The research area of this study is artificial intelligence (AI) and machine learning, specifically focusing on neural networks capable of understanding binary code. The goal is to automate reverse engineering processes by training AI to understand binaries and provide descriptions in English. This is important because binaries can be difficult to understand due to their complexity and lack of transparency. Malware analysis and reverse engineering tasks are particularly demanding, and the scarcity of experienced professionals further accentuates the need for effective automated solutions.
The research addresses an important problem: understanding what binary code does is difficult because it requires specialized skills and knowledge. Often, reverse engineers must dig deeper into the code to discern its functionality. The research team aimed to simplify this process by creating an automated tool to analyze code and generate meaningful descriptions in English, helping security experts understand software, whether malicious or harmless. This tool could save time and provide clarity when traditional methods run into difficulties.
Current approaches involve extended language models (LLMs) and datasets that relate code to English descriptions. However, the datasets used have notable shortcomings, such as insufficient samples, vague descriptions, or a focus on interpreted languages rather than compiled languages. For example, datasets like XLCoST and GitHub-Code have limitations in providing accurate code descriptions. In contrast, others like Deepcom-Java and CoNaLa do not cover widely used compiled languages like C and C++.
Researchers from MIT Lincoln Laboratory, Lexington, MA, USA, presented a new dataset from Stack Overflow, one of the largest online programming communities. With over 1.1 million entries, this dataset was intended to better translate binaries into English descriptions. The team designed a method to extract data from this vast resource, transforming it into a structured dataset combining binaries with textual descriptions. This dataset has become a substantial source of information for training machine learning models.
The researchers' approach was to analyze Stack Overflow pages labeled as C or C++ and convert them into code snippets. These snippets contained code and textual explanations, which were processed to extract the most relevant information. The team then generated compileable binaries from this data and compared them to the appropriate textual explanations, creating a dataset of 73,209 valid samples. This dataset allowed them to train neural networks to understand binary code more efficiently.
The team developed a new methodology called Embedding Distance Correlation (EDC) to evaluate their dataset. To determine the quality of the dataset, they aimed to measure the correlation between binary samples and their associated English descriptions. Unfortunately, their results indicated a weak correlation between binary code and textual descriptions, similar to other datasets. The team's method highlighted that their dataset was insufficient to effectively train a model because the correlation between code and explanations was too low to provide reliable results.

In conclusion, the study reveals the complexity of developing high-quality datasets that adequately train machine learning models to summarize code. Despite the considerable effort required to create a dataset from over 1.1 million entries, the results suggest that improved data augmentation and evaluation techniques are still needed. The researchers highlighted the challenges of creating datasets that can sufficiently capture the nuances of binary code and translate them into meaningful descriptions, indicating that further research and innovation is needed in this area.
