Malicious Packages Hidden in NPM

Affected platforms: All platforms where NPM packages can be installed
Impacted parties: Any individuals or institutions that have these malicious packages installed
Impact: Leak of credentials, sensitive information, source code, etc.
Severity level: High

Over the past few months, the FortiGuard Labs team has discovered several malicious packages hidden in NPM (Node Package Manager), the largest software registry for the JavaScript programming language. These packages were found through a system dedicated to discover malicious open-source packages from various ecosystems e.g. PyPI, NPM. In this blog, we will look at some of these packages, grouping them based on similar styles of code or functions.

In general, most of these malicious packages use install scripts that run pre or post-install. Whenever an NPM package is installed, those scripts are run as well. An example of this is shown below.

Every package we found aims to steal sensitive data, such as system or user information, via a webhook or file-sharing link. Let’s explore the sets of packages below.

The First Set:

  • @expue/webpack (version 0.0.3-alpha.0)
  • @expue/core (version 0.0.3-alpha.0)
  • @expue/vue3-renderer (version 0.0.3-alpha.0)
  • @fixedwidthtable/fixedwidthtable (version 0.0.2)
  • @virtualsearchtable/virtualsearchtable (version 0.1.1)

This first set shows an obfuscated index.js script. However, we can identify some clues in the strings that may raise suspicions. Let’s try to simplify this code.

After cleaning up the script, we can see it exfiltrates sensitive data, including Kubernetes configurations, SSH keys, and other critical information. It also gathers basic system fingerprinting details, like username, IP address, and hostname, without any prior warning.

The Second Set:

  • binarium-crm (versions 1.0.0, 1.0.9, 1.9.9)
  • career-service-client-0.1.6 (versions 0.1.6, 0.1.13, 0.1.15)
  • hh-dep-monitoring (versions 0.1.5, 0.1.14)
  • orbitplate (versions 1.0.4, 1.0.6)

The index.js in this second set of packages sends an HTTP GET request to a specific URL, including query parameters. It scans for particular files and directories that may contain sensitive information. This script also enables the unauthorized extraction of critical developer data, including source code and configuration files. The targeted files and directories may contain highly valuable intellectual property and sensitive information, such as various application and service credentials. It then archives these files and directories and uploads the resulting archives to an FTP server.

The Third Set:

  • @zola-helpers/client (versions 1.0.1, 1.0.2, 1.0.3)
  • suncorp-styleguide-base (versions 1.0.3, 1.0.4, 1.0.5)

In this set, the index.mjs install script uses a Discord webhook to exfiltrate sensitive data, such as system information, username, and folder contents.

The Fourth Set:

  • @next-translate-root/i18n (versions 1.0.1, 1.0.2)
  • @ag-grid-react/lib (version 1.0.1)
  • @next-translate-root/locales (versions 1.0.0, 1.0.1, 1.0.2)

As with the third set, this fourth set also uses an index.mjs install script and a Discord webhook to exfiltrate sensitive data. But this time, they use an alternate style of coding.

The Fifth Set:

  • @dtx-company/flowcode-generator-types (version 200000.0.2)

This fifth set uses an index.js install script to exfiltrate host and username info and home users’ home directory contents via a webhook.

The Sixth Set:

  • squarespace-abtest (version 1.0.1)
  • ruamel.taml.clib (version 0.1.2)
  • regily (version 1.0.0)  
  • developer-scaffold-full-width-wrapper (versions 1.9.9, 21.0.9)
  • @abb-americas/angular-utilities (version 1.0.0)
  • @abb-americas/image-scaler (version 1.0.0)
  • @abdulmz/mz-test (version 1.1.1)
  • @ikea-aoa/component-financial-services (version 99.0.1)
  • @ikea-aoa/component-lightbox (version 99.0.1)
  • @ikea-aoa/component-popover (version 99.0.0)

This set—the most commonly found style—uses yet another index.js install script to exfiltrate information.

The Seventh Set:

  • @cima/prism-utils (versions 23.2.1, 23.2.2)

In this set, the packages use an installer.js install script to carry out the attack, similar to the previous two, but we can see that the environment variable ‘NODE_TLS_REJECT_UNAUTHORIZED’ is set to ‘0’. This disables TLS certificate validation, which may make the connection insecure and vulnerable to man-in-the-middle attacks.

The Eighth Set:

  • discorddd.jss (versions 1.4.9, 1.5.0, 1.6.4)
  • saaaaaaaaaaaaaaaaaaaaaaa (version 1.4.1)

This package automatically downloads and executes a potentially malicious executable file from a URL to a C:/ directory.

The Ninth Set:

  • evernote-thrift (version 1.9.99)
  • en-features-rollout (version 1.90.9)
  • en-conduit-electron (version 1.90.9)
  • en-conduit-electron-auth (version 1.90.9)
  • en-conduit-electron-worker (version1.90.9)
  • en-thrift-internal (version 2.30.9)
  • en-conduit-electron-renderer (version 1.90.9)

This package uses another script style to gather system information, including the victim’s public IP address and then exfiltrates this information to a discord webhook.

Conclusion

This blog groups together a collection of malicious NPM packages that use install scripts to steal users’ sensitive info based on styles of code or functions. End users should watch for packages that employ suspicious install scripts and exercise caution. We will continue hunting for and reporting malicious packages to help users avoid becoming victims.
