OpenSSF/OSV advisory MAL-2026-6762 confirms this npm version as malicious. node-pino is a one-edit typosquat of the popular \`pino\` logger that ships repackaged \`winston\` plus a malicious \`postinstall\` dropper. On \`npm install\`, the postinstall hook (\`npm run license\` -\> \`node lib/winston/license\`) spawns a DETACHED, unref'd child process that reads an AES-256-CBC-encrypted blob (\`license.list\`, ~211 KB), decrypts it with a hardcoded key/iv, and \`eval()\`s the ~105 KB obfuscated infostealer... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-07-05T22:55:05.668Z - **Finished:** 2026-07-05T22:55:05.668Z - **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 node-pino@2.3.2. - Avoid installing node-pino@2.3.2. 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% node-pino is a one-edit typosquat of the popular \`pino\` logger that ships repackaged \`winston\` plus a malicious \`postinstall\` dropper. On \`npm install\`, the postinstall hook (\`npm run license\` -\> \`node lib/winston/license\`) spawns a DETACHED, unref'd child process that reads an AES-256-CBC-encrypted blob (\`license.list\`, ~211 KB), decrypts it with a hardcoded key/iv, and \`eval()\`s the ~105 KB obfuscated infostealer payload. The stealer targets crypto wallets (exodus.wallet), the macOS Keychain, and Brave/Chrome/Edge user-data, zips the loot to \`p5.zip\`, and exfiltrates via HTTP POST /upload to a hardcoded C2 (port :1224). Structure, the :1224 C2 port, and targeting are CONSISTENT WITH the DPRK 'Contagious Interview' / BeaverTail npm campaign (stated as consistent-with, not a definitive actor attribution). First published 2025-09-16 (single version), it remained live and installable for ~278 days on no advisory list until pkgproof flagged it via semantic name\<-\>content coherence analysis. Indicators of compromise: postinstall -\> \`npm run license\` -\> \`node lib/winston/license\`; detached, unref'd child that outlives \`npm install\`; AES-256-CBC-encrypted \`license.list\` (~211 KB) with a hardcoded key/iv in \`parse.js\`; \`eval()\` of the ~105 KB decrypted obfuscated payload; C2 on port :1224; exfiltration via zip to \`p5.zip\` and HTTP POST /upload; targets exodus.wallet, the macOS Keychain, and Brave/Chrome/Edge user-data. All IOCs were extracted by STATIC/OFFLINE analysis (offline decryption of the bundled blob); the attacker payload was never executed, so no live C2 callback or runtime artifact was generated by this analysis. The decryption key, the deobfuscated payload, and the exact C2 host are deliberately omitted; no specific IP is asserted. ## 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:** node-pino - **Ecosystem:** npm - **Version:** 2.3.2 - **Version published:** 2025-09-16T02:36:30.513Z - **Package first seen:** 2026-07-05T22:55:05.668Z - **Package last seen:** 2026-08-27T05:27:48.464Z - **Known versions:** 2 - **Latest version:** 0.0.1-security - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [WEB]()
