meg是一款功能强大的URL信息收集工具,在该工具的帮助下,广大研究人员能够在不影响目标主机和服务器的情况下,尽可能多地收集与目标主机相关的大量URL地址。
该工具能够同时从多台主机中获取多条URL路径,而且在转移到下一个路径并重复之前,该工具还能够在所有主机中寻找同一条路径。
该工具的运行速度非常快,并且不会导致目标主机被恶意流量所淹没,也就是不会影响目标主机的正常运行。
meg采用Go语言开发,并且不需要其他运行时依赖,因此我们首先需要在本地设备上安装并配置好Go v1.9+环境。接下来,我们就可以使用下列命令来安装meg了:
▶ go install github.com/tomnomnom/meg@latest
除此之外,我们还可以直接访问该项目的【Releases页面:https://github.com/tomnomnom/meg/releases】来下载预编译的工具版本,并将工具路径存储到$PATH中(例如/usr/bin/)。
如果你遇到安装错误问题,可能是因为你的Go环境版本太低,可以尝试使用下列方法解决:
# github.com/tomnomnom/rawhttp
/root/go/src/github.com/tomnomnom/rawhttp/request.go:102: u.Hostname undefined (
type *url.URL has no field or method Hostname)
/root/go/src/github.com/tomnomnom/rawhttp/request.go:103: u.Port undefined (type
*url.URL has no field or method Port)
/root/go/src/github.com/tomnomnom/rawhttp/request.go:259: undefined: x509.System
CertPool

我们可以给工具提供一个包含路径的列表文件:
/robots.txt
/.well-known/security.txt
/package.json
或者提供一个包含主机地址的列表文件:
http://example.com
https://example.com
http://example.net
接下来,meg将对每一台主机中的每一个地址发送请求:
▶ meg --verbose paths hosts
out/example.com/45ed6f717d44385c5e9c539b0ad8dc71771780e0 http://example.com/robots.txt (404 Not Found)
out/example.com/61ac5fbb9d3dd054006ae82630b045ba730d8618 https://example.com/robots.txt (404 Not Found)
out/example.net/1432c16b671043271eab84111242b1fe2a28eb98 http://example.net/robots.txt (404 Not Found)
out/example.net/61deaa4fa10a6f601adb74519a900f1f0eca38b7 http://example.net/.well-known/security.txt (404 Not Found)
out/example.com/20bc94a296f17ce7a4e2daa2946d0dc12128b3f1 http://example.com/.well-known/security.txt (404 Not Found)

工具会将所有的数据输出结果存储在一个名为./out的目录中:
▶ head -n 20 ./out/example.com/45ed6f717d44385c5e9c539b0ad8dc71771780e0
http://example.com/robots.txt
> GET /robots.txt HTTP/1.1
> Host: example.com
< HTTP/1.1 404 Not Found

如果没有提供任何运行参数的话,meg将会从一个名为./paths文件中读取路径,并从名为./hosts的文件中读取目标主机,而且不会提供任何输出:
▶ meg
但结果会存储在名为./out/index的索引文件中:
▶ head -n 2 ./out/index
out/example.com/538565d7ab544bc3bec5b2f0296783aaec25e756 http://example.com/package.json (404 Not Found)
out/example.com/20bc94a296f17ce7a4e2daa2946d0dc12128b3f1 http://example.com/.well-known/security.txt (404 Not Found)

我们可以使用这个索引文件来寻找响应信息的存储位置,可以直接使用grep来快速查找:
▶ grep -Hnri '< Server:' out/
out/example.com/61ac5fbb9d3dd054006ae82630b045ba730d8618:14:< Server: ECS (lga/13A2)
out/example.com/bd8d9f4c470ffa0e6ec8cfa8ba1c51d62289b6dd:16:< Server: ECS (lga/13A3)
(向右滑动,查看更多)
如果你想要请求一个路径,可以直接以参数形式指定:
▶ meg /admin.php
下面给出的是meg工具的详细帮助信息:
▶ meg --help

-H, --header <header> 发送一个自定义HTTP Header
-r, --rawhttp 使用rawhttp库发送请求
-s, --savestatus <status> 仅存储指定状态码的响应信息
-v, --verbose Verbose模式
-X, --method <method> 使用的HTTP方法,默认使用Get方法
