我们点开发行说明,发现了一些蛛丝马迹:The firmware v3.15 must be upgraded from the transitional version of firmware v303WWb04_middle. 🚀🚀也就是固件 v3.15 必须从固件v303WWb04_middle的过渡版本升级。所以我们可以从固件v303WWb04_middle入手。 固件解密 🚀🚀我们执行binwalk -Me DIR822C1_FW303WWb...
结合之前固件的三种加密更新方式,这个 firmware v303WWb04_middle 很可能就含有解密程序的中间过渡用未加密固件。所以我们就可以想办法下载这个固件并找到解密方案,从而解密 DIR822C1_FW315WWb02 固件。 这个固件我们可以去D-Link搭建的FTP服务器里下载(嫌麻烦可以在附件下载) 该中间过渡用的版本的固件没有加密,可以 ...
该文件包含字符串值_wrgac43s_dlink.2015dir822c1,我认为它是解密密钥。另一个参数-i是输入文件,它将是新接收到的加密固件文件。现在,让我们尝试使用qemu仿真器解密此固件。qemu-mips -L . ./usr/sbin/encimg -d -i <path to encrypted firmware> -s wrgac43s_dlink.2015_dir822c1 Qemu用户空间仿真...
以D-Link DIR-822-US 3.15B02固件为例，下载并用binwalk分析。显示熵值几乎为1，表明固件各部分加密。查找发布说明，推测中间过渡版本含解密程序。下载中间未加密版本，提取文件系统。在固件目录搜索关键字符串，找到StartFirmwareDownload.php文件线索，包含加密解密相关代码。解析代码，了解加密解密流程，确定...
