Sinking Yachts 🐟

A C# library for detecting Discord/Steam phishing links using the Sinking Yachts API.

Warning
Sinking Yachts is currently in the process of being discontinued and replaced with the upstream Fish Fish API. Expect this library to eventually become archived and marked as deprecated. Daily statistics have already been shut down.

Usage

Available on NuGet as SinkingYachts, methods are available under the public class YachtsClient.

https://www.nuget.org/packages/SinkingYachts

Features

• Made with .NET 6
• Fully async
• Access to a Discord-related phishing database of over 15 500 confirmed malicious domains
• Regex matching of domains and automatic phishing detection
• Different modes for storing and loading phishing domains
• Instant updates through WebSocket events
• Domain whitelisting to decrease false positives
• Customizable caching to decrease load
