Vulcan DoS Vs Akamai

Posted by KP-3မိသားစု |

In the past I had to do several DoS security audits, with múltiples types of tests and intensities. Sometimes several DDoS protections were present like Akamai for static content, and Arbor for absorb part of the bandwith.

One consideration for the DoS/DDoS tools is that probably it will loss the control of the attacker host, and the tool at least has to be able to stop automatically with a timeout, but can also implement remote response checks.

In order to size the minimum mbps needed to flood a service or to retard the response in a significant amount of time, the attacker hosts need a bandwith limiter, that increments in a logarithmic way up to a limit agreed with the customer/isp/cpd.

There are DoS tools that doesn't have this timeouts, and bandwith limit based on mbps, for that reason I have to implement a LD_PRELOAD based solution: bwcontrol

Although there are several good tools for stressing web servers and web aplications like apache ab, or other common tools used for pen-testing, but I also wrote a fast web flooder in c++ named wflood.

As expected the most effective for taking down the web server are the slow-loris, slow-read and derivatives, few host were needed to DoS an online banking.

Remote attacks to database and highly dynamic web content were discarded, that could be impacted for sure.

I did another tool in c++ for crafting massive tcp/udp/ip malformed packets, that impacted sometimes on load balancers and firewalls, it was vulcan, it freezed even the firewall client software.

The funny thing was that the common attacks against Akamai hosts, where ineffective, and so does the slow-loris family of attacks, because are common, and the Akamai nginx webservers are well tunned. But when tried vulcan, few intensity was enough to crash Akamai hosts.

Another attack vector for static sites was trying to locate the IP of the customer instead of Akamai, if the customer doesn't use the Akamai Shadow service, it's possible to perform a HTTP Host header scan, and direct the attack to that host bypassing Akamai.

And what about Arbor protection? is good for reducing the flood but there are other kind of attacks, and this protection use to be disabled by default and in local holidays can be a mess.

BruteSpray: A Brute-forcer From Nmap Output And Automatically Attempts Default Creds On Found Services

Posted by KP-3မိသားစု |

About BruteSpray: BruteSpray takes nmap GNMAP/XML output or newline seperated JSONS and automatically brute-forces services with default credentials using Medusa. BruteSpray can even find non-standard ports by using the -sV inside Nmap.

BruteSpay's Installation

With Debian users, the only thing you need to do is this command:
sudo apt install brutespray

For Arch Linux user, you must install Medusa first: sudo pacman -S medusa

And then, enter these commands to install BruteSpray:

Supported Services: ssh, ftp, telnet, vnc, mssql, mysql, postgresql, rsh, imap, nntpp, canywhere, pop3, rexec, rlogin, smbnt, smtp, svn, vmauthdv, snmp.

How to use BruteSpray?

First do an Nmap scan with -oG nmap.gnmap or -oX nmap.xml.
Command: python3 brutespray.py -h
Command: python3 brutespray.py --file nmap.gnmap
Command: python3 brutesrpay.py --file nmap.xml
Command: python3 brutespray.py --file nmap.xml -i

Examples

Using Custom Wordlists:

python3 brutespray.py --file nmap.gnmap -U /usr/share/wordlist/user.txt -P /usr/share/wordlist/pass.txt --threads 5 --hosts 5

Brute-Forcing Specific Services:
python3 brutespray.py --file nmap.gnmap --service ftp,ssh,telnet --threads 5 --hosts 5

Specific Credentials:
python3 brutespray.py --file nmap.gnmap -u admin -p password --threads 5 --hosts 5

Continue After Success:
python3 brutespray.py --file nmap.gnmap --threads 5 --hosts 5 -c

Use Nmap XML Output:
python3 brutespray.py --file nmap.xml --threads 5 --hosts 5

Use JSON Output:
python3 brutespray.py --file out.json --threads 5 --hosts 5

Interactive Mode: python3 brutespray.py --file nmap.xml -i

Data Specs

{"host":"127.0.0.1","port":"3306","service":"mysql"} 
{"host":"127.0.0.10","port":"3306","service":"mysql"}

Fragroute

Posted by KP-3မိသားစု |

"fragroute intercepts, modifies, and rewrites egress traffic destined for a specified host, implementing most of the attacks described in the Secure Networks "Insertion, Evasion, and Denial of Service: Eluding Network Intrusion Detection" paper of January 1998. It features a simple ruleset language to delay, duplicate, drop, fragment, overlap, print, reorder, segment, source-route, or otherwise monkey with all outbound packets destined for a target host, with minimal support for randomized or probabilistic behaviour. This tool was written in good faith to aid in the testing of network intrusion detection systems, firewalls, and basic TCP/IP stack behaviour." read more...
