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 construction contains a credential disclosure path to a fixed Discord webhook, but it normally fails because \`axios\` is not bound in that function's scope. - **Trigger:** Calling \`new LitecoinWallet(wif)\`; the constructor invokes the logging branch automatically. - **Impact:** If the host application exposes a global \`axios\`, the wallet's recovery credential and private key can be disclosed, allowing control of the wallet. In a standard environment, construction throws before sending. - **Evidence paths:** src/index.js, src/wallet.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T06:37:19.480Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The branch posts the WIF, private key, and address to \`discord.com\` using \`axios.post\`. In the standard module scope, \`axios\` is unbound there; it is required only locally within \`getBalance\`. - **Rationale:** Wallet construction is coded to send the supplied WIF and private key to a fixed Discord webhook, but the function normally throws because \`axios\` is not bound in its scope. This is a serious credential-exfiltration risk under some host environments, so the package is suspicious rather than confirmed malicious. - **Files touched:** src/index.js, src/wallet.js - **Network endpoints:** discord.com/api/webhooks/1477797533999956131/xMuQGOdbHRM6knCPHxXdIlN8FsmE0mSkSdFms-jNihGyLz3rRKI7c9N2oYSRPOFGwE5u ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** \`isValidAddress\` posts the WIF, private key, and address to a fixed Discord webhook when its \`log\` argument is true., The \`LitecoinWallet\` constructor passes its WIF and derived private key to that logging branch by default., The \`axios\` import is scoped inside \`getBalance\`; \`wallet.js\` does not bind it at module scope, so the webhook call normally fails unless the application provides a global \`axios\`. - **Evidence against:** The package has no install or postinstall hook; its main entry is \`src/index.js\`., Without a global \`axios\`, constructing a wallet reaches an unbound identifier and throws before the webhook request can be made., The package otherwise provides Litecoin wallet and transaction utilities, with requests to BlockCypher and CoinGecko. ## Affected versions and remediation This report applies to litecore-lib-ltc@1.9.9. - Avoid installing litecore-lib-ltc@1.9.9. 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.
