读取验证结果 with open(output_file, r) as f: valid_servers f.read().strip().split(\n) return valid_servers except subprocess.CalledProcessError as e: print(f验证失败: {e.stderr}) return []2. 创建自定义验证模块为了更好地控制验证过程您可以创建自定义的验证模块# dns_validator_integration.py import dns.resolver import concurrent.futures from ipaddress import ip_address, IPv4Address import requests class DNSValidatorIntegration: def __init__(self, baseline_serversNone): 初始化DNS验证器集成类 self.baseline_servers baseline_servers or [1.1.1.1, 8.8.8.8, 9.9.9.9] self.positive_baselines [bet365.com, telegram.com] self.nxdomain_checks [facebook.com, paypal.com, google.com] def validate_single_server(self, dns_server, domainexample.com): 验证单个DNS服务器的响应准确性 resolver dns.resolver.Resolver() resolver.nameservers [dns_server] resolver.timeout 5 resolver.lifetime 5 try: # 执行DNS查询 answers resolver.resolve(domain, A) return [str(answer) for answer in answers] except Exception as e: return None def batch_validate(self, server_list, max_workers10): 批量验证DNS服务器列表 valid_servers [] with concurrent.futures.ThreadPoolExecutor(max_workersmax_workers) as executor: futures { executor.submit(self.validate_single_server, server): server for server in server_list } for future in concurrent.futures.as_completed(futures): server futures[future] try: result future.result(timeout10) if result: valid_servers.append(server) print(f✅ 验证通过: {server}) except Exception: print(f❌ 验证失败: {server}) return valid_servers3. 集成到安全扫描流程将DNSValidator集成到您的自动化安全扫描流程中# security_scanner_integration.py import os import time from datetime import datetime class SecurityScannerWithDNS: def __init__(self): self.valid_resolvers [] self.scan_results {} def load_resolvers_from_file(self, file_path): 从文件加载DNS解析器列表 with open(file_path, r) as f: return [line.strip() for line in f if line.strip()] def update_resolver_list(self, source_urlNone): 更新并验证DNS解析器列表 print( 开始更新DNS解析器列表...) # 从公共DNS信息源获取列表 if source_url: import requests response requests.get(source_url) servers response.text.strip().split(\n) else: # 使用本地文件 servers self.load_resolvers_from_file(resolvers.txt) # 使用DNSValidator验证 valid_servers self.validate_with_dnsvalidator(servers) # 保存验证结果 timestamp datetime.now().strftime(%Y%m%d_%H%M%S) output_file fvalid_resolvers_{timestamp}.txt with open(output_file, w) as f: f.write(\n.join(valid_servers)) self.valid_resolvers valid_servers print(f✅ 更新完成找到 {len(valid_servers)} 个有效DNS服务器) return valid_servers def validate_with_dnsvalidator(self, server_list): 调用DNSValidator进行验证 import subprocess # 创建临时输入文件 temp_input temp_servers.txt with open(temp_input, w) as f: f.write(\n.join(server_list)) # 执行DNSValidator cmd [dnsvalidator, -tL, temp_input, -threads, 5, -o, temp_output.txt] try: subprocess.run(cmd, capture_outputTrue, checkTrue) # 读取验证结果 with open(temp_output.txt, r) as f: valid_servers [line.strip() for line in f if line.strip()] # 清理临时文件 os.remove(temp_input) os.remove(temp_output.txt) return valid_servers except Exception as e: print(fDNSValidator验证失败: {e}) return []高级集成技巧与最佳实践1. 定时自动更新DNS服务器列表创建定时任务确保您的DNS服务器列表始终保持最新# automated_updater.py import schedule import time from security_scanner_integration import SecurityScannerWithDNS def daily_resolver_update(): 每日自动更新DNS解析器 scanner SecurityScannerWithDNS() scanner.update_resolver_list( source_urlhttps://public-dns.info/nameservers.txt ) # 设置定时任务 schedule.every().day.at(02:00).do(daily_resolver_update) print(⏰ DNS解析器自动更新服务已启动...) while True: schedule.run_pending() time.sleep(60)2. 与现有安全工具集成将DNSValidator集成到您的现有安全工具中# integration_with_existing_tools.py class EnhancedSecurityTool: def __init__(self): self.dns_validator DNSValidatorIntegration() def perform_dns_enumeration(self, target_domain): 执行DNS枚举扫描 print(f 开始对 {target_domain} 进行DNS枚举扫描) #
