【Python安全攻防】【网络安全】一、常见被动信息搜集本领
一、IP查询
原理
:通过目标URL查询目标的IP地址。
所需库
:
socket
Python代码示例:
import socket
ip = socket.gethostbyname('www.163.com')
print(ip)
复制代码
上述代码中,使用
gethostbyname
函数。该函数位于Python内置的socket库中,其原型如下:
def gethostbyname(host): # real signature unknown; restored from __doc__
"""
gethostbyname(host) -> address
Return the IP address (a string of the form '255.255.255.255') for a host.
"""
pass
复制代码
参数host为目标的URL,返回对应的ip地址。
示例代码输出:
125.39.47.211
Process finished with exit code 0
复制代码
二、Whois查询
原理
:用来查询域名是否已经被注册,以及注册域名的具体信息。
所需库
:whois
安装whois模块:
pip install python-whois
复制代码
记录
执行上述命令后,导入会报错(找不到Whois模块)(在PyCharm中,IDLE则未出现此问题),需要在报错处再次执行安装命令。另一个方法是在终端中直接执行安装命令,并在IDLE中运行代码:
Python代码示例:
from whois import whois
data = whois("www.163.com")
print(data)
复制代码
示例代码输出(含注释阐明):
{
"domain_name": [ # 域名:163.com
"163.COM",
"163.com"
],
"registrar": "MarkMonitor Information Technology (Shanghai) Co., Ltd.", # 注册公司

}

三、子域名挖掘
通过必应(必应搜刮引擎)举行子域名搜集:
起首确保安装有requests库、bs4库、urllib库,安装这些库的命令和过程如下:
Python代码示例:
import requests
from bs4 import BeautifulSoup
from urllib.parse import urlparse
import sys
def bing_search(site, pages):
Subdomain = []
headers = {"User-Agent": "Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0",
"Accept": "text/html,application/xhtml+xml, application/xml;q=0.9,*/*;q=0.8",
"Referer": "https://cn.bing.com"
}
for i in range(1, int(pages)+1):
url = "https://cn.bing.com/search?q=site%3a"+site+"&go=Search&qs=ds&first="+ str((int(i)-1) * 10) + "&FROM=PERE"
html = requests.get(url, headers=headers)
soup = BeautifulSoup(html.content, 'html.parser')
job_bt = soup.findAll('h2')
for i in job_bt:
link = i.a.get('href')
domain = str(urlparse(link).scheme + "://" + urlparse(link).netloc)
if domain in Subdomain:
pass
else:
Subdomain.append(domain)
print(domain)
if __name__ == '__main__':
if len(sys.argv) == 3:
site = sys.argv[1] # 参数1:网址
page = sys.argv[2] # 参数2:获取搜索引擎页数
else:
print("usage: %s baidu.com 10" % sys.argv[0])
sys.exit(-1)
Subdomain = bing_search(site,page)
复制代码
对域名baidu.com举行子域名网络,获取50页搜刮结果:
