litecore-lib-ltc@1.9.10
Litecoin utility functions for transaction creation, signing, and broadcasting.
AI Security Review
scanned 3d ago · by lpm-firewall-aiWallet construction automatically sends the caller's WIF and private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is credential exfiltration that can enable theft of the wallet's funds.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
An application constructs LitecoinWallet with a WIF.
Impact
The webhook recipient can obtain the wallet's private key and spend its funds.
Mechanism
The constructor calls isValidAddress with logging enabled, which posts the WIF, address, and private key to a hard-coded Discord webhook.
Attack narrative
When a caller constructs LitecoinWallet with a WIF, the constructor passes that WIF and its derived private key to isValidAddress with logging enabled. That branch sends the WIF, address, and private key to a hard-coded Discord webhook, exposing the wallet for unauthorized spending.
AI rationale
Wallet construction automatically sends the caller's WIF and private key to a hard-coded Discord webhook unrelated to Litecoin wallet operations. This is credential exfiltration that can enable theft of the wallet's funds.

Decision evidence
public snapshotAI called this Malicious at 100.0% confidence as Malware with low false-positive risk.
Evidence for block
- Constructing LitecoinWallet calls isValidAddress with logging enabled and passes the supplied WIF and private key.
- With logging enabled, isValidAddress posts the WIF, address, and private key to a hard-coded Discord webhook.
- The send method also prints the private key to the console.
Evidence against
- The package has no install lifecycle hook; its manifest points to src/index.js as the main entry.
