test_virus.c

代码给出了Linux系统下蠕虫代码如何通过有漏洞的系统进行蔓延的。

/* Simple file opening and closing program
* to test Vscr2 virus spread to another machine
*
* If a file does not exist, it will create it.
*  
* This program should be compiled after the virus
* has been executed on the system.
* When it is compiled, the functions from the corrupted
* stdio.h will be pasted into the code.
*
* Then, once the compiled version is run on another 
* machine, it will infect that machine.
