<h3 class="title"><i class="fa-solid fa-book"></i> 比赛介绍</h3>
<h3>DUTCTF为大连理工大学信息安全竞赛创新实践能力赛，于每年3月份举办，能力赛由大连理工大学，中共市委网信办主办，由大连理工大学信息与通信工程学院，大连市网络空间安全重点实验室承办，由大连理工大学软件学院创新创业中心螺丝工作室提供竞赛技术支持，面向具有正式学籍的，大连理工大学各专业各年级在读的全日制本科生、预科生。⽐赛采取线上CTF解题形式,由组内人员策划、运维、命题，旨在普及网络安全知识、激发网络安全兴趣。</h3>
<h3 class="title"><i class="fa-solid fa-cubes"></i> 题目介绍</h3>
<h3>1.主要含有五大方向，Web(网站渗透攻防)、Pwn(二进制漏洞利用)、Reverse(逆向工程)、Misc(安全杂项)、Crypto(密码学)</h3>
<h3>2.目的是获得题目中的flag，flag通常为一段有意义字符串，例如：DUTCTF{N1c3_to_m3et_y0u_In_DUTCTF2024}</h3>
<h3>3.题目动态分数初始值1000分，随解题人数增加而递减，设置一二三血，有额外积分加成，后续按题目实际分数赋值。</h3>
