<p>以前也关注过各种比特币勒索，对于oracle数据库主要集中在<a href="//www.xifenfei.com/2016/11/plsql-dev-hacker-bitcoin.html" title="plsql dev引起的数据库被黑勒索比特币实现原理分析和解决方案" target="_blank">pl/sql dev</a>和<a href="//www.xifenfei.com/2016/11/your-files-are-encrypted-recovery.html" title="YOUR FILES ARE ENCRYPTED!—ORACLE比特币勒索恢复支持" target="_blank">文件加密</a>勒索,以前不管哪种勒索都没有这次的波及的范围只广,影响之大.就连天朝的公安网都严重感染,很多部门业务无法正常情况.<br />
<strong>感染之后现象</strong><br />
<a href="//www.xifenfei.com/2017/05/wncry-recovery.html"><img src="//www.xifenfei.com/wp-content/uploads/2017/05/btb1.jpg" alt="btb" width="815" height="563" class="alignleft size-full wp-image-7096" /></a><br />

<hr />
这里可以发现这次的比特币加密是有选择性的加密,不是所有文件都加密,而是根据文件后缀名来判断,然后给予加密勒索.<br />
<strong>查看加密后文件</strong><br />

<hr />
这次的故障和以往的加密勒索不一样,这次是整个文件全部加密,和以往的加密区别挺大的,因为是全文加密也给恢复带来了非常大的难度.<br />
<br />
<strong>收到比特币</strong></p>

<p>这个链表你可以发现.利索人收到大量比特币,一般不建议交比特币:1)助长了这种气焰,2)交钱也不一定可以解密(身边有失败的例子)<br />

<hr />
比较侥幸，我们虽然无法解密该加密文件,但是根据加密原理,在硬盘上运行过oracle(存放过oracle数据文件),那就在硬盘上面有痕迹,只要这个痕迹没有覆盖掉,我们就可以通过底层扫描block恢复出来其中的数据(类似:<a href="//www.xifenfei.com/?p=5249" title="asm 加磁盘导致磁盘组损坏恢复" target="_blank">asm disk header 彻底损坏恢复</a>).通过这个原理,我们今天顺利恢复了一个客户的数据库.如果这个方面无法自行恢复的,可以联系我们给予技术支持<br />

由于技术功底有限,目前我们只能对于数据库被加密勒索比特币的进行恢复,其他文件无法恢复.对于数据库,我们也需要评估现场之后才能确定是否可以恢复.</p>
