Take down website using Slowloris DoS attack



A DoS attack is a type of attack where an attacker can suspend services of a host or a website by sending a large number of traffic and making request constantly from two or more computer or by sending large number of packet (for which you can find tutorial here )which make small servers overload and server goes crash and result "Destination unreachable"

Here i am going to DOS using Perl base program name Slowloris developed by Robert "RSnake" Hansen. Slowloris is very effective program which allows a single machine to take down another machine's web server with minimal bandwidth and side effects on unrelated services and ports. It keep connection open of the target and keep sending request and after some time some become unresponsive to other request which result in server down. It is very easy to use this program for which i am going to give step by step tutorial below

STEP 1 As i said it's Perl base program, mostly i use this program on some Linux distro but i will use Windows this time so that lots of user can use this. So to run this program you have to install Per on your computer so first download Perl from : HERE

STEP 2 : In this step you have to copy some text from the Slowloris and paste it to your notepad but for saving time i have already done these steps for you so you have to download this slowloris program from here : DOWNLOAD

STEP 3 : Save it to your c drive for example c:\"slowloris"


STEP 4 : Now go to command and type cd:\


STEP 5 Now type slow.pl to run Slowloris.pl to check you have done above steps correctly or not.If you have done above steps correctly then you will see Slowloris



STEP 4 OK now you have to choose your target as i am going to attack on a vulnerable website, here you don't need to ping the website to get the IP address

STEP 5 OK now we came to the main point in the command type "slow.pl -dns www.yourtarget.com -port 80 -timeout 500 -num 500 -tcpto 5 -httpready "


Now Slowloris will start sending packets to your target



And now after waiting some time the site has been taken down as you can see i am pinging to google to prove that my internet is working 



If you want to make it more powerful then run multiple Slowloris attack as shown below
but watch out for CPU heat and process

So guys i have shown you How to DOS a website now follow above steps and Happy Hacking

For example if we want to find paste for specific keyword like "password" we can get all the paste containing that keyword. Preparing the Attack Usually some sites don't allow web crawling and by doing so you may get banned from accessing that site, which will also make this method vain.  So before doing this i recommend you to use THIS tool to anonymize all your traffic so that if we get banned we can switch our IP address immediately.  Start the Attack STEP 1 Clone into this URL by typing https://github.com/kahunalu/pwnbin.git STEP 2 Now type python pwnbin.py -k pass -n 10 -m 10 here "-k" is the keyword you want to search for "-n" is the number of paste you want to crawl and "-m" number of keywords matches you want.  As we can see above we have found a match and it's now saved to log.txt file so it's time to see the dump co

Fileless malware Analysis with Cuckoo sandbox

Image
What is cuckoo Sandbox Cuckoo is a dynamic malware analysis sandbox which is open source and completely free. We can submit any malicious binary file and cuckoo will provide a detailed report of the malicious file, including the behaviour of that file during execution.   What is Fileless Malware A fileless malware is a favorite technique for malware authors, what this type of malware does, it doesn’t write anything on the disk to bypass mostly string base detection. The malware executes an obfuscated command usually PowerShell and during run time antivirus could not detect the strings which are being executed and after injecting it in memory the command get deobfuscated. Cuckoo Interface and sample analysis To run cuckoo just type cuckoo from your terminal, this will start cuckoo service. Now to get the web interface type cuckoo run webserver this will start the cuckoo web interface on its defined URL and port address as shown below.

Every pentester has it's own tool and technique for web app security auditing, Some time it depend on the type of website  we are pentesting. We are gonna see some common tool and technique that can help us to audit our web application security. Detecting web application firewall and other services You can start with by detecting is there any web application firewall in use? Later we can see if there's any way to bypass it.  Recommend tool :  fofa.so It is a cyberspace search engine launched by White Hat. It can help researchers or enterprises quickly match network assets by performing cyberspace mapping, for example, analyzing the scope of vulnerability.  shodan.io It is most poplar search engine among pentester for finding various online vulnerable IoT devices, online open ports f rom various web servers. wafw00f   This tool allow you to detect and identify what Web Application is in use that is protecting the website.  Bypassing Cloudfl
