Scanning Phase


To know the IP of the target machine we have to scan the network on which target is connected in my case its my local network
Command to scan the local network : arp-scan --local
Victim IP : 192.168.43.136


Now proceeding in scanning phase using nmap
I enumerated info using nmap aggressive scan with ping sweep
Command : nmap -A 192.168.43.136 -Pn
Results : nfs server is active so i tried to gain access to the server.


Gaining access to server as it is open
Command : showmount -e 192.168.43.136
Results : it has the content in /shared and open to everyone




Now i want to see the content of the server so i decided to make directory on my desktop named as Paras so that i can mount the content in this folder
Command : cd Desktop (to change my dir location to Desktop)
Command : mkdir Paras (to make new dir)
Command : mount -t nfs 192.168.43.136:/shared /root/Desktop/Paras
(to mount the content from shared to new dir i.e Paras which is located in /root/Desktop)
To confirm whether the content is copied in Paras or not i just navigate to Paras and list the contents.
Command : ls (to list the content of the dir)
Result : found 2 directories named USB and whoami and 1 .img file




Then i mounted .img file in USB folder to read the contents of the file
Command : mount USB-stick.img USB
Then after navigating to USB folder and on listing the contents i found image files in different formats .
Command : ls (to list the contents)
Result : found image files which are of no use to me




So finally mounted the content from server to whosmi folder present in Paras and explored the content further to get the flag
Command : mount -t nfs 192.168.43.136:/ whoami
Result : i got few folders and one of them is root folder
After navigating to root folder i got the flag as proof.txt and obtained the flag
Command : cat proof.txt (to read the flag)

TryHackme: Blue Walkthrough

Task 1: Recon After we've connected to the tryhackme network the first task is to enumerate the target. We use Nmap for scanning the target IP. Command Used : nmap -sS -Pn <target-ip> -sS : Scan using TCP SYN scan -Pn : Treats all host as online --skip host discovery Next we used a command to find the vulnerability on the target machine. Command Used : nmap --script vuln <target-ip> --script : Specify the --script option to choose your own scripts to execute by providing categories , script file names, or the name of directories full of scripts you wish to execute. vuln : These scripts check for known vulnerabilites and generally only report results if they are found. Below, we see that nmap is indicating the target may be vulnerable to ms17-010(on the left0 and we can verify this using metasploit. To start Metasploit use command "msfconsole" We start by simply doing a search for ms17-010 Here we use module 2 i.e. exploit/windows...

HackTheBox-Traceback Walkthrough

I started with scanning the IP Addr with nmap using the simple command. Command Used: nmap IP Addr of machine -Pn  nmap 10.10.10.181 -Pn  Starting Nmap 7.80 ( https://nmap.org ) at 2020-04-15 02:27 IST Nmap scan report for 10.10.10.181 Host is up (0.18s latency). Not shown: 998 closed ports PORT   STATE SERVICE 22/tcp open  ssh 80/tcp open  http Now only two things were in my mind and those were what should I enumerate first ssh or http. SSH can only be bruteforced and this point and bruteforce on the online machine doesn't works or we can say that most online hosted machines are not made to be bruteforced. So, I started  with HTTP. I fired up directory burster to find juicy directories if any and mean while I decided to browse the IP Addr since HTTP Service is active and running. I was presented with the below screen  dirb was not able to find any directories ...
