fix: corrected attack condition

There was a syntactic error in the condition (due to lack of Module documentation :/). This has been corrected to attack on SYN packets only
re-added send() command

I initially removed the send() command in belief that the newly constructed packets were being sent twice (once upon creation, another upon calling of send()). I now realize that the two packets were not mine. one was mine. another was from the localhost system.
