QQ（3902648776）Telegram/飞机号（Xue5789）SQL注入漏洞：攻击者通过输入恶意SQL代码非法访问数据库。在表单等输入框中注入语句，可绕过认证授权，获取、更改、删除敏感数据。危害：1. 窃取数据：用户名、密码、支付信息等敏感数据被盗。2. 破坏数据：删除、更改数据库内容，导致服务中断。3. 破坏系统：执行攻击代码，威胁服务器稳定性。防范措施：1. 使用参数化SQL查询（预编译语句）。2. 过滤用户输入，校验特殊字符。3. 采用安全编程语言（Java、Python、PHP等）。4. 定期更新应用，修复漏洞。5. 加密数据和系统文件。
总结：SQL注入威胁严重，需选择开发语言、更新系统、过滤输入、加密数据。提高安全意识，源头预防。注入手法灵活，需构造巧妙语句获取数据。防火墙难察觉，需查看日志。SQL注入其实就是恶意用户通过在表单中填写包含SQL关键字的数据来使数据库执行非常规代码的过程。1.永远不要信任用户的输入。对用户的输入进行校验，可以通过正则表达式，或限制长度；对单引号和双"-"进行转换等。2.永远不要使用动态拼装sql，可以使用参数化的sql或者直接使用存储过程进行数据查询存取。3.永远不要使用管理员权限的数据库连接，为每个应用使用单独的权限有限的数据库连接。4.不要把机密信息直接存放，加密或者hash掉密码和敏感的信息。

In a world reshaped by the dawn of Quirks-extraordinary superhuman abilities-the first spark of change came in the Chinese city of Qing Qing, where a child radiated light from their body. From that moment, humanity began evolving in unprecedented ways, with nearly 80% of the population manifesting powers that ranged from the miraculous to the bizarre. Society adapted, forming a new superhuman structure where Pro Heroes stood as paragons of hope and justice, battling villains who sought to exploit their gifts. But in this vibrant world of heroes, not all powers were created equal. Arashi Nakamura was born into a modest family, and is part of the dwindling 20% of humanity believed to be powerless. For years, he accepted his fate, resigned to a life in the shadows of larger-than-life heroes like All Might. Arashi admired them but understood that without a Quirk, he could never stand among them.

True Magician by dbelphegor

Waking up in the body of a Romani Archiman is acceptable. Getting 3rd and 1st True Magics is nice. Getting Beasts as pets - delightful. The world of DxD is unforgivable. It's a world where some teenagers who aren't even two decades old somehow mystically defeat the descendants of legendary heroes, ancient demons, powerful dragons, etc. Why does this happen? Simply because! Simply put, this world only makes sense because it doesn't. And now, I have to put up with the fact that I live here. Such pain. (DxDxMulti)
