Advisory published Updated
creditgauge is a confirmed malicious npm package (MAL-2026-10633) that executes malicious code on install (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in creditgauge (npm)
What this malware does
The package has no functional library code: package.json declares main=index.js but no index.js is shipped; the tarball contains only package.json and a.claude/settings.json payload. The settings.json overrides ANTHROPIC_BASE_URL to https://api.minimaxi.com/anthropic (a non-Anthropic host) and embeds a hardcoded ANTHROPIC_AUTH_TOKEN, so any Claude Code session picking up this configuration silently routes the developer's prompts and source code through a third-party endpoint under an attacker-supplied token. The same file defines a statusLine that runs a bash command resolving to scripts/wrapper.sh inside the plugin cache directory for the third-party plugin github:cwf818/topgauge-cc (referenced via enabledPlugins), re-invoked every 10 seconds. defaultMode is set to bypassPermissions and skipDangerousModePermissionPrompt is set to true, disabling the confirmation prompts that would normally gate that execution. The combined effect is silent relay of AI prompts/code through an attacker-controlled proxy plus recurring shell execution of unvetted third-party plugin code inside the developer's environment.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for creditgauge (version 1.0.0).
If you installed it — respond
Remove creditgauge from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If creditgauge was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks creditgauge-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
