在Java中检查IP地址是否存在已知威胁或是Tor出口节点服务器可以通过查询一些公共的IP地址黑名单服务或使用Tor的IP地址列表来实现。以下是一些步骤和代码示例:
可以使用一些公共的IP地址黑名单服务来检查IP地址是否被标记为威胁。一个常用的服务是Spamhaus,它提供了公共的DNSBL(DNS黑名单)服务。
import java.net.InetAddress; import java.net.UnknownHostException; import java.util.Arrays; import java.util.List; public class ThreatIntelChecker { private static final List<String> BLACKLIST_DNS_SERVERS = Arrays.asList( "zen.spamhaus.org" // Add more DNSBL servers as needed ); public static boolean isThreatIP(String ipAddress) { for (String dnsServer : BLACKLIST_DNS_SERVERS) { if (isListedInDNSBL(ipAddress, dnsServer)) { return true; } } return false; } private static boolean isListedInDNSBL(String ipAddress, String dnsServer) { try { InetAddress address = InetAddress.getByName(ipAddress + "." + dnsServer); return address.isReachable(5000); // Timeout of 5 seconds } catch (UnknownHostException e) { // Handle UnknownHostException return false; } catch (Exception e) { // Handle other exceptions return false; } } public static void main(String[] args) { String testIP = "192.168.1.1"; // Replace with the IP you want to check boolean isThreat = isThreatIP(testIP); System.out.println("Is Threat IP? " + isThreat); } }
Tor维护了一个公共的IP地址列表,您可以使用它来检查IP地址是否是Tor出口节点。
import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; public class TorChecker { private static final String TOR_EXIT_NODE_LIST_URL = "https://check.torproject.org/exit-addresses"; public static boolean isTorExitNode(String ipAddress) { try { String torExitNodes = fetchTorExitNodes(); return torExitNodes.contains(ipAddress); } catch (IOException e) { // Handle IOException return false; } } private static String fetchTorExitNodes() throws IOException { URL url = new URL(TOR_EXIT_NODE_LIST_URL); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); try (BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()))) { StringBuilder response = new StringBuilder(); String line; while ((line = reader.readLine()) != null) { response.append(line).append("\n"); } return response.toString(); } finally { connection.disconnect(); } } public static void main(String[] args) { String testIP = "185.220.100.253"; // Replace with the IP you want to check boolean isTor = isTorExitNode(testIP); System.out.println("Is Tor Exit Node? " + isTor); } }
请注意,这些示例代码仅作为起点,实际上要在生产环境中使用时需要更多的错误处理和优化。此外,黑名单服务和Tor节点列表可能会发生变化,因此您可能需要定期更新您的应用程序以确保准确性。
