AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Direct source inspection confirms an automatic install-time secret-harvesting and exfiltration chain. This is concrete malicious behavior, not a package-aligned network use. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-05T11:09:11.403Z - **Finished:** 2026-08-05T11:09:37.562Z - **Download time:** 505 ms - **Static scan time:** 14 ms - **AI review time:** 25639 ms - **Total time:** 26159 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation executes credential and wallet harvesting from the installing user's home directory, then exfiltrates the collected contents. The runtime entrypoint is otherwise a simple ethers re-export. - **Trigger:** npm installation invokes the postinstall lifecycle hook. - **Impact:** Exposure of cloud credentials, SSH keys, npm tokens, Git configuration, environment secrets, and cryptocurrency wallet material. - **Evidence paths:** package.json, postinstall.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T11:09:37.562Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time credential harvesting and HTTPS exfiltration - **Attack narrative:** Installing the package runs postinstall.js automatically. It reads targeted secret files and scans hidden home-directory folders for key, wallet, seed, JSON, PEM, and key files, serializes their contents with host and username metadata, and sends the result in an HTTPS POST to a fixed Pipedream endpoint. - **Rationale:** Direct source inspection confirms an automatic install-time secret-harvesting and exfiltration chain. This is concrete malicious behavior, not a package-aligned network use. - **Files touched:** package.json, postinstall.js, .env, .env.local, .env.production, .env.development, .npmrc, .aws/credentials, .aws/config, .ssh/id\_rsa, .ssh/id\_ed25519, .ssh/id\_ecdsa, .config/solana/id.json, .ethereum/keystore, .gitconfig - **Network endpoints:** enxhcjpo5ev.x.pipedream.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs \`node postinstall.js\` during installation., postinstall.js collects .env, AWS, SSH, Solana, Ethereum, npm, and Git files from the home directory., postinstall.js scans hidden home subdirectories for wallet/key/seed-like files., Collected contents are POSTed to enxhcjpo5ev.x.pipedream.net. - **Evidence against:** index.js only re-exports the ethers dependency., No legitimate install-time setup behavior is present. ## Affected versions and remediation This report applies to ethers-lib@1.0.1. - Avoid installing ethers-lib@1.0.1. 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.
