To catch up on the latest amplification methods I decided to write this post to give a short review for them. RIP amplification method is a shortcutNew amplification methods : RIP AND PORTMAP for the Routing Information Protocol which is a UDP service working on port 520. Its amplification rate is pretty decent at about […]

A DDoS Attack : TCP SYN ACK Flood
Continuing on with explanations of attack vectors, we will be discussing a TCP SYN ACK flood. A TCP packet with the SYN ACK flag enabled is used as part of the three step process involved with establishing a TCP connection. 1. SYN packet. During this stage, a client (such as a desktop computer, laptop, or […]
A DDoS Attack Explained: TCP SYN Flood
A SYN flood is perhaps one of the most common forms of DDoS attack seen today. SYN floods rely on exploiting how a basic TCP connection is formed, essentially. TCP connections take place in three stages (commonly known as the three-way handshake): 1. SYN. During this stage, a client (such as a desktop computer, laptop, […]
A DDoS Attack Explained: HTTP Flood
HTTP floods are one of the most devastating types of DDoS attacks currently available to an attacker. It is an attack at the application layer (Layer 7 of the OSI model), meant to exhaust a system’s application resources. It is very easy to execute, doesn’t require a massive botnet or any sort of tricks to […]
Free Cloud Services and How They Are Used for DDoS
Free cloud services have become popular in recent years. These services provide developers a platform to test software, and collaborate with others easily. While this sounds amazing, in reality these platforms can be a goldmine for attackers if not properly secured. Many of these services require only an email for verification. Setting up fake emails […]
A History Lesson: Apple’s Patented Method for Amplifying DDoS
In late-1999, Apple was granted US Patent No 5,931,961 for Discovery of acceptable packet size using ICMP echo. A form of this mechanism was implemented in Mac OS 9 and was soon misused as a means of amplifying DDoS attacks . This patent is widely-cited by inventors at other Internet giants, but the mistake in its method […]
Fear and Loathing in TCP: Reexamining Hackers
In 1995, Angelina Jolie portrayed a computer hacker that went by the alias Acid Burn. At the time, I had limited access to movies, as well as most other forms of entertainment and culture. I was not aware of seminal hacker movies such as Wargames or Sneakers (if you have not yet seen these, drop […]
Tunneling Traffic Through DNS to Bypass Firewalls
Monitoring and analyzing your network traffic is more of an art form than a science: every network is unique. The differences appear in the services we run, the types of traffic we generate, as well as our network design and layout. In order to properly analyze traffic dumps, we must first know what kind of […]
WordPress Real IP detector
This plugin allow WordPress to detect visitors Real IP Address when WordPress is behind of Reverse Proxy, Load Balancer. It will start working as soon as you activate it. It is also compatible: Cloudflare.com geniusguard.com central-hosting.com incapsula.com sucuri.net barracuda.com f5.com And Other… Real IP Detector
Everything About TCP ACK Flood
We’re continuing along with our explanations of types of DDoS attacks today, with emphasis on the TCP ACK flood. Much like we discussed on Tuesday, this form of attack is a part of making a TCP connection. When a client establishes a TCP connection to a server, the connection goes through a three step process. […]
Zombie Routers That Just Refuse To Die
Scans of the internet reveal that over fifty three thousand IPs respond with dilapidated devices operating the ancient RIPv1 protocol. This deprecated protocol was implemented before much care was given to the proliferation of spoofed UDP attacks. It hails from a time before classless internet address routing, and long before the surging threat of ddos […]
CloudFlare can’t stop DDoS attacks ?
Most of the time I see this happen because someone mistakenly thinks we are a DDoS service & mentions it on board. When it comes to an attack, unfortunately, people rush to find a quick fix to the problem. There are some things that we do that can help with smaller attacks & there are […]
OVH IP Configure firewall Add Rule for Anti DDOS
Mitigation is a term employed to design the means and measures in place that reduce the negative effects of a DDoS attack. You need OVH IP Configure firewall Add Rule for Anti DDOS. Mitigation consists of filtering illegitmate traffic and hoovering it up with the VAC, while letting legitmate packets pass. The VAC consists of […]

About spoofing
When the DDoS topic is brought up, it’s almost always that the spoofing subject is brought up as well. In this post I will try to answer a few questions about Spoofing and DDoS attacks that are performed via spoofing. First of all, what is spoofing? Spoofing is the act of modifying the IP header […]
Dominate Method Attack
Dominate Method Attack is a New method of DDoS Attack on Layer4 of Network. the method is able to drop servers from ddos protected networks such as OVH, Voxility by bypassing their firewall and sending the attack straight to the server itself, therefore causing it crash completely. As for the moment, as a server owner […]
Apache Killer
“Apache Killer” is a severe vulnerability (discovered in August 2011) affecting the widely used Apache web server. Despite the fact that the vulnerability had been previously described in January 2007 by Google security researcher Michal Zalewski, it was only patched in Apache version 2.2.20 (released a week after knowledge of the vulnerability was public in […]
TCP SYN ACK Attack
A TCP SYN ACK Attack flood is an attack method that involves sending a target server spoofed SYN-ACK packet at a high rate. Because a server requires significant processing power to understand why it is receiving such packets out-of-order (not in accordance with the normal SYN, SYN-ACK, ACK TCP three-way handshake mechanism), it can become […]
Hacking vs DDoS
Hacking has really taken on bad meaning over the past two decades. What began as software augmentation on a rapid development cycle has been popularized by movies like “Hackers” and “Swordfish” as underground and often sociopathic perpetration of evil. Interest has again been stirred with the holiday attacks against video game services and the release […]
