我最近收到流量分析器的警告，HTTP 请求的有效负载包含 Windows 可执行文件而不是纯文本。
解释此 HTTP 请求的最佳方法是什么以及如何确定有效负载的实际内容？
谢谢！

答案1
在行 00000110 上，实际的 HTTP 响应负载从该行的第四个字节开始。
有效载荷以字母开头MZ，这是用于 MS-DOS / Windows 可执行文件的标识符。
另外，在第 00000150 行，第四和第五个字母是PE，这表明该文件是 Windows 可移植可执行文件。
有关可移植可执行文件的更多信息可以在维基百科中找到：https://en.wikipedia.org/wiki/Portable_Executable
答案2
读取元数据是有帮助的，尽管它可能是谎言：
ProductVersion 3.6.5
CompanyName SolidStateNetworks
ProductName Direct
因此，下载下载程序. 通过验证签名并通过恶意软件检测（如 VirusTotal）运行来验证其真实性。
无法确定错误的 Content-Type 是否可疑，或者只是 CDN 损坏了标头。我猜这是个人使用，而不是恶意的，但我没有证据证明这一点。
