4 DDoS Attacks That Every Website Owner Should Be on the Lookout For

4 DDoS Attacks That Every Website Owner Should Be on the Lookout For

Hackers use a multitude of methods to leave their mark. With constant advances being made in the field of cyber security, cybercriminals have proven themselves to be incredibly adaptive. This doesn’t bode well for website owners who don’t keep up with the latest threats or devote sufficient resources to keeping their sites safe. In the absence of effective security solutions, hackers can strike without warning and cause long-lasting damage to both your website and its reputation. Never is this more apparent than in the case of distributed denial of service (DDoS) attacks. These attacks overload target servers with malicious requests, ultimately causing them to go offline for indeterminate periods. If your website is dedicated to promoting a business or used to generate income, a DDoS attack can be extremely hard to weather. In the interest of long-term website security, you’ll need to invest in comprehensive solutions and keep an eye out for the following DDoS threats.

HTTP Floods

Due to the use of legitimate IPs, HTTP floods can be particularly difficult to detect. This type of attack occurs when a target server is flooded with a massive number of bot requests. Because the bots used to carry out HTTP floods have real IPs as opposed to spoofed ones, most servers’ defense mechanisms are unable to detect anything malicious about their requests. In some instances, a single bot is used to send an unmanageable number of HTTP, POST or GET requests, thereby causing the server to exhaust its resources and go offline. If hackers are feeling aggressive, they may instruct numerous bots to flood the server with requests, which can cause substantial damage. Website owners who are determined to keep dangerous bots away from their sites can do so with the aid of cutting-edge security software. You can read up on cloud-based solutions by consulting a SiteLock review.  

CharGEN Floods

CharGEN is an old service protocol that can be exploited in a variety of ways. As such, there’s little wonder as to why it’s a favorite tool of dedicated hackers. A CharGEN flood involves sending small packets containing a spoofed IP of the target server to a network of computers running CharGEN. The spoofed requests sent to these computers are then used as a vehicle for sending UDP floods as responses from the computers to the target server. Furthermore, computers aren’t the only devices capable of carrying out CharGEN floods. Even printers and copiers with the CharGEN protocol enabled can be used to perpetrate a flood.

Fragmented HTTP Floods

A variation of the traditional HTTP flood, fragmented HTTP floods can be hard-hitting and very tricky to pinpoint. Like standard HTTP floods, fragmented floods rely on bots with legitimate IP addresses to establish a connection with the target server. Once a connection has been made, bots will split HTTP packets into miniscule fragments and send them to the target server as slowly as possible. This ensures that hackers are able to maintain an active connection for a long time without setting off any security mechanisms. When this action is repeated by enough bots, the server’s resources are depleted, causing it to shut down.

SYN Floods

SYN floods are particularly complex and sneaky. These DDoS attacks seek to exploit the communication process between clients, hosts and servers. When a new SYN packet is generated, a new client session is initiated.  The server is in charge of assigning and checking each session until the client decides to end it. In executing this type of attack, hackers send an excessive number of SYN packets from spoofed IP addresses to the target server. This process is repeated until the server gives out and is forced to go offline.  

Few things are more detrimental to a site’s success than a concentrated DDoS attack. In many cases, sites that are hit by distributed denial of service attacks remain offline for weeks. For people who depend on their sites for income, this can lead to a host of financial problems. It can even result in financial ruination for online stores and ecommerce sites. With this in mind, staving off DDoS strikes should factor prominently into the security goals of every website owner.
