Trusted malware advisory MAL-2026-17228 identifies this version as malicious. 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-2026-17228 confirms this npm version as malicious. The package's \`preinstall.js\` contains a base64+zlib-encoded 257 KB Windows PE executable. On \`npm install\` on Windows, the script decodes the blob and writes it to \`%LOCALAPPDATA%\\Microsoft\\Conhost\\conhost.exe\` — a path and filename that impersonates a legitimate Windows console host binary — then spawns it via \`child\_process.spawn\` with \`detached: true\`, \`stdio: 'ignore'\`, and \`windowsHide: true\`, so execution is...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package's \`preinstall.js\` contains a base64+zlib-encoded 257 KB Windows PE executable. On \`npm install\` on Windows, the script decodes the blob and writes it to \`%LOCALAPPDATA%\\Microsoft\\Conhost\\conhost.exe\` — a path and filename that impersonates a legitimate Windows console host binary — then spawns it via \`child\_process.spawn\` with \`detached: true\`, \`stdio: 'ignore'\`, and \`windowsHide: true\`, so execution is silent and survives the npm process. The decoded PE contains a section named \`.kntrat\` and references the external host \`65.87.7.132\` and the repository \`github.com/syskiel/kntrat-e\`, indicating remote command-and-control functionality (RAT-shaped naming). The package has no legitimate SDK functionality visible; the preinstall hook exists solely to stage and run the embedded executable. Installing this package on a Windows host results in full arbitrary code execution under the installing user, with a masqueraded persistent binary staged under LOCALAPPDATA and a C2 endpoint reachable at 65.87.7.132.
