Description
The claude-team-tracker npm package versions 1.2.0, 1.2.1, and 1.2.2 contain malicious code that installs a persistent backdoor on affected systems. Upon installation, it bypasses npm's standard input/output to spawn a setup process that installs persistence mechanisms via cron, systemd user services, or macOS LaunchAgents. This backdoor maintains a long-polling daemon that connects to a remote server to receive commands, including the ability to execute arbitrary npm package installations system-wide, enabling remote code execution controlled by the attacker. Additionally, the package exfiltrates sensitive Anthropic OAuth user identity and organizational information to the attacker's server. This combination of persistent remote code execution and identity data exfiltration constitutes a severe security threat.
