- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.0.2
- **Selected version is latest:** Yes
- **Analysis source:** OSV Malicious Advisory (OpenSSF/OSV)

Trusted malware advisory MAL-2026-17321 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-2026-17321 confirms this npm version as malicious. chaienv@1.0.2 is published as a small Chai environment helper, but its index.js unconditionally loads lib/config.js at require() time via \`const { config } = require('./lib/config')\`. lib/config.js is a 4,454,290-byte single-line module packed with obfuscator.io (RC4-decoded string array of roughly 26,000 entries), with no relation to the trivial no-op middleware the README advertises...

## Public findings

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

chaienv@1.0.2 is published as a small Chai environment helper, but its index.js unconditionally loads lib/config.js at require() time via \`const { config } = require('./lib/config')\`. lib/config.js is a 4,454,290-byte single-line module packed with obfuscator.io (RC4-decoded string array of roughly 26,000 entries), with no relation to the trivial no-op middleware the README advertises. The rest of lib/ ships verbatim pino internals (proto.js, multistream.js, levels.js, transport.js, worker.js, redaction.js, symbols.js) as decoys, the README CI badge and LICENSE point at github.com/pinojs/pino, and package.json bugs.url is jsonspack.com — none of which match the stated Chai-plugin purpose. Any consumer that imports this package executes the opaque 4.4MB blob on load; the package impersonates an unrelated well-known project's source tree to normalize the obfuscated sibling and bypass casual review.
