Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. OpenSSF/OSV advisory MAL-2026-17624 confirms this npm version as malicious. documenclient@1.0.5 publishes an npm package whose only shipped content is a heavily obfuscated PowerShell script embedded in the README. The script hides its console window via ShowWindow(hWnd, 0), positions the window off-screen at (-32000, -32000) via SetWindowPos, sleeps a randomized interval, concatenates ~140 string fragments into a base64 blob, XOR-decodes it with key 89, and executes the resulting payload... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-10-08T04:30:05.963Z - **Finished:** 2026-10-08T04:30:05.963Z - **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 documenclient@1.0.4. - Avoid installing documenclient@1.0.4. 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% documenclient@1.0.5 publishes an npm package whose only shipped content is a heavily obfuscated PowerShell script embedded in the README. The script hides its console window via ShowWindow(hWnd, 0), positions the window off-screen at (-32000, -32000) via SetWindowPos, sleeps a randomized interval, concatenates ~140 string fragments into a base64 blob, XOR-decodes it with key 89, and executes the resulting payload via reflective \[ScriptBlock\]::Create invocation assembled from char-code type and method names. The declared main (index.js) is absent and files is empty, so the artifact has no legitimate JavaScript functionality — the dropper script is the entire payload. Console hiding, off-screen window placement, randomized sleep jitter, dynamic type/method resolution, and XOR+base64 layering have no legitimate purpose in an npm README and are canonical dropper and anti-analysis techniques. The decoded payload is not inspectable from the obfuscated form shipped, so the final behavior on a Windows host executing the script is unknown but attacker-controlled. \#\# Source: ghsa-malware (fd77316cd00f6397a05779a443f939cd3a5e09efa8321c7d52bd4623ffe2855f) 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:** documenclient - **Ecosystem:** npm - **Version:** 1.0.4 - **Version published:** 2026-10-03T13:14:09.605Z - **Package first seen:** 2026-10-08T04:30:05.963Z - **Package last seen:** 2026-10-08T04:30:05.963Z - **Known versions:** 2 - **Latest version:** 1.0.5 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]()
