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:** Calling send() exposes the wallet’s private key in stdout, where terminal capture or application logs may retain it. - **Trigger:** A caller invokes LitecoinWallet.send() or sendMax(). - **Impact:** Anyone with access to captured stdout or logs may obtain the private key and spend the wallet’s funds. - **Evidence paths:** src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:48.162Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** send() converts the stored private key to a string and logs it before validating the destination or signing and broadcasting the transaction. - **Rationale:** The package does not show malicious install-time or import-time behavior, but its send method prints the wallet’s private key during an ordinary transaction operation. This creates a serious local exposure risk, so the release should be warned on pending review or correction. - **Files touched:** src/index.js, src/wallet.js, src/api,js - **Network endpoints:** https://api.blockcypher.com/v1/ltc/main ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** Calling LitecoinWallet.send() writes this.privateKey.toString() to stdout before address validation., The class stores a private key created from the caller-supplied WIF, and send() later uses that key to sign a transaction., The manifest has no install lifecycle hook; network calls are part of explicit wallet operations. - **Evidence against:** The key is not sent to a remote host in the inspected source., The package’s network requests use BlockCypher for Litecoin balance, UTXO, fee and transaction broadcast operations. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.3. - Avoid installing litecore-lib-ltc@1.9.3. 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.
