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:** The send operation exposes a wallet's private key in stdout, creating a risk that callers or log collectors will retain or disclose it. - **Trigger:** A caller invokes LitecoinWallet.send() or sendMax(). - **Impact:** Private key material may be captured by terminal logs, process supervisors, or application logging systems and used to spend the wallet's funds. - **Evidence paths:** src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:36:41.065Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** send() calls console.log(this.privateKey.toString()) before validating the recipient or constructing the transaction. - **Rationale:** The package has no install-time behavior or evident unrelated network collection, but its wallet send path unnecessarily prints the private key. That creates a serious credential exposure risk, though the reviewed source does not establish remote exfiltration. - **Files touched:** src/index.js, src/wallet.js, src/api,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:** The package entry point is src/index.js, and its send method prints the wallet private key to stdout before validating the destination or building a transaction., Wallet construction stores the private key returned from WIF parsing, so the value printed by send is secret key material. - **Evidence against:** The manifest has no install lifecycle scripts; its only script is a placeholder test command., Network calls use public BlockCypher and CoinGecko APIs for Litecoin balances, fees, UTXOs, and transaction broadcasting. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.5. - Avoid installing litecore-lib-ltc@1.9.5. 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.
