Abstract: Embodiments of the invention provide a method for disassembling firmware. A binary firmware image is received. If portions of the image are compressed, those portions are uncompressed. The binary firmware image is divided using a sliding window into a plurality of segments. Segments of the plurality of segments are classified as file types. Code file types are identified among the classified segments of the plurality of segments. Code architectures of the identified code file types of the classified plurality of segments are then classified. At least the classified code file types of the binary firmware image are disassembled based on the classified code architecture. The disassembled binary firmware image is evaluated for malware.
