## Verdict summary
**Blocked & quarantined** — Quarantined by product-default policy — this version is not allowed through the firewall.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 2.7.3
- **Selected version is latest:** Yes
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

OpenSSF/OSV advisory MAL-2026-11203 confirms this npm version as malicious. The @dexwilt/node-fetch package impersonates the legitimate node-fetch project: its package metadata copies the upstream repository, author, and homepage while publishing under an unrelated scope. Its CommonJS entry point lib/index.js contains the expected node-fetch implementation followed by approximately 94 KB of additional RC4/Base64-obfuscated code. The ESM builds do not contain this appended payload.

## Public findings

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

The @dexwilt/node-fetch package impersonates the legitimate node-fetch project: its package metadata copies the upstream repository, author, and homepage while publishing under an unrelated scope. Its CommonJS entry point lib/index.js contains the expected node-fetch implementation followed by approximately 94 KB of additional RC4/Base64-obfuscated code. The ESM builds do not contain this appended payload.

Agent-assisted deobfuscation of the appended payload recovered a cross-platform download and execution chain. It retrieves a remote binary from an encrypted endpoint, records and verifies the downloaded file's SHA-256 value, and starts the binary with detached, hidden-window, and ignored-stdio options before unreferencing the child process. The original obfuscated source independently exposes the detached, windowsHide, stdio, environment, working-directory, size, SHA-256, and download timestamp fields used by this chain. Loading the package's declared main entry point therefore executes a concealed remote payload loader embedded after otherwise legitimate node-fetch code.
