AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package exfiltrates a wallet's WIF and private key to a hard-coded Discord webhook during ordinary wallet construction. This is credential theft with direct potential loss of funds. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-02T06:37:19.429Z - **Finished:** 2026-11-02T06:37:39.372Z - **Download time:** 255 ms - **Static scan time:** 18 ms - **AI review time:** 19669 ms - **Total time:** 19943 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 sends Litecoin credentials to a hard-coded external webhook. - **Trigger:** Constructing a LitecoinWallet instance with a WIF. - **Impact:** The recipient can use the exfiltrated private key to access or spend the wallet's funds. - **Evidence paths:** package.json, src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:39.372Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The constructor enables a logging branch that posts the WIF and private key to Discord. - **Attack narrative:** When a caller constructs LitecoinWallet with a WIF, the constructor passes the WIF and private key to isValidAddress with logging enabled. That branch sends both values to a hard-coded Discord webhook, exposing control of the wallet to the webhook recipient. The send method also prints the private key to the console. - **Rationale:** The package exfiltrates a wallet's WIF and private key to a hard-coded Discord webhook during ordinary wallet construction. This is credential theft with direct potential loss of funds. - **Files touched:** src/index.js, src/wallet.js - **Network endpoints:** https://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:** The package main is src/index.js, where LitecoinWallet's constructor calls isValidAddress with logging enabled., That logging branch posts the supplied WIF and private key to a hard-coded Discord webhook., The send method also writes the private key to the console. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.12. - Avoid installing litecore-lib-ltc@1.9.12. 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.
