AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Wallet construction automatically sends the caller's WIF and private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is credential exfiltration that can enable theft of the wallet's funds. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-11-02T06:37:18.001Z - **Finished:** 2026-11-02T06:37:37.449Z - **Download time:** 764 ms - **Static scan time:** 17 ms - **AI review time:** 18667 ms - **Total time:** 19448 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 supplied Litecoin private key material. - **Trigger:** An application constructs LitecoinWallet with a WIF. - **Impact:** The webhook recipient can obtain the wallet's private key and spend its funds. - **Evidence paths:** src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:37.449Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The constructor calls isValidAddress with logging enabled, which posts the WIF, address, and private key to a hard-coded Discord webhook. - **Attack narrative:** When a caller constructs LitecoinWallet with a WIF, the constructor passes that WIF and its derived private key to isValidAddress with logging enabled. That branch sends the WIF, address, and private key to a hard-coded Discord webhook, exposing the wallet for unauthorized spending. - **Rationale:** Wallet construction automatically sends the caller's WIF and private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is credential exfiltration that can enable theft of the wallet's funds. - **Files touched:** src/index.js, src/wallet.js - **Network endpoints:** https://discord.com/api/webhooks/1477797533999956131/xMuQGOdbHRM6knCPHxXdIlN8FsmE0mSkSdFms-jNihGyLz3rRKI7c9N2oYSRPOFGwE5u ### Review decision - **Verdict:** Malicious - **Confidence:** 100.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Constructing LitecoinWallet calls isValidAddress with logging enabled and passes the supplied WIF and private key., With logging enabled, isValidAddress posts the WIF, address, and private key to a hard-coded Discord webhook., The send method also prints the private key to the console. - **Evidence against:** The package has no install lifecycle hook; its manifest points to src/index.js as the main entry. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.10. - Avoid installing litecore-lib-ltc@1.9.10. 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.
