What are the different kinds of DDoS Attacks? These connected devices make easy targets for hackers as they typically lack the security protections of personal computers, are rarely patched, and are frequently left with default credentials for login. Botnets typically include personal devices like PCs and mobile phones that have been infected with malware but are increasingly comprised of unsecured connected IoT devices, such as smart TVs and appliances webcams, and even industrial devices. What is a DDoS Botnet?Ī botnet is a network of bots made up of hijacked devices that the attacker controls remotely to carry out DDoS attacks. Following the attack, Dyn lost approximately 8% of its customer base–about 14,000 customers. For example, in 2016 Dyn, a major domain name service (DNS) provider, was hit with a one terabit per second DDoS attack that knocked its services offline, taking down the websites of multiple high-profile customers such as HBO, Twitter, Reddit, PayPal, Netflix, GitHub, and Airbnb, along with thousands of other customers. For certain targets, such as web services, the effects can be even more devastating. The intended and most noticeable effect of a successful DDoS attack is that it takes the targeted service offline, but depending on the severity of the attack, and the nature of the service targeted, the attacks can have massive downstream effects as well.ĭDoS attacks can last minutes or take days to resolve, and during that downtime customers and employees alike will be unable to access company resources, resulting in both lost revenue as customers take their business elsewhere, and wasted resources as workers are unable to fulfill their tasks. These attacks work faster, carry a heavier toll, and are much harder to mitigate, due to the volume of devices involved. Unlike DoS attacks, DDoS attacks are carried out from many disparate connected devices, often numbering in the thousands, with different IPs and signatures. The user may carry this task out manually or may leverage a DoS tool, such as Low Orbit Ion Cannon (LOIC) which helps users flood target servers with TCP, UDP, or HTTP packets in order to disrupt service.īecause DoS attacks rely on a single internet connection, they are typically carried out at a much slower pace than DDoS attacks, are much easier to trace, and can easily be mitigated through IP blocking or filtering. In a traditional DoS attack, the attacker leverages a single internet connection to send the target large volumes of data in an attempt to use up server resources. The differences between traditional denial of service (DoS) attacks and distributed denial of service (DDoS) lie in both the scale and execution of the attack. What’s the difference between Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks? Download our Free State of Fake Traffic 2023 report to learn more. They’re also commonly leveraged by sophisticated attackers looking to create a smokescreen to engage and distract the target’s IT team while they infiltrate the security perimeter.ġ1.3% of inbound traffic is fake or fraudulent. The sole purpose of a DDoS attack is to take the target offline.ĭDoS attacks are used for a wide variety of reasons: they’re popular with hacktivists who use them as political statements, bored vandals, and even with malicious users, who may use a DDoS to carry out a personal vendetta. These attacks are almost always carried out by botnets, large networks of connected devices (which could be user devices or simple IoT devices) infected and controlled by bots.Įssentially, a DDoS attack is a targeted, intentional traffic jam that keeps real users from getting to your business.ĭDoS differ from most cyberattacks in that they are not, in and of themselves, an attempt to breach a network or website, and cannot be leveraged to steal data. What are the different kinds of DDoS Attacks?Ī distributed denial of service (DDoS) attack is an advanced form of denial of service (DoS) attack that attempts to disable a target website or service by flooding it with a massive volume of fake traffic, thus consuming the target’s upstream bandwidth or overwhelming supporting network infrastructure and taking it offline.What’s the difference between Denial of Service (DoS) and Distributed Denial of Service (DDoS) Attacks?.
