Comprehensive Analysis of Malicious Open-Source Software Packages in the Wild

Core Concepts

Malicious open-source software packages play a central role in software supply chain attacks, and this study provides a comprehensive analysis of a large-scale dataset of 23,425 malicious packages from various online sources to understand their diversity, attack campaigns, and evolution.

Abstract

The paper presents a comprehensive analysis of malicious open-source software (OSS) packages, which are a key component of software supply chain (SSC) attacks. The authors first built and curated the largest dataset of 23,425 malicious packages from scattered online sources, including open-source datasets, commercial websites, social networks, and individual blogs.
The key findings include:

There is a lack of industry-wide and industry-academia collaboration, limiting the data quality of malicious packages, as there is little data overlap between different sources.
Despite the large volume of malicious packages, their diversity evolution is slow and relatively stable, suggesting that today's defense tools can detect most malicious packages due to their use of known attack behaviors.
Malicious OSS packages have a distinct life cycle of {changing→release→detection→removal}, where attackers repeatedly change the package (e.g., different name) to launch subsequent attack attempts.
While malicious packages often lack context about how and who released them, security reports reveal missing information about corresponding SSC attack campaigns.

The authors also propose a knowledge graph, MALGRAPH, to represent the relationships between malicious packages, including duplicated, dependency, similar, and co-existing relationships. MALGRAPH is used to analyze the diversity, attack campaigns, and evolution of malicious packages.

Stats

The dataset contains 23,425 malicious packages, of which 9,141 are available and 14,589 are unavailable (only package names/versions are known).

Quotes

"Malicious packages initially deceive developers and users to download and install them and then execute subsequent behaviors, such as implanting backdoors [2], stealing sensitive information [3], and downloading and executing payloads without user permission (e.g., cryptominers [4])."
"Despite an increasing number of OSS malicious packages, their diversity evolution is slow and relatively stable. This suggests that today's defense tools work well because malicious packages use old and known attack behaviors."
"OSS malicious package has its distinct life cycle, denoted as {changing→release→detection→removal}. An SSC attack campaign is a repeating process in which attackers change malicious packages to launch several attack attempts."

Deeper Inquiries

How can industry-wide and industry-academia collaboration be improved to enhance the quality and diversity of malicious package datasets?

In order to enhance the quality and diversity of malicious package datasets, industry-wide and industry-academia collaboration can be improved through several key strategies:

Establishing Formal Partnerships: Creating formal partnerships between industry organizations and academic institutions can facilitate the sharing of expertise, resources, and data. This collaboration can lead to a more comprehensive understanding of emerging threats and the development of more effective defense mechanisms.

Joint Research Projects: Collaborating on joint research projects focused on malware analysis and detection can help bridge the gap between academia and industry. By working together, researchers can leverage academic insights and industry experience to create innovative solutions.

Data Sharing Agreements: Establishing data sharing agreements that outline the terms and conditions for sharing malicious package datasets can promote transparency and collaboration. This can help address the issue of dataset redundancy and improve the overall quality of the datasets.

Cross-Training Programs: Implementing cross-training programs where industry professionals and academic researchers can exchange knowledge and skills can foster a better understanding of each other's perspectives and approaches. This can lead to more effective collaboration on malware research.

Regular Workshops and Conferences: Organizing regular workshops and conferences that bring together industry experts and academic researchers in the field of cybersecurity can facilitate networking, knowledge sharing, and collaboration on cutting-edge research topics.

By implementing these collaborative strategies, industry-wide and industry-academia collaboration can be enhanced to improve the quality and diversity of malicious package datasets.

How can the context and provenance of malicious packages be better captured to understand the motivations and tactics of attackers in software supply chain attacks?

Capturing the context and provenance of malicious packages is crucial for understanding the motivations and tactics of attackers in software supply chain attacks. Here are some ways to better capture this information:

Security Analysis Reports: Encouraging security researchers and organizations to publish detailed security analysis reports about malicious packages can provide valuable context about the attack campaigns, including the tactics used, the motivations behind the attacks, and the impact on users.

Metadata Collection: Collecting metadata associated with malicious packages, such as timestamps, version history, and dependencies, can help establish the provenance of the packages and track their evolution over time. This information can shed light on the attackers' strategies and behaviors.

Knowledge Graph Representation: Utilizing knowledge graphs to represent the relationships between malicious packages, attackers, and attack campaigns can provide a visual and structured way to capture the context and provenance of the packages. This can help in identifying patterns and connections between different malicious activities.

Collaborative Threat Intelligence Sharing: Establishing platforms for collaborative threat intelligence sharing among security professionals, researchers, and organizations can facilitate the exchange of information about malicious packages and associated attack campaigns. This shared knowledge can enhance the understanding of attackers' motivations and tactics.

Incident Response Data: Leveraging incident response data from past attacks can offer insights into the context of malicious packages, including the methods used by attackers, the vulnerabilities exploited, and the impact on systems. Analyzing this data can help in building a comprehensive picture of the attackers' motivations and tactics.

By implementing these strategies to capture the context and provenance of malicious packages, cybersecurity professionals can gain a deeper understanding of attackers' behaviors and motives in software supply chain attacks.
