被动指纹（Passive）

  • 不请求： 不写request结构
  • / 请求， 无其它额外设置
request:
  cache: true
  method: GET
  path: /
  • icon： 使用 getIconContent 函数

​
主动指纹（Active）

除被动指纹外的情况都属于主动指纹

​
通过 ICON HASH 匹配

建议规则名称：favicon_hash

​
便捷计算icon hash的方式

将下列代码放入powershell中运行，请确保你对应版本的python有安装requests，mmh3包
function Get-IconHash {
param(
    [string]$url
)
python -c "import requests,sys,mmh3,codecs;print('icon_hash=' + str(mmh3.hash(codecs.lookup('base64').encode(requests.get('$url').content)[0])))"
}
使用示例：
Get-IconHash 'https://www.baidu.com/favicon.ico'

# 运行结果
icon_hash=-1588080585

​
使用内置函数自动搜索 ICON 路径

rules:
  favicon_hash:
    request:
      method: GET
      path: /
    expression: |-
      faviconHash(response.getIconContent()) == 149371702

​
自定义 ICON 路径

rules:
  favicon_hash:
    request:
      method: GET
      path: /not_normal_favicon_path.ico
    expression: |-
      faviconHash(response.body) == 149371702

  kw_in_body:
    request:
      method: GET

  expression: |
    "server" in response.headers && response.headers["server"].contains("nginx")
  output:
    version: |
      "^nginx/(?P<version>.*)$".submatch(response.headers["server"])["version"]
