对于这类情况类似以前处理的case：
read_me_recover_tn勒索恢复
RECOVER_YOUR_DATA勒索恢复
A____Z____RECOVER____DATA勒索恢复
处理方法一般也就是先考虑os层面恢复,如果os层面无法恢复,就从block层面进行恢复,这个客户通过最终分析,恢复出来客户需要的表数据

对于类似这种A_H_README_TO_RECOVER勒索恢复,建议先对系统进行镜像或者快照,然后按照先os层面恢复,在block级别恢复的方法处理,如果无法自行解决,可以联系我们进行技术支持,最大限度抢救和数据,减少损失

另外建议加强系统和mysql安全加固,数据库尽量不要暴露在公网上

read_me_recover_tn勒索恢复

发表于 2024 年 5 月 10 日 由 惜分飞

最近有客户被MySQL删库勒索,现象如下:
1. 删除掉以前的库,并创建一个同名库,并且会创建一个read_me_recover_tn库,类似下图:
readme_to_recover_tn

2. 在read_me_recover_tn库中有一个readme表,每个被删除然后创建的库里面也有一个readme表
readme.ibd
20240510003427
3. 每个readme表内容类似信息类似:

mysql> desc readme
    -> ;
+-----------------+------+------+-----+---------+-------+
| Field           | Type | Null | Key | Default | Extra |
+-----------------+------+------+-----+---------+-------+
| id              | int  | NO   | PRI | NULL    |       |
| Message         | text | YES  |     | NULL    |       |
| Bitcoin_Address | text | YES  |     | NULL    |       |
+-----------------+------+------+-----+---------+-------+
3 rows in set (0.01 sec)

mysql> select * from readme\G;
*************************** 1. row ***************************
             id: 1
        Message: I have backed up all your databases. To recover them you must
 pay 0.008 BTC (Bitcoin) to this address: 15f9vdGBeT1NCMp6z9NxrQEEUxnYqRPvyC . 
Backup List: xxxx_db, xxxx_db_test. After your payment email me at 
dbrestore3195@onionmail.org with your server IP (xx.xx.xx.xx) and transaction 
ID and you will get a download link to your backup. Emails without transaction 
ID and server IP will be ignored.
Bitcoin_Address: 15f9vdGBeT1NCMp6z9NxrQEEUxnYqRPvyC
1 row in set (0.00 sec)

这类勒索和我以前介绍相关文章类似:
RECOVER_YOUR_DATA勒索恢复
A____Z____RECOVER____DATA勒索恢复

处理办法也完全相同:
建议先对系统进行镜像或者快照,然后按照先os层面恢复,在block级别恢复的方法处理,如果无法自行解决,可以联系我们进行技术支持,最大限度抢救和数据,减少损失
