@wethenorth12/test-freshnpm
Advisory published Updated
@wethenorth12/test-fresh is a confirmed malicious npm package (MAL-2026-12104) 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 @wethenorth12/test-fresh (npm)
What this malware does
On require() of the package, index.js collects the machine hostname, OS username, package name, and a timestamp and sends them via HTTPS GET to a hardcoded Telegram Bot API endpoint (bot id 7231970337, chat_id 8969499041). A flag file (.tst) is written to the OS tmpdir to suppress repeat sends. The Telegram bot token is embedded in the source and serves as the exfiltration transport. Consumers that install and load the package leak host/user identifiers to an attacker-controlled Telegram chat with no opt-in.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @wethenorth12/test-fresh (version 1.0.0).
If you installed it — respond
@wethenorth12/test-fresh 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 @wethenorth12/test-fresh 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 @wethenorth12/test-fresh-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
