最近遇到几个mysql数据库被黑客删除库,并且留下比特币勒索信息在每个库的WARNING表中

mysql> desc WARNING

大概的意思就是:我们已经把你的数据库备份,您交给我们0.06个比特币,我们把数据给你,如果10天之内我们没有收到款,即将把数据库给公开或者作为其他用途.根据我们以往接触的朋友经验,付款之后数据库也不会给你(很可能黑客根本就没有备份数据库,只是删除了数据库然后勒索比特币.

对于这类情况,通过分析,确认黑客是删除了数据库,在没有覆盖的情况下,我们可以对其数据进行恢复,处理类似:MySQL drop database恢复(恢复方法同样适用MySQL drop table,delete,truncate table)最大限度缓解因为数据库被破坏带来的损失.

如果您也遭遇到该问题,请保护现场,不要导入备份数据库,不要对数据所在分区进行写操作(现场保护的越好,数据恢复效果越好),对相关磁盘进行镜像,防止二次破坏.我们可以提供专业的mysql恢复服务,为您减少损失.
