Carberp源代码泄露后续——黑掉黑客
上周，价值连城的银行盗号软件Carberp源代码遭泄露，高达1.8个G的数据，全球同行都在纷纷研究它的恶意代码。然而，一位法国的安全研究人员Steven K发现了独特的东西。他发现了Carberp自身的控制台存在很多安全漏洞。其中包括IP地址欺骗和远程代码控制。
研究人员发现了Carberp’s Panel中“data”这个变量存在远程代码执行漏洞，如下图所示：
IP地址欺骗漏洞：
同时他还写了PoC：

他已经成功利用漏洞攻陷了数据的用户名、密码、Auth Key。如下图所示：
换句话说，可以利用这个漏洞去“坐享其成”，把使用Carberp的黑客黑掉，摘取黑客的革命成果。
