OpenSSF/OSV advisory MAL-2026-3765 confirms this npm version as malicious. The package declares a postinstall hook (\`"postinstall": "node postinstall.js"\` in package.json) that runs unconditionally on \`npm install\`. The script's own header calls itself a "Token harvester + Crypto wallet scanner / Runs on npm install. Silent. Zero trace." It performs two distinct credential-theft behaviors: ## 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 joi-pack@1.0.5. The same advisory and Firewall decision cover these 3 recorded versions: 1.0.3, 1.0.4, 1.0.5. - Avoid installing joi-pack@1.0.5. 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% The package declares a postinstall hook (\`"postinstall": "node postinstall.js"\` in package.json) that runs unconditionally on \`npm install\`. The script's own header calls itself a "Token harvester + Crypto wallet scanner / Runs on npm install. Silent. Zero trace." It performs two distinct credential-theft behaviors: 1) Installer secret harvest: reads \`~/.npmrc\`, \`~/.env\`, and \`~/.git-credentials\`; extracts npm auth tokens (regex \`npm\_\[a-zA-Z0-9\]{36}\`), API keys, database URLs, cloud credentials, EVM private keys (\`0x\[a-fA-F0-9\]{64}\`), and git credentials; POSTs the JSON result to the hardcoded bare-IP endpoint \`http://149.28.127.35:8888\` over plain HTTP (configurable only via \`C2\_URL\` env). 2) Crypto wallet stealer: enumerates 71 hardcoded Chrome/Brave/Edge/Firefox wallet extension IDs (MetaMask \`nkbihfbeogaeaoehlefnkodbefgpgknn\`, Phantom \`bfnaelmomeimhlpmgjnjophhpkkoljpa\`, Coinbase, Trust, Ledger, etc.), walks browser profile \`Local Extension Settings/\\` LevelDB \`.log\` files matching regex for \`vault\`, \`mnemonic\`, \`seed\`, \`privateKey\`, \`password\`, \`encrypted\`, and recursively scans \`~/Documents\`, \`~/Desktop\`, \`~/Downloads\`, \`~/OneDrive\`, \`~/Dropbox\`, \`~/Google Drive\`, \`~/backup\`, \`~/keys\`, \`~/wallet\`, \`~/crypto\` for seed-phrase and keystore files, exfiltrating hits to the same C2. The package's advertised purpose (\`keywords: \[lodash, utilities\]\`, description "Lodash JavaScript utilities bundle", internal name \`lodash-js\`) does not match the name \`joi-pack\` and does not match the payload — \`index.js\` is an explicit stub ("Just a dummy module. The real payload is in postinstall.js"). Name and keywords are cover-story framing piggybacking on the popular \`joi\` and \`lodash\` packages. ## 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:** joi-pack - **Ecosystem:** npm - **Version:** 1.0.5 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 3 - **Latest version:** 1.0.5 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
