A challenge in sound reverse engineering of binary executables is to determine sets of possible targets for dynamic jumps. One technique to address this challenge is abstract interpretation, where singleton values in registers and memory locations are overapproximated to collections of possible values. With contemporary abstract interpretation techniques,(More)
During the last decade, static analyzers of source code have improved greatly. Today, precise analyzers that propagate values for the program’s variables, for instance with interval arithmetic, are used in the industry. The simultaneous propagation of sets of values, while computationally efficient, is a source of approximations, and ultimately of false(More)
A key problem in reverse engineering executables is to reconstruct the programs’s control flow, i.e., to construct a graph representation of the byte sequences or paths a computer may execute as instructions. Unfortunately, exactly computing all feasible paths of a program is not possible. Therefore, the task of precise control flow reconstruction and(More)
