The Intercom TypeScript Library version 7.0.4 has been compromised with malicious code that harvests GitHub credentials. Upon installation, the package executes a preinstall hook that downloads the Bun runtime, then runs a payload to extract GitHub credentials using the gh auth token command. The attack employs sophisticated C2 communication by querying GitHub's commit search API for specific strings embedded in public repositories, effectively using legitimate services to evade detection. The attack patterns mirror previous Shai-Hulud compromises, which exhibit worm-like behavior by automatically using stolen credentials to infect additional npm packages. With 361,510 weekly downloads, this compromise poses significant risk for a widespread infection wave similar to November 2025 when over 1,000 packages were affected.

A malicious artifact of the widely-used intercom/intercom-php package version 5.0.2 was discovered on Packagist, representing an expansion of the Mini Shai-Hulud supply chain attack from npm into the PHP ecosystem. The compromised package exploits Composer plugin execution to download Bun runtime and execute an obfuscated credential-stealing payload during installation. The malicious code harvests sensitive credentials including GitHub tokens, cloud provider credentials, SSH keys, Kubernetes tokens, and HashiCorp Vault secrets from developer machines and CI/CD environments. Stolen data is encrypted using AES-256-GCM and exfiltrated to attacker-controlled infrastructure. The payload also contains propagation logic to modify GitHub repositories and npm packages using stolen credentials. With approximately 12,700 daily installs, the compromised artifact potentially reached numerous high-value development environments before removal.
