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:** No attack was identified; the network activity is the requested Litecoin UTXO lookup and transaction broadcast. - **Trigger:** A caller explicitly invokes sendLitecoin with a private key, recipient and amount. - **Impact:** Broadcasts the caller-requested Litecoin transaction; the source does not show the WIF being sent to the endpoint. - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:41.547Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function derives the sender address, fetches its UTXOs from api.blockcypher.com, signs a transaction locally and submits the signed transaction to that host. - **Rationale:** The package has no install hook or automatic transfer behavior. Its network calls support its stated purpose: it uses the caller-provided key to sign a requested Litecoin transaction locally and broadcasts the signed transaction through BlockCypher. - **Network endpoints:** api.blockcypher.com ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to src/index.js and declares no install lifecycle hooks; its only script is a placeholder test command., The package exports sendLitecoin(wif, toAddress, amountSatoshis, feeSatoshis), which uses the supplied WIF to build and sign a transaction when called., That function fetches UTXOs for the derived Litecoin address and posts the signed transaction to api.blockcypher.com for broadcast. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.0.0. - Avoid installing litecore-lib-ltc@1.0.0. 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.
