這篇文章主要介紹了記一次mysql5.7測試數(shù)據(jù)庫被刪表的問題,具有很好的參考價值,希望對大家有所幫助,如有錯誤或未考慮完全的地方,望不吝賜教
問題描述
為了方便臨時測試，就用docker啟動了一個mysql容器，插入了一些測試數(shù)據(jù)，用完之后端口（3306）忘了沒有關(guān)掉，被攻擊刪表（省的我自己刪了，哈哈），雖然是無用的數(shù)據(jù)，多少是個教訓(xùn)。
詳情如下
多了一個README_ADK庫，庫下一張README表，被刪的庫下表都被刪，多了一張README表
內(nèi)容如下
mysql> select * from README\G;
*************************** 1. row ***************************
id: 1
readme: 以下數(shù)據(jù)庫已被刪除：blog, demo, school。 我們有完整的備份。 要恢復(fù)它，您必須向我們的比特幣地址bc1qvrgtzc06w2rjdfx8p9u789edw56dj8ffqvrcr5支付0.0075比特幣（BTC）。 如果您需要證明，請通過以下電子郵件與我們聯(lián)系。 shao58@tutanota.com 。 任何與付款無關(guān)的郵件都將被忽略！
BTC_address: bc1qvrgtzc06w2rjdfx8p9u789edw56dj8ffqvrcr5
email: shao58@tutanota.com
分析
從日志里分析，就是反復(fù)拿IP去嘗試：

185.156.72.10 62.33.81.189 45.83.65.52 220.121.127.64
最后使用220.121.127.64嘗試密碼，賬號無非也就這幾個：root、admin、dbuser

總結(jié)
數(shù)據(jù)庫可以避免%用戶，若需要%用戶，可避免這幾個用戶名，密碼盡量復(fù)雜（https://suijimimashengcheng.bmcx.com隨機密碼，避免密碼：root,admin,123此類的易出現(xiàn)的密碼）。
端口可以加指定白名單訪問，常用的端口可以用別的端口替代，如22端口用8822，3306用13306代替等。
以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持腳本之家。
