QQNT Windows 客户端 10 | 11 | 请在官方网站下载 QQNT Windows 客户端。 12 | 13 | 本文所述的方法在 9.9.6.20201, 9.9.6-19689, 9.9.6-19189 版本中测试通过。根据参考资料的描述，在 9.9.3-17749, 9.9.3-17412 版本也测试通过。 14 | 15 | 2. IDA Pro 16 | 17 | 下载地址：，解压后根目录的 `ida64.exe` 为本文需要使用的可执行文件。 18 | 19 | 3. DB Browser for SQLite 20 | 21 | 下载地址：，解压后根目录的 `DB Browser for SQLCipher.exe` 为本文需要使用的可执行文件。 22 | 23 | 4. Python 3 24 | 25 | 推荐使用 >=3.8 的版本，并添加到 PATH 环境变量中。 26 | 27 | ## 聊天记录导出 28 | 29 | 由于聊天记录数据库文件是加密的，需要先获取数据库密码。 30 | 31 | ### 获取数据库密码 32 | 33 | 方法来源： 34 | 35 | 1. 打开 `ida64.exe`，选择新建项目。 36 | 37 | 2. 在弹出的资源管理器界面中定位到 QQNT 安装目录下的 `./resources/app/versions/{version}` 文件夹，其中 `{version}` 为 QQNT 的版本号。在右下角过滤器中选择全部文件，单击 `wrapper.node` 文件，并点击右下角的 "Open" 按钮。 38 | 39 | ![](./images/ida_0.png) 40 | 41 | 3. 保持默认导入选项，点击 "OK" 按钮。如果有弹出 symbol 文件相关提示框点击 "No"。等待文件加载完成。 42 | 43 | 4. 按快捷键 Shift + F12 打开 Strings 标签，等待页面加载完成。切换到 Strings 标签使用鼠标单击内部区域，按快捷键 Ctrl + F 打开搜索框，输入 `nt_sqlite3_key_v2`。 44 | 45 | ![](./images/ida_1.png) 46 | 47 | 5. 双击 `nt_sqlite3_key_v2: db=%p zDb=%s` 一行，跳转到 IDA View-A 标签的对应行。 48 | 49 | 6. 点击顶部导航栏 "Options" 中的 "General..." 菜单项，打开 IDA Options 窗口。在 Disassembly 标签页中，将 Display assembly lines 中的 Source line numbers 勾选上，点击 "OK" 按钮。 50 | 51 | ![](./images/ida_2.png) 52 | 53 | ![](./images/ida_3.png) 54 | 55 | 7. 在 IDA View-A 标签中，单击 `nt_sqlite3_key_v2` 的名称 `aNtSqlite3KeyV2`，按快捷键 X 打开交叉引用窗口。 56 | 57 | ![](./images/ida_4.png) 58 | 59 | 8. 双击第一条结果，转到引用位置。 60 | 61 | ![](./images/ida_5.png) 62 | 63 | 9. 按快捷键 F5 进行反编译，如果有弹出窗口点击 "Yes"。等待反编译完成。 64 | 65 | ![](./images/ida_6.png) 66 | 67 | 10. 单击引用语句的左侧蓝色圆点添加断点。 68 | 69 | ![](./images/ida_7.png) 70 | 71 | 11. 修改 Debugger 下拉框的值为 "Local Windows Debugger"。 72 | 73 | ![](./images/ida_8.png) 74 | 75 | 12. 如果有正在运行的 QQNT 客户端，先全部退出。打开一个新的 QQNT 客户端，进入登录界面并暂停操作。 76 | 77 | 13. 在 IDA 中点击顶部导航栏 "Debugger" 中的 "Attach to process..." 菜单项，打开 "Attach to process" 窗口。从最后开始找到第一个 `QQ.exe` 进程，双击打开。 78 | 79 | ![](./images/ida_9.png) 80 | 81 | 14. 等待加载完成后按快捷键 F9 继续运行。 82 | 83 | 15. 进行登录操作，触发断点。 84 | 85 | 16. 在 IDA 中点击顶部导航栏 "Debugger" 中的 "Debugger windows" 菜单项，打开 Locals 选项卡。 86 | 87 | ![](./images/ida_a.png) 88 | 89 | 17. 右击 Locals 选项卡的 `a3`，点击 "Jump to..." 菜单项。 90 | 91 | ![](./images/ida_b.png) 92 | 93 | 18. 记录对应地址从 `0` 到 `F` 的 16 个字节对应的字符串，即为数据库密码。 94 | 95 | ![](./images/ida_c.png) 96 | 97 | ### 数据导出 98 | 99 | 消息数据库默认位于 `%USERPROFILE%/Documents/Tencent Files/{qq}/nt_qq/nt_db/` 目录下，其中 `{qq}` 为 QQ 号。复制该目录下的 `nt_msg.db` 文件到本项目的 `./data/` 目录下。 100 | 101 | 1. 在复制过来的 `nt_msg.db` 所在文件夹运行以下命令，分离数据库头部与数据库本体。如果数据库文件较大，可能会花费较长时间。 102 | 103 | 使用 PowerShell 7： 104 | 105 | ```powershell 106 | $content = Get-Content -Path nt_msg.db -AsByteStream -Raw 107 | $content_header = $content[0..1024] 108 | $content_body = $content[1024..($content.length-1)] 109 | Set-Content -Path nt_msg.header.txt -Value $content_header -AsByteStream 110 | Set-Content -Path nt_msg.body.db -Value $content_body -AsByteStream 111 | ``` 112 | 113 | 如果安装有 WSL，可以在 WSL 中转到对应文件夹运行以下命令： 114 | 115 | ```bash 116 | cat nt_msg.db | head -c 1024 > nt_msg.header.txt 117 | cat nt_msg.db | tail -c +1025 > nt_msg.body.db 118 | ``` 119 | 120 | 2. 使用文本编辑器打开文件 `nt_msg.header.txt`，如果存在文本 `HMAC_` 则记录对应的 HMAC 算法。例如 `HMAC_SHA1` 对应的 HMAC 算法为 `SHA1`，如果没有对应文本则为 `SHA512`。 121 | 122 | 3. 打开 `DB Browser for SQLCipher.exe`，点击 "File" 菜单中的 "Open Database..." 菜单项，打开 `nt_msg.body.db` 文件。 123 | 124 | 4. 在弹出的 "SQLCipher encryption" 窗口中的 Password 输入框中输入数据库密码，Encryption settings 选择 "Custom"，修改 KDF iterations 为 `4000`，修改 HMAC algorithm 为第 2 步所获取的 HMAC 算法，点击 "OK" 按钮。 125 | 126 | ![](./images/sql_0.png) 127 | 128 | 5. 在 Database Structure 标签页中，可以查看数据库中的表。其中 `c2c_msg_table` 表为私聊消息表；`group_msg_table` 表为群聊消息表。 129 | 130 | ![](./images/sql_1.png) 131 | 132 | 6. 在 Browse Data 标签页中，可以查看表中的数据；在 Execute SQL 标签页中，可以执行 SQL 语句。如果数据量不大，可以直接使用 SQL 语句进行数据分析。数据量较大或需要进行消息内容分析时，需要先进行数据过滤，然后导出。需要过滤单个群聊的 2024 年数据时，在 Execute SQL 标签页中执行（快捷键 F5）以下 SQL 语句，其中 `{group_id}` 为群号。 133 | 134 | ```sql 135 | SELECT * 136 | FROM group_msg_table 137 | WHERE "40027" = {group_id} 138 | AND "40058" >= 1704038400 139 | AND "40058" < 1735574400 140 | ``` 141 | 142 | 7. 待执行生成后，将结果保存为 view 并命名，如 `group_export`。 143 | 144 | ![](./images/sql_2.png) 145 | 146 | 8. 在 "File" 菜单中选择 "Export" 菜单项，点击 "Table(s) to JSON..."。 147 | 148 | ![](./images/sql_3.png) 149 | 150 | 9. 选择刚刚保存的 view，点击 "Save" 按钮，选择路径为本项目的 `./data/` 目录，等待导出完成。 151 | 152 | ![](./images/sql_4.png) 153 | 154 | ## 数据分析 155 | 156 | TODO 157 | 158 | ## 数据库字段含义 159 |
