hping3 -- SYN flood attack


Step 1: use reconnaissance to find victim. I use zenmap to find the victim, it's my boyfriend. 😆.


24 means find all the subnet in the segment.
This is equal to the command: nmap -T4 -A -v 192.168.3.16/24


I found there are two apple machines, one is his, the other is mine. 


His IP is 192.168.3.11

Step 2: do SYN flood attack with hping3 



We’re sending 15000 packets (-c 15000) at a size of 120 bytes (-d 120) each. We’re specifying that the SYN Flag (-S) should be enabled, with a TCP window size of 64 (-w 64). To direct the attack to our victum’s HTTP web server we specify port 80 (-p 80) and use the --flood flag to send packets as fast as possible. As you’d expect, the --rand-source flag generates spoofed IP addresses to disguise the real source and avoid detection but at the same time stop the victim’s SYN-ACK reply packets from reaching the attacker.



Step 3： check the result 





He is going to kill me.😈

Phonebook - Hack the box Write up -- Web LDAP injection

 0x00 Problem  0x01 Check the vulnerability When we see the login form on the website, it might be command injection, SQL injection, LDAP injection.  We can see that this need us to login with workstation username, it might be LDAP injection. 0x02 LDAP injection payload Here is the basic LDAP injection payload. We can check the vulnerability. user=*)(& password=*)(& --> (&(user=*)(&)(password=*)(&))  After we type it, we found the response shows successful, and return a page has search box. Then we type a character in the search box, and it returns some user phonebook information. I tried 'flag', 'HTB', it doesn't find any results. Then we try to find user 'Reese', but the information doesn't look like flag.   0x03 Locate the flag  Then we change our payload to check if the password is the flag. user=Reese password=HTB*)(& --> (&(user=Reese)(password=HTB*)(&  It can also return to the search page which means it...

wafwaf -- Hack The Box -- Web SQL injection

Image
0x00 Problem 0x01 Check the Source Code We open the website and only see the source code on the website. As we can see, there is a WAF will filter some characters and words, that means the normal injection will not work. However, we can see, there is a json_decode() function will decode JSON data, that means the data can be accepted should be JSON format.  The example JSON format data is like: /u0074, /u0075. In addition, there is a "php://input",  accesses the read-only stream of the requested raw data, executing the data in the post request as PHP code. 0x02 Local Test We can launch an Apache server to test it. I copy the source code and make a little change to test this. This file is in /var/www/html. We will construct the data first. This time I use 'select' as an example. The word transfer to ASCII, then to hex, then replace the '\0x' as '\u00'. This can be test in the browser console. At the end, we can test it with curl . As we can see, the SQL...
