Metasploit Revealed: Secrets of the Expert Pentester

Decision-making operators

Decision-making is also a simple concept as with any other programming language. Let's have a look at an example:

    irb(main):001:0> 1 > 2
    => false

Let's also consider the case of string data:

    irb(main):005:0> "Nipun" == "nipun"
    => false
    irb(main):006:0> "Nipun" == "Nipun"
    => true

Let's consider a simple program with decision-making operators:

def find_match(a) 
if a =~ /Metasploit/ 
return true 
else 
return false 
end 
end 
# Main Starts Here 
a = "1238924983Metasploitduidisdid" 
bool_b=find_match(a) 
print bool_b.to_s 

In the preceding program, we used the word "Metasploit" which sits right in the middle of junk data and is assigned to the variable a. Next, we send this data to the find_match() method, where it matches ...
