OpenSSF/OSV advisory MAL-2026-6210 confirms this npm version as malicious. @apexcraft/nano-key advertises itself as a 12-byte sortable ID generator (README and repository metadata are copied from yiwen-ai/xid-ts, an unrelated upstream project), but ships a 250KB obfuscator.io-style payload at dist/cjs/seed.cjs. package.json declares \`"postinstall": "node./dist/cjs/seed.cjs"\`, so the payload runs automatically on \`npm install\`... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. 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 @apexcraft/nano-key@1.3.8. The same advisory and Firewall decision cover these 9 recorded versions: 1.2.4, 1.2.5, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.3.7, 1.3.8. - Avoid installing @apexcraft/nano-key@1.3.8. 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% @apexcraft/nano-key advertises itself as a 12-byte sortable ID generator (README and repository metadata are copied from yiwen-ai/xid-ts, an unrelated upstream project), but ships a 250KB obfuscator.io-style payload at dist/cjs/seed.cjs. package.json declares \`"postinstall": "node./dist/cjs/seed.cjs"\`, so the payload runs automatically on \`npm install\`. The same \`runPrepare()\` entry point is also invoked at module load: index.js line 25 calls \`\_seed.runPrepare()\` inside \`newState()\`, which line 35 invokes as \`defaultState = newState()\` at top level — so any consumer that \`require\`s the package re-triggers the dropper. seed.cjs uses an RC4+base64 rotating string array decoder (\`\_0x554f\` / \`\_0x1420\`), control-flow flattening, a self-defending IIFE, and a debugger-protection loop to hide an AES-256-GCM-decrypted URL list. At runtime it \`https.request\`s those URLs, stages the response under \`~/.cache\` (or \`%LOCALAPPDATA%\` / \`~/Library/Caches\`), sha256-stamps the file, and executes it with \`child\_process.spawn(process.execPath, \[file\])\`, with an alternate \`bun\` runtime branch. There is no signature or hash pinning of the fetched bytes, the destination is decrypted at runtime (mutable C2), and the package's stated purpose (ID generation) provides no legitimate reason to fetch and execute remote code. Installing or requiring this package hands arbitrary remote code execution to whoever controls the encrypted endpoint. \#\# Source: ghsa-malware (a93a588a8c86cfaf399f05f0c68352ac421adb4cd95f3d9c4ec6d340595c6c5a) 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:** @apexcraft/nano-key - **Ecosystem:** npm - **Version:** 1.3.8 - **Version published:** 2026-06-18T08:06:45.999Z - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 9 - **Latest version:** 1.3.8 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
