LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. 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:** Explicit wallet transfers disclose the wallet’s private key in process output, creating a risk that logs expose it. - **Trigger:** Calling LitecoinWallet.send() or sendMax(). - **Impact:** Anyone with access to captured process output or logs may obtain the private key and control the wallet. - **Evidence paths:** src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:36:53.148Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The transfer method writes the private key string to stdout before it validates the destination, signs the transaction, and broadcasts it. - **Rationale:** This is a serious private-key disclosure in the explicit transfer path, but the source does not show the key being sent to a remote host or exposed automatically at install or import. Treat it as a security risk warranting a warning rather than a confirmed malicious attack. - **Files touched:** src/index.js, src/wallet.js, src/api.js - **Network endpoints:** api.blockcypher.com, api.coingecko.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The package loads src/index.js as its main entry and declares no install lifecycle hook., LitecoinWallet.send prints this.privateKey.toString() to stdout before validating and processing a transfer., The wallet constructor obtains and retains a private key from the supplied WIF., The send method signs the transaction and then broadcasts it through the BlockCypher API., Balance lookup contacts BlockCypher and CoinGecko for the requested address balance and Litecoin price. - **Evidence against:** The private-key disclosure occurs when send or sendMax is called, rather than during installation or module import., The API requests use public blockchain and market-price endpoints for the package’s stated wallet functions. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.7. - Avoid installing litecore-lib-ltc@1.9.7. 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.
