Reverse engineering is a process focused on gaining an understanding for the intricaciesof a system. This practice is critical in cybersecurity as it promotes the findings and patching of vulnerabilities as well as the counteracting of malware. Disassemblers and decompilers have become essential when reverse engineering due to the readability of information they transcribe from binary files. However, these tools still tend to produce involved and complicated outputs that hinder the acquisition of knowledge during binary analysis. Cognitive Load Theory (CLT) explains that this hindrance is due to the human brain’s inability to process superfluous amounts of data. CLT classifies this data into three cognitive load types — intrinsic, extraneous, and germane — that each can help gauge complex procedures. In this research paper, a novel program call graph is presented accounting for these CLT principles. The goal of this graphical view is to reduce the cognitive load tied to the depiction of binary information and to enhance the overall binary analysis process. This feature was implemented within the binary analysis tool, angr and it’s user interface counterpart, angr-management. Additionally, this paper will examine a conducted user study to quantitatively and qualitatively evaluate the effectiveness of the newly proposed proximity view (PV). The user study includes a binary challenge solving portion measured by defined metrics and a survey phase to receive direct participant feedback regarding the view. The results from this study show statistically significant evidence that PV aids in challenge solving and improves the overall understanding binaries. The results also signify that this improvement comes with the cost of time. The survey section of the user study further indicates that users find PV beneficial to the reverse engineering process, but additional information needs to be included in future developments.
