LOIC had both TCP and UDP DDoS attacks in addition to HTTP attacks were as HOIC is strictly an HTTP DoS tool. Epistemologia Para Principiantes Pdf. Dec 13, 2014 Low Orbit Ion Cannon.

One of the reasons hacktivism has gained greater visibility recently is that it's now very easy to obtain and use attack tools, especially those that perform denial-of-service (DoS) attacks. The goal of hacktivists is usually to protest or promote a particular political issue, but these days anyone can become a target of theses types of attacks, even if it's 'just for the lulz'. I recently had the opportunity to witness a hacktivist DDoS attack (announced by Anonymous in advance) and here, I'll share the tools they used and some tips on how to defend against these types of incidents. The attack tools A denial of service attack is basically an attempt to negate access to a resource (usually a web server) to its users. A distributed denial of service attack involves multiple machines performing the attack in concert. There are many tools that can be used to launch DoS attacks, but let's just take a look of the most popular right now: • The Low Orbit Ion Cannon (LOIC) is perhaps the most well-known tool used by Anonymous and other hacktivists for performing DDoS attacks.

The LOIC might have legitimate uses as a stress-testing tool but it became more widely used as a DoS tool. It's popularity led to the creation of a JavaScript version, enabling attacks from a web browser and allowing attackers to easily get their followers (or unwary visitors) to join the attack. • HPing is a command line utility similar to the ping command, but has many more advanced capabilities.

It can be used to create huge amounts of TCP traffic and perhaps the most important characteristic for attackers is the ability to mask the source of an attack via spoofing. • Slowloris on the other hand, performs DoS attacks by making slow, partial HTTP requests, keeping IP sockets open on the server and eventually consuming all of its available network ports. This tool requires Perl and runs better on Linux, so it might not be a tool for regular users. On their own, each of these tools can be an effective way of taking down web servers. An attack using a combination of these tools however, has the potential of being very powerful and difficult to stop. As many would-be attackers have learned, a tool like the LOIC does nothing to protect the identity of the source of the attack.

Anonymous promotes the use of VPN services as a way to cover the true source of the attacks. This might no longer be the best way to cover their tracks; the arrest of an alleged LulzSec member shows that VPN service providers (like the one he used, HideMyAss.com) can and will. The countermeasures Organizations have to be ready to face possible DoS attacks.

Here are some basic strategies that can be used to defend against an attack: • Configure your routers and firewalls to stop invalid IP addresses and filter out protocols that are not needed. Some firewalls and routers include features to prevent TCP/UDP floods. Also, make sure that logging is enabled in all your devices and that you can reliably examine them to identify attacks and if needed, turn them over to law enforcement authorities. • An intrusion-detection/prevention system (IDS/IPS) can detect the misuse of valid protocols as attack vectors. Game Mode Samp Roleplay Indonesia more.

Depending on the products and your network configuration, it's possible to automatically block the attack traffic. • Get help from your provider. This way, attack traffic can be blocked closer to its source before it can clog your organization's bandwidth. • You should have an incident response plan in place and be ready to activate it.

If an attack comes, everyone should know how to respond and who to contact both inside and outside the organization (law enforcement for instance). • Ensure that you have means of communicating with your users and/or customers. Be as honest and forthcoming as you can about the incident. Facebook Mobile Samsung Omnia I900. You must also be aware of some issues that can derail your defense strategies: • Make sure you've taken the time to properly tune your IDS/IPS and that its detection signatures are up to date.
