NPM Under Siege: Malicious Packages Harvest Data, Disrupt Systems
The NPM (Node Package Manager) repository, a critical resource for JavaScript developers, is facing a surge of malicious activity. Recent discoveries highlight the vulnerability of the platform to sophisticated attacks, ranging from data theft to system disruption. This raises serious concerns about the security of the software supply chain and the potential impact on developers and organizations.
Data-Stealing Packages: Security researchers at Socket have uncovered a campaign involving sixty malicious packages on NPM. These packages, uploaded from May 12th onward, contain a post-install script designed to collect sensitive information such as hostname, internal IP address, user home directory, current working directory, username, and system DNS servers. This data is then funneled to a Discord webhook controlled by the attackers, potentially creating a valuable map for targeted network attacks.
The attackers employed social engineering tactics, using names similar to legitimate packages like 'flipper-plugins,' 'react-xterm2,' and 'hermes-inspector-msggen' to deceive developers. While these packages were initially available on NPM with a cumulative download count of 3,000, they have since been removed. Still, the incident underscores the need for vigilance when installing dependencies.
Destructive Malware Lingers: In a separate incident, Socket revealed a destructive malware campaign involving eight malicious packages that mimicked legitimate tools. These packages targeted the React, Vue.js, Vite, Node.js, and Quill ecosystems and remained undetected for two years, amassing 6,200 downloads. The malware was designed to delete files, corrupt data, and even shut down systems.
These packages evaded detection by activating payloads based on hardcoded system dates, progressively destroying framework files, corrupting core JavaScript methods, and sabotaging browser storage mechanisms. Although some activation dates have passed, the threat remains due to the possibility of future updates re-triggering the harmful functions. Specific packages included js-bomb, js-hood, vite-plugin-bomb-extend, and others that perfectly mimicked legitimate development tools, making them difficult to detect.
Reconnaissance Campaign: A reconnaissance campaign is also active on the NPM repository, with malicious scripts downloaded over 3,000 times. These scripts exfiltrate data such as hostnames, IP addresses, DNS configurations, usernames, and project paths. The campaign utilizes install-time scripts, also known as post-install scripts, which automatically run after a npm package is installed.
Socket has identified 60 npm packages carrying these scripts, distributed under accounts like bbbb335656, cdsfdfafd1232436437, and sdsds656565. The packages, including seatable, datamart and seamless-sppmy, feature the same JavaScript logic for network and host fingerprinting, potentially creating a map of enterprise networks for future intrusions. While Socket reported these packages, the incident highlights the weaknesses in NPM's security measures.
The recurring incidents on NPM demonstrate the critical need for enhanced security measures and developer awareness. The impacts from seemingly small malicious packages are far-reaching, from data breaches to complete system compromises.
