DAV TryHackMe

 Introduction




1) Port Scan



as usual, as the http is open, we go to the web browser and see what is in there. Don't forget to see the source code to see if there is anything interesting. 


as we inspect, there is nothing we can find. 

2) Directory scan

let's see if there is any directory that we can acces


as we go to the /webdav, it prompt us with username and password

3) Cadaver




as we search on the internet, we can see there is a default credential for this "dav"


there is a hash given under one of the directory, but sadly I can't crack it. 



alternatively, I dig around google and find this.

which means I can use cadaver command for my next step. 


as we can see here, there is a "put" command which we can use to upload a file, which is a "shell" from our own machine to the webdav.



4) Reverse shell

go to revshells.com to create our own reverse shell


copy it and paste it on a document created on our machine. 





as you can see we successfully upload it on webdav. 



Now make sure that our machine is listening using command below. 


as we go back to the browser and execute the shell

and here it contact back to it.


as usual I get around the directories, and finally find the first flag.


5) Elevate/upgarde the shell

Now we need to elevate the shell using command below



to search for the root flag, first let's see what we can do as a root. 

here we can see that we can concantenate any file based on the output.


based on boot2root ctf category the root.txt file usually placed under the root directory. 

and yes, we get our root flag

Data Exfiltrtation Detection (DNS, FTP, HTTP, ICMP)

Image
Learning Objectives In this entry, we will cover the following learning objectives: - Understand the common methods used for data exfiltration. - Learn how to detect exfiltration attempts using network traffic analysis. - Identify signs of exfiltration on endpoint devices. - Correlate logs in a SIEM to uncover hidden exfiltration channels. 1) Data Exfil: Overview Tech, and indicators -> unauthorized data transfer from in to out by adversaries -> can be by insider or malware 1.1) Why they do data exfil?  Reason Description Financial Gain Stolen data (e.g., credit card information, personal records) can be sold on the dark web or used for fraud. Espionage Nation-state actors target intellectual property, trade secrets, or classified information for strategic advantage. Ransomware & Extortion Attackers steal data and threaten to leak it unless a ransom is paid. Disruption & Sabotage Adversaries aim to damage an organization's reputation or operations by exposing sensitiv...

Firewall, WAF, and VPN manual log Analysis using command line.

Image
Incident Scenario Initech Corp, a mid-sized financial services company, has recently deployed a new firewall and intrusion detection system (IDS) to monitor its network perimeter. Over the past month, security analysts have noticed abnormal traffic patterns, but the SOC team has been overwhelmed and missed deeper analysis. As a new security analyst, you have been tasked with reviewing one month of perimeter logs to determine what techniques the adversary used, and whether they succeeded in breaching the perimeter. You have been given three sets of logs from the time of the incident. The logs can be found in the Perimeter_logs/challenge directory on the Desktop. Firewall Logs:firewall.log WAF Logs:ids_alerts.log  VPN Logs:vpn_auth.log  LOG ANALYSIS Let's start by exploring the logs, as shown below: Commandline: head firewall.log Explore ids logs, as shown below: Commandline: head ids_alerts.log Examine VPN Logs, as shown below: Commandline: head vpn_auth.log Reconnaissance atte...

Reversing ELF TryHackMe

Image
  1) crackme1 for the first challenge all we need to do is run the file named "crackme1" and we got the flag. 2) crackme2 when we try to run the file, it correct us and say the right usage is ./crackme2 + password, and we need to find this password. As we open the file in ghidra, we can see if we use "super_secret+password" it will give us access granted as the output. and as we suspected, once we use it as the password, it will give us the flag.  3) crackme3 The same case as crackme2, so first let's see if there is any interesting strings that we can see.  here we can see there is a base64 strings as we open the file in ghidra, it says that if we input the base64 strings as the password, then the password is correct.  so we decode the strings first and then use it as the password.  4) crackme4 This launches GDB (GNU Debugger) and loads the executable crackme4. This tells GDB to print all the functions found inside the binary. This lets you identify where the re...
