@onum-releases/shared-componentsnpm
Advisory published Updated
@onum-releases/shared-components is a confirmed malicious npm package (MAL-2026-6126) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.1, 1.0.2, 1.0.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @onum-releases/shared-components (npm)
What this malware does
On require()/import, index.js reads os.hostname() and issues an HTTP GET to 'shared-components.<hostname>.200majoeu01dk02xnjdajro1isojc90y.oastify.com/shared-components', leaking the installer's hostname out-of-band to an attacker-controlled Burp Collaborator subdomain. The package.json describes the package as a 'Security PoC placeholder - benign, no runtime payload' but the shipped index.js contradicts that claim and actively beacons on every load. The @onum-releases scope combined with the generic 'shared-components' name is consistent with a dependency-confusion squat against an internal Onum private package; any build that resolves this public version executes the beacon and discloses the host identifier to a third party. Self-described 'PoC' framing does not neutralize the harm — the code performs real installer-side data exfiltration.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for @onum-releases/shared-components (3 malicious versions).
If you installed it — respond
@onum-releases/shared-components 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 @onum-releases/shared-components 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 @onum-releases/shared-components-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
