relativity-foundation-corenpm
Advisory published Updated
relativity-foundation-core is a confirmed malicious npm package (MAL-2026-12426) that steals credentials and exfiltrates sensitive data (malicious version 6.8.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in relativity-foundation-core (npm)
What this malware does
package.json declares a preinstall script that runs a Node one-liner collecting os.hostname(), process.env.USER/USERNAME, cwd, npm_config_registry, CI, GITHUB_REPOSITORY, JENKINS_URL, and platform, base64-encodes the JSON blob, and issues an HTTPS GET to https://aiwi9di43fzbjwncfrimdvkgu701orcg.oastify.com/?d=<base64> on every npm install. index.js is empty, so the package's only effect is this reconnaissance beacon. The oastify.com destination is a Burp Collaborator subdomain used as an attacker-controlled out-of-band exfiltration sink.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for relativity-foundation-core (version 6.8.2).
If you installed it — respond
relativity-foundation-core 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 relativity-foundation-core 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 relativity-foundation-core-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
