@databus-service-ui/scroll-up-contentnpm
Advisory published Updated
@databus-service-ui/scroll-up-content is a confirmed malicious npm package (MAL-2026-4378) that steals credentials and exfiltrates sensitive data (malicious version 9.9.10). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @databus-service-ui/scroll-up-content (npm)
What this malware does
scripts/postinstall.js performs two independent attacker-benefit actions when npm install runs. First, it scrapes installer-side secrets — environment variables matching npm_token, github_token, aws_access_key_id, aws_secret_access_key, aws_session_token, node_auth_token, npm_config__auth, artifactory_token, nexus_token — plus the contents of ~/.npmrc, /etc/npmrc, cwd/.npmrc, and../.npmrc, along with hostname, user, CI flags, and PATH, and POSTs the bundle to https://oob.moika.tech/report with an X-Secret header. Second, it fetches a per-OS payload from https://oob.moika.tech/payload/{linux|mac|win} with no pinning and no hash verification, writes it to the OS temp directory as._databus-service-ui_init.sh /.bat, chmods 0755, and spawns it via /bin/sh or cmd.exe in a detached, stdio-ignored process. The package scope (@databus-service-ui) uses a placeholder corporate domain with no public footprint, consistent with a dependency-confusion lure targeting a private internal name. Source comments self-label the file as [PoC] Dependency confusion payload — AUTHORIZED TESTING ONLY and tag reports with poc: 'dependency-confusion-npm', but the runtime behavior is indistinguishable from a real attack — any installer that resolves this name from the public registry has its CI/developer credentials exfiltrated and an attacker-controlled binary executed, regardless of the author's stated intent.
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
Search your lockfiles and build artifacts for @databus-service-ui/scroll-up-content (version 9.9.10).
If you installed it — respond
@databus-service-ui/scroll-up-content 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 @databus-service-ui/scroll-up-content 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 @databus-service-ui/scroll-up-content-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
