Malicious package

Published to npm · OSV MAL-2026-10226

What to do

Remove @logdna-web/styles from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The @logdna-web/styles npm package is a malicious package published under a namespace mimicking a legitimate internal package scope. It contains a preinstall script that executes automatically during npm install, which collects the host's public IP and other personal identifiable information (PII) and sends it to an attacker-controlled Sentry project. The package also silently routes error reporting data from consumers to the attacker's Sentry endpoint if used without explicit configuration. This behavior is part of a dependency confusion reconnaissance campaign targeting developers searching for LogDNA packages.

Impact

Installation of this package results in exfiltration of the host machine's public IP address, hostname, OS username, and runtime environment metadata to an attacker-controlled Sentry project without user consent or disclosure. The preinstall script runs automatically during npm install, potentially before any application code, enabling early reconnaissance. Additionally, any use of the package's init() function without explicit configuration causes silent routing of error and user data to the attacker. This compromises confidentiality and privacy of the affected systems and may facilitate further targeted attacks. The package is considered fully compromising to any system where it is installed or running.

Defensive guidance

Users should immediately remove the @logdna-web/styles package version 0.8.40 from their projects. Rotate all secrets and keys stored on affected machines from a separate, uncompromised device. Review and audit dependency configurations to prevent dependency confusion attacks, including verifying package scopes and sources. Avoid installing packages from untrusted or suspicious namespaces. Monitor for any unauthorized network activity related to Sentry endpoints controlled by unknown parties.

Summary

The @logdna-web/styles package was published by an attacker impersonating the LogDNA namespace to exploit dependency confusion. It includes a preinstall hook that installs @sentry/node and runs a script to collect the installing machine's public IP (via Cloudflare's trace endpoint) and other PII, then deliberately triggers an exception to send this data to a hardcoded attacker-controlled Sentry DSN. Additionally, the package's init() function silently forwards error reports and user context to the attacker's Sentry project if no explicit DSN is provided, enabling ongoing data exfiltration. This campaign uses distinct Sentry project IDs per impersonated namespace to track successful installs per victim organization. The package version 0.8.40 is affected.
