TL;DR
Malware classification must handle organized evasion and vast volumes of polymorphic files. This paper describes the Microsoft dataset and compares publications using it, finding a growing benchmark and outlining potential research directions.
Problem
Malware analysis must process vast numbers of polymorphic files that can represent the same family and behavior in many modified forms.
Method
The paper describes the dataset and compares the main contributions of publications citing or evaluating it.
Results
More than 50 research papers and thesis works cited the challenge and dataset, including conceptual discussions and partial or complete evaluations.
Takeaways & Limitations
The comparison supports understanding existing contributions and identifying potential research directions for work using the dataset.
Abstract
from arXiv · showhide
The Microsoft Malware Classification Challenge was announced in 2015 along with a publication of a huge dataset of nearly 0.5 terabytes, consisting of disassembly and bytecode of more than 20K malware samples. Apart from serving in the Kaggle competition, the dataset has become a standard benchmark for research on modeling malware behaviour. To date, the dataset has been cited in more than 50 research papers. Here we provide a high-level comparison of the publications citing the dataset. The comparison simplifies finding potential research directions in this field and future performance evaluation of the dataset.
1 Introduction
The paper frames malware classification as a response to organized, evasive malware and the enormous volume of polymorphic files requiring analysis. It presents family identification and the Microsoft dataset as resources for addressing this challenge.
- Well-funded malware syndicates invest in technologies that evade traditional protection, causing significant financial losses to computer-system users.
- Microsoft’s realtime anti-malware products run on over 600M computers, generating tens of millions of daily data points for analysis.
- Polymorphism modifies or obfuscates files within the same malware family, making similar malicious behavior appear as many distinct files.
- Grouping files into malware families is presented as a first step toward classification and detecting new malicious files by family.
- Microsoft provided an unusually large malware dataset to support research on grouping malware variants into their respective families.
2 Dataset
The dataset is an almost half-terabyte collection of known malware from nine families, combining labeled files, headerless hexadecimal binary content, and IDA-generated metadata.
- The dataset is almost half a terabyte uncompressed and contains known malware representing 9 different families.
- Each file has an identifier, a unique 20-character hash, and an integer class label corresponding to one of the 9 malware families.
- Raw file data contains hexadecimal representations of binary content without headers, while a metadata manifest records information such as function calls and strings.
- The metadata manifest was generated using the IDA disassembler tool.
3 Citations Comparison
More than 50 papers and theses cited the challenge or dataset, spanning conceptual references and studies that evaluated proposed methods on the dataset.
