relativity-foundation-corenpm
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
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for relativity-foundation-core (version 6.8.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging relativity-foundation-core across your stack and pipelines.
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 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 relativity-foundation-core 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.

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.
