@cryptosrvc/no-brainer-sdknpm
Advisory published Updated
@cryptosrvc/no-brainer-sdk is a confirmed malicious npm package (MAL-2026-12315) that steals credentials and exfiltrates sensitive data (malicious version 1.0.18). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @cryptosrvc/no-brainer-sdk (npm)
What this malware does
On npm install, the package's postinstall script (dist/recon.js) collects installer-side host reconnaissance — hostname, username, SUDO_USER, home directory, cwd, network interfaces including internal IPs, DNS domain via dnsdomainname, and npm lifecycle context — and enumerates process.env, filtering the key names against a regex targeting AWS, GCP, AZURE, NPM, NODE_AUTH, DOCKER, KUBE, VAULT, TOKEN, SECRET, KEY, PASS, CRED, GITHUB, GITLAB, and SSH. Both the full env-name list and the credential-shaped subset are serialized and POSTed as JSON over plain HTTP to hardcoded bare IP 138.68.108.20:80/cb, with a npm-install-telemetry/1.0 User-Agent and an inline comment framing the payload as 'NON-SENSITIVE telemetry only' despite including sudo_user, internal network layout, and credential env-var name inventory. Behavior fires automatically as a postinstall lifecycle hook.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @cryptosrvc/no-brainer-sdk (version 1.0.18).
If you installed it — respond
@cryptosrvc/no-brainer-sdk 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 @cryptosrvc/no-brainer-sdk 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 @cryptosrvc/no-brainer-sdk-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
