Hack The Box Sick Teacher

This time back with Hackthebox challenge !!
Downloaded the file on clicking the download button and already mentioned that password for
Zip file is hackthebox


This is the txt file I got inside zip file


Stuck at this??
This is substitution cipher
Your Question - How I got to know about it ?
My answer - You have to understand the background concept of crypto before indulging yourself
In it and making your hands dirty!!
         Every letter is replaced by any random letter and this is known as substitution.
Note: Like in mathematics , if we replace one value with another we say it a substitution
So same concept is working here .


So , pretty obvious that once I know what type of cipher it is , I will search for substitution solver
Results :  This is the link of the solver https://www.guballa.de/substitution-solver
Provided the input in the box


Here is the decoded result .


Flag : LOREMIPSUMDOLORSITAMET

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 but the hint was already on th
