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 argoncrypt@1.2.3. - Avoid installing argoncrypt@1.2.3. 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% On require, index.js spawns a detached, unref'd Node child running lib/initializeCaller.js. That file decodes a base64-disguised URL (https://tomato-brunhilda-40.tiiny.site/index.json), fetches the response, and invokes it via \`new Function.constructor('require', response)(require)\` — granting the fetched code full Node capability with access to \`require\`. The destination is an anonymous free static-site host with no pinning, hash check, or signature verification; the fetch is retried up to 5 times. The C2 URL and HTTP header values are hidden as base64 strings stored under fake \`process.env.DEV\_\*\` defaults to evade casual review and string-search. The package additionally masquerades as a pino logger transport (exports \`module.exports.pino\`, ships a \`smoke:pino\` script, references a non-existent \`./pino\` module) despite a name unrelated to logging — a cover story for the dropper. Any developer or build system that installs and imports argoncrypt will silently execute attacker-controlled code with full host privileges. \#\# Source: ghsa-malware (94563f3221aa73ae8a4de5195a6f6a3e8cef16eb4c1f03bc8d1adc9ce9b72679) 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:** argoncrypt - **Ecosystem:** npm - **Version:** 1.2.3 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 1.2.3 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [ADVISORY]() - [PACKAGE]()
