dotishnpm
Advisory published Updated
dotish is a confirmed malicious npm package (MAL-2026-14418) 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 dotish (npm)
What this malware does
The package's postinstall lifecycle script auto-runs on npm install and reads the installer's current working directory .env file (typically containing API keys, database credentials, and cloud tokens), then POSTs the full file contents together with os.hostname() to a hardcoded Telegram Bot API endpoint. The destination URL is stored as a base64 literal and decoded at runtime to https://api.telegram.org/bot<redacted>/sendMessage (bot id 8406833247, chat id 5934680334). Variable names are shaped to obscure the network call, comments are written in Somali, and the outbound request is wrapped in a try/catch that swallows errors. The package presents itself as an env-var utility and does not disclose any of this behavior.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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