Ten malicious versions of the npm package @7nohe/openapi-react-query-codegen were published with valid provenance attestations after a threat actor abused a comment-triggered GitHub Actions publishing workflow. The packages execute an obfuscated JavaScript loader during installation that decrypts a second-stage payload targeting cloud, package registry, and CI/CD credentials with self-propagation capabilities. The attack leverages legitimate infrastructure like GitHub for exfiltration and command retrieval, and establishes persistence via LaunchAgents, systemd services, and developer tool configuration modifications.

A new wave of the Mini Shai-Hulud/Miasma/Hades supply chain attack campaign has compromised 23 npm packages across the LeoPlatform and RStreams ecosystems, plus the Verana Blockchain Go module. The attack uses binding.gyp install-time execution (Phantom Gyp pattern) to trigger multi-stage obfuscated JavaScript loaders that decrypt AES-GCM payloads, stage execution through Bun to evade Node.js security hooks, and steal developer/CI/CD credentials including npm, GitHub, cloud, and AI-agent tokens. The campaign also poisons GitHub Actions workflows and plants persistence hooks in AI coding assistant configurations, creating delayed execution surfaces that survive package remediation.

A fast-moving supply chain campaign dubbed Mini Shai-Hulud/Miasma is targeting Python developers via malicious PyPI wheels. The threat actors are utilizing novel execution techniques, including trojanized native extensions and split-loader .pth hooks that search sys.path for payloads, to deploy the Hades stealer and harvest credentials from CI/CD pipelines and developer workstations.

Software Supply Chain and AI Exploitation Dominate Threat Landscape The software supply chain has become the primary battlefield for attackers because compromising a single developer tool can cascade into thousands of enterprise networks. Campaigns like Mini Shai-Hulud and TrapDoor are stealing credentials and injecting backdoors across major code registries, while the Laravel Lang Compromise and the Coruna Exploit Kit show how malicious code can automatically execute to steal secrets or exploit end users. As a result, organizations must treat developer environments as high-value targets, because a single compromised package or malicious VS Code extension can lead to catastrophic breaches like the GitHub internal repository theft by TeamPCP. In parallel, artificial intelligence is simultaneously accelerating attacks and creating dangerous new attack surfaces. Threat actors are using AI to automate influence campaigns like Patriot Bait and crack passwords, while also impersonating AI tools like Gemini CLI and Claude Code to deliver infostealers. Furthermore, attackers are directly targeting exposed AI infrastructure, such as Ollama AI endpoints, and manipulating AI coding assistants via hidden prompt injections in campaigns like TrapDoor, which means AI systems are both the weapon and the target. These trends together suggest that traditional perimeter defenses are failing against supply chain and AI-driven threats. Managers should immediately enforce strict vetting of open-source packages, restrict developer access to unverified extensions, and ensure AI infrastructure is not exposed to the public internet.

In response to the ongoing Mini Shai-Hulud supply chain campaign, npm has invalidated all granular access tokens that bypass two-factor authentication. The threat actors have been harvesting credentials from CI/CD environments to automate the publishing of malicious package versions, successfully bypassing existing controls like OIDC Trusted Publishing. To provide a more robust defense, npm has introduced an opt-in Staged Publishing feature that requires interactive MFA approval for automated releases.

A large-scale npm supply chain attack compromised hundreds of packages, notably within the @antv ecosystem, using a malware variant known as Mini Shai-Hulud. The malware executes upon installation to harvest sensitive developer and CI/CD secrets, exfiltrating them to a hardcoded C2 server or via a GitHub repository fallback, and leverages stolen npm tokens to propagate itself to other packages.

The TeamPCP threat actor deployed the Mini Shai-Hulud worm in a sophisticated supply chain attack targeting the npm ecosystem via a GitHub Actions CI cache-poisoning technique. The malware steals credentials, establishes persistence via developer tools like VS Code and Claude Code, and features a destructive dead man switch that wipes the victim's home directory if access tokens are revoked.

A sophisticated supply-chain worm dubbed 'Mini Shai-Hulud' has compromised numerous high-profile npm and PyPI packages, including TanStack and Mistral AI. The heavily obfuscated payload targets CI/CD environments to systematically harvest credentials from GitHub, AWS, Vault, and Kubernetes. It autonomously propagates by minting npm publish tokens and committing malicious code to repositories, while exfiltrating stolen secrets via the Session P2P network.

The release of pnpm 11 introduces significant supply chain security enhancements, including a default 24-hour minimum release age for packages, the blocking of exotic subdependencies, and a streamlined allowBuilds model. These features are designed to mitigate rapid supply chain attacks, such as the recent Mini Shai-Hulud campaign, by restricting install-time execution and unexpected dependency sources.

The Mini Shai-Hulud supply chain attack campaign has expanded into the PHP ecosystem by compromising the widely used intercom/intercom-php package on Packagist. The malicious artifact abuses Composer plugin execution to download the Bun runtime and execute an obfuscated JavaScript payload designed to harvest and exfiltrate sensitive credentials from developer environments and CI/CD pipelines.

The official intercom-client npm package (version 7.0.4) was compromised in a supply chain attack attributed to the Mini Shai-Hulud campaign and linked to the TeamPCP threat actor. The malicious package executes during installation via a preinstall hook to harvest cloud, Kubernetes, and Vault credentials from developer and CI/CD environments, exfiltrating them via the GitHub API.

The popular PyPI package 'lightning' was compromised in a supply chain attack affecting versions 2.6.2 and 2.6.3. The malicious package executes an obfuscated JavaScript payload via the Bun runtime to harvest cloud and developer credentials, poison GitHub repositories by impersonating Anthropic's Claude Code, and infect local npm packages.

The 'mini Shai-Hulud' campaign is a software supply chain attack involving compromised npm packages associated with SAP's Cloud Application Programming Model (CAP). The malicious packages execute upon installation or runtime to harvest sensitive credentials, encrypt the stolen data, and exfiltrate it via public GitHub repositories. Package maintainers have released patched versions to mitigate the threat.

AI Weaponization and Developer Supply Chain Attacks Redefine the Perimeter Attackers are aggressively targeting the software development process because compromising a single developer tool can unlock thousands of corporate networks. In parallel, artificial intelligence is collapsing the cost of attacks, allowing criminals to build convincing deepfakes and automated phishing campaigns in minutes. As a result, traditional security like multi-factor authentication is increasingly bypassed using tricks that steal active login sessions rather than passwords. These trends together suggest that relying on perimeter defenses and basic hygiene is no longer enough, as attackers hide inside trusted cloud services and legitimate software updates. This matters because organizations are losing visibility into where their sensitive data actually lives, especially as AI tools create hidden pathways into company systems. Defenders must shift their focus to monitoring user behavior after login and securing the automated systems that build their software. Watch for unusual activity in your developer tools and implement stricter checks on third-party software.
