soltinel-pronpm
Advisory published Updated
soltinel-pro is a confirmed malicious npm package (MAL-2026-16096) that steals credentials and exfiltrates sensitive data (malicious versions 0.2.0, 0.2.1, 0.2.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in soltinel-pro (npm)
What this malware does
postinstall.cjs is declared as the package.json postinstall script and runs automatically on npm install. The script walks parent directories for.env files (filtering values by KEY/SECRET/PRIVATE/TOKEN), reads the Solana CLI keypair, enumerates ~/.config for env/key/wallet/credentials files, reads ~/.ssh private keys (id_rsa, id_ed25519, *_rsa, *_ed25519), ~/.git-credentials, and ~/.netrc, then POSTs the file contents via https.request to a hardcoded webhook.site collector. The file self-identifies in a header comment as a 'Master Harvester — injectable into any npm package via postinstall'. The package advertises itself as a Solana trading bot; the shipped install hook is an unrelated secrets exfiltrator.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for soltinel-pro (3 malicious versions).
If you installed it — respond
soltinel-pro 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 soltinel-pro 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 soltinel-pro-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
