在过去的这么多年里，黑客与黑客之间一直存在争论。这两个术语都与一个主题相关，即“黑客”。
骇客：
黑客可以定义为为获得对未授权系统的访问而进行的技术或计划。简单地说，我们可以说是出于非法目的而访问网络或计算机。做到这一点的人非常聪明，并且精通计算机。
擅长黑客技术的人分为两类：
- 骇客：
黑客是善良的人们，他们出于良好的目的进行黑客攻击并从中获取更多知识。他们通常会在系统中发现漏洞，并帮助他们覆盖漏洞。黑客通常是程序员，他们获得有关操作系统和编程语言的高级知识。这些人绝不会损坏或损害任何类型的数据。 - 饼干：
破解者是一种坏人，他们出于恶意破坏或窃取数据的目的而远程破坏或破坏系统或计算机。黑客通过获得对网络的未授权访问来破坏数据。作品在从事非法活动时总是被隐藏起来。绕过计算机和社交媒体网站的密码，可以窃取您的银行详细信息并从银行转账。
黑客和饼干之间的区别：
