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:** Wallet private key is exposed in process output when a transaction is sent. - **Trigger:** A caller invokes LitecoinWallet.send() or sendMax(). - **Impact:** Logs or captured stdout may retain a reusable private key, enabling whoever can read them to control the wallet’s funds. - **Evidence paths:** src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:03.991Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** send() calls console.log on the private key’s string representation before proceeding with transaction validation and signing. - **Rationale:** The package’s transaction send method prints the wallet’s private key to stdout, creating an avoidable risk of key exposure in logs. The network activity otherwise matches the wallet’s stated purpose, and no install-time or import-time attack was identified. - **Files touched:** src/index.js - **Network endpoints:** api.blockcypher.com, api.coingecko.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** Calling LitecoinWallet.send() prints the wallet’s private key to stdout before validating the destination or constructing the transaction., The same method uses that private key to sign and broadcast the transaction, so the console output exposes a reusable wallet secret during an ordinary send operation. - **Evidence against:** The package has no install lifecycle hook; its manifest declares only a placeholder test script., Network requests use BlockCypher for Litecoin UTXOs and transaction broadcast, consistent with the package’s stated wallet purpose., The inspected entry point performs network activity through wallet methods rather than at import time. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.4. - Avoid installing litecore-lib-ltc@1.9.4. 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.
