Once the host was identified, Nmap, a port scanning tool, was used to discover which services were running on the machine. The scan revealed port 80 (HTTP), 22 and 3000 were opened.

TOR WEB BROWSER

  TOR WEB BROWSER TOR INSTALLATION First of all; we're going to this link from the oficial webpage: https://www.torproject.org/es/download/   where we have to download this version our laptop, Windows and Linux but in my case I've had to download for Windows 10. When the program is installed we will press execute and we'll follow step by step:   We'll open and we'll see this image where you have to select the language and select ok to continue the instal l ation. In addition, we'll select the location wherever you want install the program, but in my case I prefer the default location and you'll able to select wherever you want. Now, we will be started the installation process and when it finished you will be able to see the picture below: TOR CONNECT If the process has been successful, you will be able to connect with the connect button which you can observe in both pictures below: ADD A BRIDGE ...

ACTIVEDIRECTORY (TRYHACKME) First of all, let’s go to execute nmap toolkit and we'll be able to start the enumeration of the ports as you can see below with this command: sudo nmap -n -Pn -p- --min-rate 5000 10.10.135.154 -vvv -sC -sV This revealed several open TCP ports with associated services, including: DNS (53),  HTTP  (80),  Kerberos (88),  RPC (135),  NetBIOS-SSN (139),  SMB (445),  RDP (3389),  WS-Management (5985)  LDAP (389, 636, 3268, 3269) Moreover, service and NSE script detection provided valuable information about the services running on these ports, such as IIS 10.0, Microsoft Windows Kerberos , Active Directory LDAP , and Microsoft Terminal Services . The SSL/TLS certificate information on port 3389 indicated the common name AttacktiveDirectory.spookysec.local, reinforcing the target as an Active Directory server. rdp-ntlm-info also provided details about the domain (THM-AD) and computer name (ATTACKTIVEDIREC) as you can se...

  PICKLE RICK I'm going to realize the resolution of the machine Level Easy from Tryhackme called  Pickle Rick  which is a machine so easy to realize. First of all,  we can observe that in the picture bellow we have some inforamtion and I'm going to execute control +u  and we can see in the second picture below that we've obtained a  Username. I'm going to gathering information about machine and I have to enter in the Linux terminal and I must introduce this command which you canobserve in the picture below:   gobuster dir -u(url) http://10.10.99.188/ -w(password dictionary)  /usr/share/wordlist/dirb/common.txt -x (formato que quereos que busque) .txt*, .php, .login,  In this case, we can observe that scan has discovered this 4 webpages: /assests /denied.php /index.html /login.php /robots.txt Now, we can see such as the web page from /robots.txt   it seems the password in the picture below.

RHOSTS :This I've set up the IP Address which I am finding out that in my case is 192.168.100.0/24 (all the IP Address from network that could be possible which I am analyzing).

BUSCALOVE First of all, I am going to do this machine from cybersecurity labs called BuscaLove which is easy Level. For it, let’s go to open Linux terminal and we have to write the command when we can see in the picture below. cd Descargas In addition, we have to depress the unzip file whose name’s buscalove.zip you can see in the picture below. Now we have to deploy the vulnerability machine whose command is sudo bash auto_deploy.sh buscalove.tar we can see in the picture below. On the other hand, to start the attack at virtual machine, we must verify if the attacker machine is in the same range of IP Address and we have to introduce this command which is ping -c 3 172.18.0.2 we can see in the picture below. As I,ve just seen the IP Address it’s in the same range of my IP Address we have to introduce the command with nmap tool which is nmap -n -Pn 172.18.0.2 -p- - -min-rate 4000 -vvv( here you can see in this picture the scanner) but I’ve got it 2 ports: 22: open ssh 80: open http No...

Firstly; we have to open a new Shell terminal in our virtual machine and we have to execute this command you can see in the picture below which we'll be able to do the port scans. In addition, as we know the open ports we’re going to use this param  -A ( user scripts from Nmap to look at vulnerabilities)  and  sV  which it will give if it’s possible versions in each ports you want to analyze in the four pictures you can observe below.
