new-soltnpm
Advisory published Updated
new-solt is a confirmed malicious npm package (MAL-2026-6285) that steals credentials and exfiltrates sensitive data (malicious versions 0.0.7, 0.0.8, 0.0.9). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in new-solt (npm)
What this malware does
Package [email protected] contains index.js which imports child_process and invokes execSync with bash and zsh shell strings (around lines 315 and 331). Without further code-flow tracing it cannot be determined whether these shell calls are tied to install-time or import-time side effects, whether they execute attacker-controlled or fetched content, or whether they form part of a documented user-facing CLI. The pattern alone (child_process + shell execution) is consistent with both legitimate tooling and exfiltration/dropper behavior, so a human reviewer should examine the full execution path before installing or recommending this package.
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 new-solt (3 malicious versions).
If you installed it — respond
new-solt 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 new-solt 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 new-solt-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
