* fix(ci): 移除 PR 对 Project 自动化的触发

* fix: Elasticsearch未授权检测优先于爆破 (#554)

* fix: 修复RDP爆破高误报率问题 (#555)

- 移除 screen.go 中错误的认证结果覆盖逻辑
- 启用 NLA 协议的 ErrorCode 字段检测
- 添加 PubKeyAuth 验证确保认证真正成功
- 修复 io.go 中错误被静默忽略的问题
- 修复 socket.go/io.go 中可能导致 panic 的代码
- 修复 screen.go 中文件句柄泄漏和 log.Panic

* fix: 修复-user/-pwd凭据参数不生效的问题

问题原因：
- Parse()解析凭据后更新globalConfig
- 但BuildConfigFromFlags()创建新Config时使用默认字典
- 导致解析的UserPassPairs等凭据信息被丢弃

修复内容：
1. initialize.go: 将Parse解析的凭据结果应用到新Config
2. credential.go: 单用户密码对时创建UserPassPairs
3. rdp.go: 单凭据测试时跳过指纹识别，减少连接次数

* feat: RDP使用NLA仅验证模式，避免挤掉已登录用户

- 添加ErrNLAAuthSuccess标志用于NLA验证成功信号
- tpkt层支持nlaAuthOnly模式，验证成功后不建立完整会话
- x224层正确传播NLA验证结果
- rdpCrack改用NlaAuth进行凭据验证

* fix: 修复进度条在Windows终端满屏重复输出的问题

- 添加终端宽度检测，动态调整进度条长度
- 使用空格覆盖清除旧内容，避免残留
- 简化进度条格式，确保不超过终端宽度

* feat: 优化日志颜色方案，区分漏洞和普通信息

- 新增 LogVuln 级别（红色），用于漏洞和重要发现
- 密码爆破成功、未授权访问、POC漏洞等改用红色显示
- 普通信息（扫描统计等）改为白色
- Web指纹保持绿色

* refactor: 精简化输出，移除冗余启动信息

- 移除LogPluginInfo/LogPluginInfoWithPort插件信息输出
- 移除alive_scanner冗余统计输出
- 移除port_scan_start扫描开始提示
- 移除handleUDPPorts SNMP死代码

* feat(ldap): 添加NTLM Hash认证支持 (#433)

* chore: 清理无用的 replace 指令

* fix(ping): 修复 TTL expired 导致主机误判为存活的问题

在 ExecCommandPing 中增加错误关键词检测，当 ping 输出包含
TTL expired、Destination unreachable 等错误信息时，不再将
目标主机标记为存活。

Fixes #454

* fix(proxy): 修复透明代理导致输出全端口的问题

在代理初始化时主动探测代理行为，通过连接 RFC 5737 保留的
测试地址来检测是否存在"全回显"问题。如果探测到代理不可靠，
则在端口扫描时跳过所有端口，避免误报。

- 新增 proxyReliable 标志位标记代理可靠性
- 新增 ProbeProxyBehavior 函数探测代理行为
- 端口扫描前检查代理可靠性并输出警告

Fixes #495

* refactor: 移动debug模块到common/debug子包

* fix(web): 修复-u模式下Web插件未执行的问题

* fix: 优化输出格式和颜色显示

- 网段统计格式改为 10.253.0.0/16 网段存活: 26
- WebTitle基础信息改为白色，指纹识别单独绿色输出
- 移除重复的端口数量输出

* fix: URL解析自动补全协议头

-uf 文件中 192.168.1.1:8080 自动转为 http://192.168.1.1:8080

* fix: 修复-u/-uf模式下URLs丢失导致0目标扫描的问题

Parse阶段将URLs设置到全局状态，但Initialize随后创建新状态
并覆盖了全局状态，导致URLs数据丢失。现在在创建新状态前
先保存并迁移Parse阶段设置的URLs和HostPorts数据。

* fix: 智能检测HTTP/HTTPS协议并优化URL显示

- 修复-u/-uf模式URLs丢失导致0目标扫描问题
- detectProtocol改为主动TLS握手检测，不依赖服务名
- WebTitle输出显示完整协议(http/https)
- 隐藏标准端口(80/443)使输出更简洁

* refactor: 精简parsers包，统一配置构建入口

- 删除冗余的中间层（XXXInput、XXXParser类）
- 新增 config_builder.go 统一配置构建
- parsers包从3000+行精简至~540行
- 保留核心函数：ParseIP、ParsePort、文件读取、凭据解析

* test: 扩展parsers单元测试覆盖边缘情况

- 新增内网简写解析测试(192/172/10)
- 新增完整IP范围和无效CIDR测试
- 新增Windows行尾(CRLF)处理测试
- 新增凭据和哈希文件解析测试
- 新增端口解析边缘情况测试
- 测试覆盖率达到94.2%

* refactor: 优化控制台输出格式

- 去掉时间戳，保留[*][+]前缀
- Web输出合并WebTitle和WebFinger为一行
- 有指纹显示绿色[+]，无指纹显示白色[*]
- 格式: code:xxx len:xxx title:xxx server:xxx [指纹]
- 服务探测格式: [Product:xxx ||Version:xxx] Banner:(xxx)
- 字段对齐，输出更清爽

* feat: 添加凭据测试未发现弱密码的提示

- credential_tester.go: 失败时设置 Type=ResultTypeCredential
- scanner.go: 根据结果类型在 error 级别输出'未发现弱密码'提示
- 新增 i18n 翻译 brute_no_weak_pass

使用 -log all 或 -log error 可看到此提示

* refactor(logging): 重构日志级别为层级过滤设计

- LogLevel 从 string 改为 int 类型，支持层级比较
- 层级设计：Debug(0) < Base(1) < Info(2) < Success(3) < Vuln(4) < Error(5)
- 设置一个级别后，显示该级别及以上的日志
- Error 级别始终显示，不会被配置过滤掉
- 保留向后兼容别名（LevelAll, LevelInfoSuccess 等）
- 更新测试以匹配新的层级过滤行为

* style(logging): Error级别日志改为黄色显示

* style(findnet): NetInfo输出改为每行一个IP

* refactor(ms17010): 优化错误提示，明确指出SMBv1不支持等情况

* fix(credential): 修复凭据测试结果不一致的问题

问题原因：
1. 未知错误类型不重试，导致服务端限流时跳过正确密码
2. SSH 错误分类不够准确，某些临时错误未被识别

修复内容：
1. 未知错误改为可重试（可能是临时问题）
2. 增加 SSH 特有的网络错误识别（handshake failed, disconnect 等）

- 新增4阶段深度验证：Banner读取→探测发送→响应等待→最终判定
- 新增SOCKS5错误码和代理错误文本检测
- 优化ProbeProxyBehavior探测逻辑，发送数据验证连接可达性
- 解决透明代理/全回显代理导致的假阳性问题

* fix(proxy): 修复代理深度验证的若干问题

- detector.go: 修复 AutoConfigureProxy 覆盖探测结果的问题
  只有未探测过时才设置默认 proxyReliable 值

- port_scan.go: 改进深度验证机制
  - 使用带 Host header 的 HTTP GET 请求替代 OPTIONS
  - 延长响应等待超时至 2s 以适配慢速服务器
  - 正确重置连接 deadline 避免影响后续操作

* refactor: 统一 common 包文件命名风格

Flag.go -> flag.go

* refactor(proxy): 删除自定义 contains() 函数，改用标准库

- 用 strings.Contains() 替代手写的 contains()
- 删除过时的注释

* fix(parsers): 修复带横杠域名被误识别为IP范围的问题

如 111-555.sss.com 这类域名因包含 - 被错误解析为 IP 范围，
添加 looksLikeIPRange() 检查，只有 - 前是有效 IP 才走范围解析

* fix(proxy): 修复代理模式下服务识别错误和端口漏扫问题

- port_scan.go: 验证通过后重建干净连接，避免HTTP GET探测污染服务识别
- port_scan.go: 优化验证策略，用轻量CRLF探测替代HTTP GET，超时从2.2s降至0.6s
- manager.go: 修正ProbeProxyBehavior判断逻辑，超时应视为代理正常转发

* fix(pool): 移除线程池预分配，优化大规模扫描内存占用

WithPreAlloc(true) 会预先创建所有 worker goroutine，
在大规模扫描(如 25域名×65535端口)时可能导致内存问题

* refactor(logging): 统一日志前缀，删除废弃的 LogBase

- 删除 LogBase 函数，所有调用迁移到 LogInfo/LogError
- 新增 PrefixDebug ([.]) 前缀，所有日志级别现在都有前缀
- 修复日志输出缩进不一致的问题
- 删除未使用的 PrefixDefault 常量

* perf(icmp): 实现自适应等待算法优化存活检测性能

- 新增 waitAdaptive 函数，监控响应增量实现智能提前结束
- 算法保守原则：最小等待1s + 连续500ms无新响应才提前结束
- 添加100ms检查间隔避免CPU空转
- 保留原有最大等待时间(3s/6s)作为兜底
- 添加完整单元测试覆盖各种场景

优化效果：
- 全部响应：~100ms (原3s)
- 无响应：~1s (原3s)
- 部分响应后稳定：~1.5s (原3s)

* perf(scan): 实现启发式优化提升扫描体验

1. 端口优先级排序：高价值端口(80,443,22,3389等)优先扫描
   - 用户能更快看到有意义的结果
   - 不影响端口喷洒策略

2. TCP 补充探测：ICMP 响应率<10%时自动启用
   - 对未响应主机用 TCP 80/443/22/445 补充探测
   - 解决防火墙过滤 ICMP 导致漏检的问题

* refactor(grdp): 精简RDP库，删除认证检测不需要的代码

- 删除 VNC 协议支持 (protocol/rfb, client/rfb.go)
- 删除完整客户端框架 (client/)
- 删除 RemoteApp 等插件 (plugin/)
- 删除 RLE 图形解压 (core/rle.go)
- 删除绘图指令处理 (pdu/orders.go, pdu/gdi.go)
- 精简 screen.go，移除截图和完整会话功能
- 移除未使用的 RGB 转换函数

grdp 代码从 13,044 行精简至 7,581 行，削减 42%

* refactor(common): 删除死代码，优化代码风格

- 删除未使用的 joinStrings/joinInts 函数
- 删除未使用的 memStats 字段和 getMemoryInfo 方法
- 简化 parsePasswords 中的循环为 append(...) 形式

* refactor(services): 统一数据库插件的DBWrapper

4个数据库插件(MySQL、PostgreSQL、MSSQL、Oracle)都有相同的sql.DB包装代码，
合并为通用的SQLDBWrapper，减少重复。

* refactor(core,grdp): 删除未使用的死代码

- 移除 BaseScanStrategy.LogPluginInfoWithPort 方法（无调用者）
- 移除 mcs.go 中被注释的旧 connect 函数实现

* refactor: 删除 deadcode 检测出的未使用函数

- proxy/detector.go: 删除 IsSOCKS5Standard, IsProxyInitialized
- findnet.go: 删除 NetworkInfo.OneLine, TreeFormat 方法
- port_scan.go: 删除 estimateScanTime 函数
- web_scanner.go: 删除 GetFingerprints 函数
- 清理相关测试代码

* refactor: 删除更多未使用的死代码

- parse.go: 删除 RemoveDuplicate 函数及其测试
- parsers.go: 删除 excludeHosts, removeDuplicates 别名函数
- 更新测试使用真正的函数名

* fix(test): 修复 TestParseIP_InvalidIPRange 测试用例

- 删除不合理的测试用例（无效IP被当作普通主机名处理是设计行为）
- 修复测试逻辑，只在真正通过时输出"正确"

* fix(scan): 移除域名预解析，保留原始域名进行扫描

域名预解析会将域名转换为IP，导致虚拟主机场景下HTTP访问失败
（Host头变成IP而非域名，无法正确路由）

* fix(scan): 修复 -hf 参数无法单独使用的问题

* fix(proxy): 修复透明代理环境下 SOCKS5 代理全端口误报问题

问题：在透明代理(TUN模式)环境下使用 SOCKS5 代理扫描时，
会出现全端口开放的误报，因为代理可靠性检测被透明代理污染。

修复方案（参考 fscanx）：
1. 将探针从 CRLF 改为 HTTP GET，更有效检测真实连接状态
2. 删除 "uncertain" 状态，无响应一律判定为端口关闭
3. 调整超时时间以适应代理链路延迟

Fixes #524

* feat(telnet): 新增 telnetd RCE 命令执行验证，修复未授权访问日志级别

* fix: 修复 i18n.Tr vet 报错、Unicode 测试用例，移除过期域名

- 移除 i18n.Tr 中错误的 fmt.Sprintf fallback，消除 go vet 误报
- 修复 match_engine_test Unicode 测试用例与 Latin-1 转换逻辑不匹配
- README 移除过期的 fscan.club 域名
- 添加 .gitattributes 统一换行符为 LF

* refactor: 统一控制台输出风格，使用统一的日志函数

手动合并 PR #558 的改动，适配重构后的代码路径

* fix(ci): 修复版本注入和CI触发配置

- goreleaser ldflags 指向正确的包路径 common.version/commit/date
- version 改为 var 支持 ldflags 注入，banner 显示 commit 和构建日期
- test-build 触发分支增加 dev-* 通配

* fix(ci): 修复 Windows 产物 .exe.exe 双后缀问题

* feat(ci): 扩展构建架构支持 MIPS/ARM/FreeBSD/Solaris
