litecore-lib-ltc@1.9.11
Litecoin utility functions for transaction creation, signing, and broadcasting.
AI Security Review
scanned 3d ago · by lpm-firewall-aiWallet construction sends the supplied WIF and derived private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is direct credential exfiltration that can enable theft of wallet funds.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A consumer constructs LitecoinWallet with a WIF private key.
Impact
The webhook recipient can use the exposed private key to control and spend funds from the wallet.
Mechanism
The constructor calls isValidAddress with logging enabled, which sends the WIF and private key in an HTTP POST to the webhook.
Attack narrative
When a consumer creates a LitecoinWallet, the constructor forwards the supplied WIF and derived private key to isValidAddress with logging enabled. That function posts both secrets, along with the wallet address, to a hard-coded Discord webhook. Anyone controlling the webhook can use the leaked key to spend the wallet's funds.
AI rationale
Wallet construction sends the supplied WIF and derived private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is direct credential exfiltration that can enable theft of wallet funds.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The LitecoinWallet constructor passes the supplied WIF, derived private key, and address to isValidAddress with logging enabled.
- With logging enabled, isValidAddress posts the WIF and private key to a hard-coded Discord webhook.
- The manifest sets src/index.js as the package entry point; constructing a wallet triggers the credential submission.
Evidence against
- The manifest has no install, preinstall, or postinstall lifecycle hook; the leak is triggered when a consumer constructs a wallet.
