creditgaugenpm
creditgauge is a confirmed malicious npm package (MAL-2026-10633) that steals credentials and exfiltrates sensitive data (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
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for creditgauge (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging creditgauge across your stack and pipelines.
If you installed it — respond
creditgauge is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If creditgauge was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks creditgauge before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
