consumerweb-serverutilsnpm
Advisory published Updated
consumerweb-serverutils is a confirmed malicious npm package (MAL-2026-14428) that steals credentials and exfiltrates sensitive data (malicious version 3.4.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in consumerweb-serverutils (npm)
What this malware does
consumerweb-serverutils 3.4.3 runs a preinstall lifecycle script that on npm install collects the installer's username, hostname, and current working directory, walks up the directory tree to read the enclosing project's package.json (name, author, version), hex-encodes the aggregated JSON, splits it into 60-character chunks, and exfiltrates it as DNS label queries to the attacker-controlled zone o.jgl.red (observed subdomain da5u87oh92rc72pp1dngqfc6hp8gwshm6.o.jgl.red). A fallback dns.lookup using the hostname is issued on error. Use of DNS as the transport bypasses HTTP egress controls and covers the payload on the wire, and the parent-package walk enables dependency-confusion targeting of the installer's private/internal package names.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for consumerweb-serverutils (version 3.4.3).
If you installed it — respond
consumerweb-serverutils 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 consumerweb-serverutils 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 consumerweb-serverutils-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
