20 years of DDoS attacks

In July 1999, a set of computers infected with the Trin00 malware attacked and took down the network of the University of Minnesota. The episode marked the first recorded case of a distributed-denial-of-service (DDoS) attack. 20 years later, DDoS has evolved into one of the most serious security threats from the arsenal of both cybercrime gangs and nation-state actors. What is DDoS? or Denial of service attack define As the name implies, the goal of DDoS attacks is to prevent the target website from providing service to its users by flooding its servers with bogus traffic and starving its resources. Before engaging in DDoS, attackers typically assemble a “botnet”. Botnets are sets of computers compromised with a malware that enables the attacker, the “bot master,” to send them remote commands. After assembling their army of zombie devices, bot masters can launch DDoS attacks by commanding their botnet to simultaneously send fake requests to the target. With a strong enough

How do attackers launch DDoS?

First, hackers need to get the DDoSTool onto your system. To that end, cybercriminals rely on a whole bag of tricks to enslave your PC, Mac, Android, iPhone, or company endpoint into their botnet. how does a ddos attack work ? Here are some common examples: An email attachment. In a moment of bad judgment, you click on either an attachment or link to a website that the attacker controls, and which hosts the malware it sends you. Your social network or messaging app. Like emails, they can include links that attackers want you to click on, again, to trigger download of a DDoSTool. Drive-by downloads or click scams. If you surf on a legitimate—albeit infected—website, you don’t even have to click on anything to have the malvertising download botnet malware. Or you fall prey to a pop-up that displays an “urgent” message that prompts you to download some allegedly necessary antivirus security (it’s malware). After the DDoSTool infection takes root, your computer remains seemingl
