In this lecture, we are going to perform the aggressive scan.
Aggressive scan is extension of SUY or service aversion scan that we performed in the last lecture.
Aggressive scan not only scans for services and their versions, it also tries to figure out the operating
system of the target machine, runs TRACEROUTE and provides some additional useful information as well.
Now type sudo this time we have to run and map as a route user and if you are on windows then open command
prompt as administrator.
So type and map hyphen uppercase e.
Now write a domain name or IP address hyphen a means aggressive.
It scans the target network aggressively.
It tries to gather as much information as possible about the target system.
Therefore, this scan takes time to complete.
So wait patiently.
Now type your password.
All that guys scan is complete.
We have a plenty of information to dissect.
Aggressive scan displays the service version just like the as we scan.
Right.
As you can see, we have the current version of search, which is 6.61.
Then we have SSH host keys.
These are basically public encryption keys used in asymmetric encryption.
You can't read much from these public keys.
Then we have a version of Apache Web Server, which is 2.4.7.
We also have information of the target operating system.
As you can see, operating system of target is Linux and at the end we have traceroute information,
aggressive scan runs the traceroute in the background.
Traceroute basically displays the route or path that the packets have to take to reach the destination.
Packets have to travel through multiple routers or hops to reach the destination.
Right and trace route basically lists the exact routers or hops along with their IP addresses that the
data has to go through to reach the destination.
As you can see, packets sent from my computer to and map server went through four hops to reach the
destination or and map.
