00:00.150 --> 00:04.360
In this lecture, we are going to perform the aggressive scan.

00:04.770 --> 00:14.040
Aggressive scan is extension of SUY or service aversion scan that we performed in the last lecture.

00:14.070 --> 00:23.460
Aggressive scan not only scans for services and their versions, it also tries to figure out the operating

00:23.460 --> 00:32.130
system of the target machine, runs TRACEROUTE and provides some additional useful information as well.

00:32.160 --> 00:43.230
Now type sudo this time we have to run and map as a route user and if you are on windows then open command

00:43.230 --> 00:45.450
prompt as administrator.

00:45.450 --> 00:49.050
So type and map hyphen uppercase e.

00:49.290 --> 00:55.800
Now write a domain name or IP address hyphen a means aggressive.

00:55.830 --> 00:59.640
It scans the target network aggressively.

00:59.640 --> 01:06.660
It tries to gather as much information as possible about the target system.

01:06.660 --> 01:10.800
Therefore, this scan takes time to complete.

01:10.800 --> 01:12.840
So wait patiently.

01:13.440 --> 01:15.060
Now type your password.

01:15.540 --> 01:17.700
All that guys scan is complete.

01:17.700 --> 01:21.330
We have a plenty of information to dissect.

01:21.690 --> 01:28.530
Aggressive scan displays the service version just like the as we scan.

01:28.530 --> 01:28.920
Right.

01:28.920 --> 01:35.220
As you can see, we have the current version of search, which is 6.61.

01:35.430 --> 01:38.460
Then we have SSH host keys.

01:38.460 --> 01:44.670
These are basically public encryption keys used in asymmetric encryption.

01:44.910 --> 01:49.560
You can't read much from these public keys.

01:49.590 --> 01:55.410
Then we have a version of Apache Web Server, which is 2.4.7.

01:55.410 --> 02:00.420
We also have information of the target operating system.

02:00.420 --> 02:09.750
As you can see, operating system of target is Linux and at the end we have traceroute information,

02:09.750 --> 02:13.950
aggressive scan runs the traceroute in the background.

02:14.100 --> 02:23.760
Traceroute basically displays the route or path that the packets have to take to reach the destination.

02:23.760 --> 02:30.780
Packets have to travel through multiple routers or hops to reach the destination.

02:30.780 --> 02:40.770
Right and trace route basically lists the exact routers or hops along with their IP addresses that the

02:40.770 --> 02:45.090
data has to go through to reach the destination.

02:45.090 --> 02:54.870
As you can see, packets sent from my computer to and map server went through four hops to reach the

02:54.870 --> 02:56.730
destination or and map.
