OpenSSF/OSV advisory MAL-2026-18442 confirms this npm version as malicious. Malicious package. \`litecore-lib-ltc\` is a typosquat of the legitimate \`litecore-lib\` Litecoin library. It harvests Litecoin wallet keys and addresses, uses the public BlockCypher API (api.blockcypher.com) to identify which harvested addresses are funded, and exfiltrates the stolen wallet material to an attacker-controlled Discord webhook.

Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The send method exposes the wallet’s private key in process output. - **Trigger:** A caller invokes LitecoinWallet.send(), including through sendMax(). - **Impact:** Logs or captured stdout may expose a key that controls the wallet’s funds. - **Evidence paths:** src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:36:40.697Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The method writes this.privateKey.toString() to console before transaction construction and broadcast. - **Rationale:** The package does not appear to steal keys over the network or act automatically, but its transaction method prints the private key to stdout. This creates a material key exposure risk, so the release should be downgraded to a warning. - **Files touched:** src/index.js - **Network endpoints:** api.blockcypher.com, api.coingecko.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** Calling LitecoinWallet.send() logs the wallet’s private key to stdout before validating the destination or sending a transaction., The package has no install lifecycle hook; its entry point is src/index.js. - **Evidence against:** The network requests support the wallet’s stated Litecoin balance, fee, and transaction broadcasting functions., The key logging occurs when send() is called, not automatically on import. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.6. - Avoid installing litecore-lib-ltc@1.9.6. 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.
