CURRENT ACTIVITIES

Multiple Software Supply Chain Attacks Targeting Open-Source Packages and Developer Tools

Indian – Computer Emergency Response Team (https://www.cert-in.org.in)

Multiple software supply chain compromises were reported in March 2026 affecting widely used developer tools and libraries across npm, PyPI, GitHub Actions, and container registries, including components associated with Checkmarx, Trivy, LiteLLM, Axios, Telnyx, and multiple npm packages linked to the CanisterWorm campaign.

Threat actors leveraged compromised credentials and unauthorized access to publishing mechanisms to introduce malicious code into trusted software packages, CI/CD workflows, and development tools. These malicious components were distributed through legitimate repositories and executed automatically via mechanisms such as postinstall scripts, import-time execution, and CI/CD pipeline execution. The malicious payloads were observed to perform credential harvesting, data exfiltration, remote payload execution, and persistence establishment within developer systems and associated environments.

Organizations and individuals using the affected tools are advised to review their environments and take appropriate mitigation actions.

Affected Products / Components:

Checkmarx GitHub Actions and OpenVSX Plugins

Affected Software: ast-github-action (v2.3.33) and kics-github-action (v2.1.20)

Malicious code introduced via unauthorized tag modifications

Risk: Exposure of CI/CD credentials and developer environment secrets

 

Trivy Vulnerability Scanner and Related Components

Affected Versions: v0.69.4, v0.69.5 and v0.69.6

Unauthorized publishing and tag manipulation using compromised credentials

Malicious activity executed within CI/CD pipelines and container images

Risk: Credential harvesting and exposure of sensitive pipeline data

 

LiteLLM (Python Package – PyPI)

Affected Versions: 1.82.7 and 1.82.8

Unauthorized PyPI package publishing using compromised maintainer access

Direct upload bypassing CI/CD workflows

Observed Capabilities:

Harvesting of environment variables and credentials

Exfiltration of collected data

 

Telnyx Python SDK (PyPI)

Affected Versions: 4.87.1 and 4.87.2

Unauthorized versions published between 03:51 UTC and 10:13 UTC on March 27, 2026

Payload execution at import time

Observed Capabilities:

Retrieval of payloads via WAV-based delivery

Credential collection and data exfiltration

 

Axios npm Library

Affected Versions: 1.14.1 and 0.30.4

Malicious dependency (plain-crypto-js) introduced into package

Execution via postinstall script

Observed Capabilities:

Deployment of cross-platform remote access trojan

System access and data exfiltration

 

Multiple Malicious npm Packages (CanisterWorm Campaign)

Execution triggered through postinstall scripts

Observed Capabilities:

Harvesting npm authentication tokens from .npmrc and environment variables

Automated republishing of compromised packages using stolen credentials

Persistence via systemd services on Linux systems

Impact:

Successful exploitation may result in:

Compromise of CI/CD pipelines

Unauthorized execution of malicious code

Theft of credentials (API keys, SSH keys, cloud tokens, Kubernetes tokens)

Unauthorized access to development environments

Data exfiltration to attacker-controlled infrastructure

Propagation of malicious packages across software supply chains

Recommendations:

Identify and remove compromised versions of affected packages

Rotate credentials (API keys, SSH keys, cloud credentials, CI/CD tokens)

Audit CI/CD workflows

Monitor for abnormal execution during installations

Enforce dependency version pinning

Limit exposure of long-lived credentials
