Malicious package

@cryptosrvc/shift-sdk-v4npm

Advisory published Updated

@cryptosrvc/shift-sdk-v4 is a confirmed malicious npm package (MAL-2026-12317) that steals credentials and exfiltrates sensitive data (malicious version 1.0.77). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in @cryptosrvc/shift-sdk-v4 (npm)

MAL-2026-12317
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @cryptosrvc/shift-sdk-v4

What this malware does

package.json declares a postinstall script node dist/recon.js || true that runs automatically on npm install. dist/recon.js collects installer host identity (hostname, username, SUDO_USER, homedir, cwd, platform/arch/release, node version), all internal and external IPv4 addresses from every network interface, the DNS domain via dnsdomainname, CI-provider indicators, and the full list of process.env variable names with a subset matching AWS|NPM|TOKEN|SECRET|KEY|GITHUB|SSH flagged as secret-shaped. The data is POSTed as JSON over plain HTTP to the hardcoded bare IP http://138.68.108.20:80/cb with a 4-second timeout and errors silently swallowed to preserve install success. A source comment frames the behavior as 'NON-SENSITIVE telemetry only', contradicting the actual enumeration of sudo user, network topology, and env-var names. The destination is an unattributed DigitalOcean IP with no relationship to any legitimate SDK publisher.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for @cryptosrvc/shift-sdk-v4 (version 1.0.77).

  2. If you installed it — respond

    @cryptosrvc/shift-sdk-v4 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.

  3. Did it already run?

    If @cryptosrvc/shift-sdk-v4 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.

Frequently asked questions

No. @cryptosrvc/shift-sdk-v4 on npm has been identified as a malicious package (version 1.0.77 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
