A sophisticated supply chain attack infiltrated PyPI’s software repository, leveraging AI chatbot wrappers as a lure to distribute JarkaStealer malware. For nearly a year, malicious Python packages disguised as legitimate integrations for ChatGPT and Claude AI provided real chatbot functionality while covertly stealing browser data, session tokens, and system information. This attack highlights the ongoing risks within open-source ecosystems and the growing use of AI-themed malware to deceive developers and users alike.
Off-Roading Malware
Unlike targeted cyber campaigns, this attack was geographically widespread, impacting individual users across 30+ countries, with high infection rates in France, Germany, the US, China, and Russia. The malicious packages accumulated over 1,700 downloads, exposing victims to a stealer malware capable of extracting credentials from Telegram, Discord, Steam, and even a Minecraft cheat client. Additionally, JarkaStealer forcibly closed Chrome and Edge browsers to steal stored login credentials before transmitting the data to attacker-controlled servers. The scale of the attack demonstrates the vulnerabilities inherent in open-source package repositories and the difficulty of detecting sophisticated supply chain threats before they spread widely.
MOD (Malware on Demand)
Investigations by Kaspersky’s Global Research & Analysis Team (GReAT) revealed that JarkaStealer operates under a Malware-as-a-Service (MaaS) model, making it accessible to a wide range of cybercriminals. The malware is sold on Telegram channels and underground bot markets, allowing attackers to deploy their own stealer campaigns with minimal effort. Furthermore, the leak of JarkaStealer’s source code on GitHub has expanded its reach, making its integration into new attack campaigns highly probable. Linguistic analysis of the malware’s code and sales advertisements suggests that its developer is Russian-speaking, though attribution remains uncertain. The widespread availability of JarkaStealer on underground forums highlights the increasing ease with which cybercriminals can access and deploy sophisticated malware without requiring advanced technical skills.
S for Security, and Supply Chain
Although the malicious packages have been removed from PyPI, this attack underscores the persistent vulnerabilities within open-source software ecosystems. Developers and organizations must implement proactive security measures to prevent similar incidents:
- Verify the legitimacy of dependencies by auditing package maintainers, checking official repositories, and ensuring that no unexpected updates have been pushed.
- Implement rigorous integrity verification methods such as cryptographic signing and checksums to confirm that installed packages have not been tampered with.
- Monitor for abnormal package behaviors by analyzing network activity, system resource usage, and unexpected file modifications after installation.
- Limit permissions for installed packages to restrict their access to sensitive system functions and prevent unauthorized data collection.
- Utilize automated security tools designed to scan repositories like PyPI for signs of malicious code or unauthorized modifications.
- Educate development teams about the risks of supply chain attacks and provide guidelines on best practices for securing software dependencies.
As cyber threats become more innovative and deceptive, proactive measures are essential to safeguard open-source repositories and prevent further compromise. The JarkaStealer campaign is a stark reminder that malware can lurk within trusted environments, reinforcing the need for vigilance and enhanced security across all software supply chains. Open-source ecosystems are an invaluable resource for developers worldwide, but without strong security protocols, they can also become prime targets for cybercriminals seeking to exploit trust and automation in software distribution.
