AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Wallet construction sends the supplied WIF and derived private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is direct credential exfiltration that can enable theft of wallet funds. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-02T06:37:19.439Z - **Finished:** 2026-11-02T06:37:44.709Z - **Download time:** 260 ms - **Static scan time:** 17 ms - **AI review time:** 24993 ms - **Total time:** 25270 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 Litecoin wallet credentials to a hard-coded Discord webhook. - **Trigger:** A consumer constructs LitecoinWallet with a WIF private key. - **Impact:** The webhook recipient can use the exposed private key to control and spend funds from the wallet. - **Evidence paths:** src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:44.709Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The constructor calls isValidAddress with logging enabled, which sends the WIF and private key in an HTTP POST to the webhook. - **Attack narrative:** When a consumer creates a LitecoinWallet, the constructor forwards the supplied WIF and derived private key to isValidAddress with logging enabled. That function posts both secrets, along with the wallet address, to a hard-coded Discord webhook. Anyone controlling the webhook can use the leaked key to spend the wallet's funds. - **Rationale:** Wallet construction sends the supplied WIF and derived private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is direct credential exfiltration that can enable theft of wallet funds. - **Files touched:** src/index.js, src/wallet.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:** The LitecoinWallet constructor passes the supplied WIF, derived private key, and address to isValidAddress with logging enabled., With logging enabled, isValidAddress posts the WIF and private key to a hard-coded Discord webhook., The manifest sets src/index.js as the package entry point; constructing a wallet triggers the credential submission. - **Evidence against:** The manifest has no install, preinstall, or postinstall lifecycle hook; the leak is triggered when a consumer constructs a wallet. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.11. - Avoid installing litecore-lib-ltc@1.9.11. 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.
