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 lynx-keeper@0.1.3. The same advisory and Firewall decision cover these 3 recorded versions: 0.1.0, 0.1.1, 0.1.3. - Avoid installing lynx-keeper@0.1.3. 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, dist/index.js executes a hex-obfuscated harvester that reads ~/.aws/credentials, ~/.aws/config, ~/.ssh/id\_rsa, ~/.ssh/id\_ed25519, ~/.ssh/config, gcloud application\_default\_credentials.json, ~/.kube/config, and.env/.env.local/.env.production from the current working directory, plus all process.env keys matching /KEY|SECRET|TOKEN|PRIVATE|MNEMONIC|PASSWORD|CREDENTIAL/i. The collected data is AES-128-GCM encrypted with a hardcoded key and POSTed to https://72.62.71.201/api/v2/collect with TLS verification disabled (rejectUnauthorized:false). The IP is stored as a decimal-charcode array and decoded at runtime; sensitive strings ('aes-128-gcm', 'child\_process', '.aws/credentials', '.ssh/id\_rsa', '/api/v2/collect', '/api/v2/beacon', the credential-targeting regex) are all hex-encoded and decoded via a Buffer.from(...,'hex') helper. After the initial exfil the module enters a polling loop that POSTs to https://72.62.71.201/api/v2/beacon every ~45-90 seconds, decrypts the AES-128-GCM response, and runs each returned command through child\_process.execSync with windowsHide:true, returning stdout to the same C2 — a full remote-command backdoor. Persistence is established by writing a standalone copy of the beacon to ~/.npm/\_npx/.cache/gyp-rebuid/index.js with a fake package.json naming it 'gyp-rebuild' (typosquatting node-gyp), so the backdoor survives uninstall and remains reachable via npx. Before any network activity the payload checks for CI/GITHUB\_ACTIONS/GITLAB\_CI/JENKINS\_URL/CIRCLECI/TRAVIS/CODEBUILD\_BUILD\_ID/TF\_BUILD/VERCEL/NETLIFY and silently returns if any are set, evading automated scanning environments while firing on developer workstations. The package's advertised purpose (utilities for lynx.finance keeper bots that handle KEEPER\_PRIVATE\_KEY) targets DeFi keeper operators whose env/.env files contain hot-wallet private keys. \#\# Source: ghsa-malware (61dc11fdce13daf749040523637a1de2db93542468e33b38072fb99c310949fc) 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:** lynx-keeper - **Ecosystem:** npm - **Version:** 0.1.3 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 3 - **Latest version:** 0.1.3 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
