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 name 'chai-utils-test' impersonates the popular 'chai' assertion library and ships a cloned chai source tree. The declared main (index.js) calls a top-level launcher that spawns \`node lib/chai/utils/assertion.js\` as a detached child process with \`stdio:'ignore'\` and \`child.unref()\`, so the dropper survives the parent and produces no visible output. The child uses axios to GET https://statecheck.ddns.net/api/scanner.js (a dynamic-DNS host) with a base64-encoded \`key=YWRtaW46c2VjcmV0MTIz\` query parameter (likely a server-side gate for staged payload delivery), then runs the response body via \`new Function('require', s)(require)\` — granting the attacker-served code full Node \`require()\` access. The package also pre-installs a \`global.atob\` polyfill backed by \`Buffer.from(x,'base64').toString('utf8')\` in preparation for the fetched payload. Net effect: any developer or CI job that requires/imports this package executes attacker-controlled code from a mutable remote endpoint with full Node privileges. ## 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:** chai-utils-test - **Ecosystem:** npm - **Version:** 4.5.5 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 6 - **Latest version:** 4.5.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
