the target program is tested using the fuzzing input.

Method for fuzz testing

A method for communicating data requests to one or more data sources. The method includes receiving a data request, with which data of one or more data types are requested, from an application, and checking the availability of one or more data sources that are able to provide the one or more requested data types. The method further comprises: if at least one of the one or more data sources is available, sending a request to the available data source for the requested associated data type that the data source can provide; and, if no data source is available for at least one of the requested data types, sending a request for this data type to a placeholder module.
