new-soltnpm
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
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for new-solt (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging new-solt across your stack and pipelines.
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 ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks new-solt before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
