The Ping of Death is a type of cyberattack that exploits vulnerabilities in a system’s ability to handle oversized or malformed packets, causing crashes, freezes, or reboots. Despite being considered an old-school method, this attack still poses a threat today when modern devices or poorly configured networks fail to implement proper protections.

What Is the Ping of Death?

At its core, the Ping of Death is a Denial of Service (DoS) attack. It involves sending malicious ping packets, specifically Internet Control Message Protocol (ICMP) packets that exceed the maximum byte size allowed by the protocol. Typically, a standard ping packet should be no larger than 65,535 bytes, including headers. However, the Ping of Death breaks this limit by sending fragmented packets that reassemble into oversized data when processed by the target system. This overwhelms the memory buffer, causing instability or total system failure.

In today’s digital landscape, where businesses heavily rely on the internet for communication, transactions, and operations, the security of online activities has become paramount. While organizations implement various cybersecurity measures to safeguard their sensitive data, one lesser-known yet highly potent threat remains – DNS spoofing. This article sheds light on the potentially catastrophic consequences of DNS spoofing for businesses and highlights the urgency of addressing this hidden peril.

What is DNS spoofing?

DNS, or Domain Name System, serves as the internet’s phonebook, translating human-readable domain names into IP addresses that computers use to locate and connect with each other. DNS spoofing involves manipulating this translation process, leading users to fraudulent or malicious websites that closely resemble legitimate ones. Attackers accomplish this by corrupting the DNS cache, rerouting traffic to malicious servers, and subsequently gaining unauthorized access to sensitive information.

DNS attack types are getting more and more every year. Just as the Internet expands every day, unfortunately, online crime grows too. Motivations can be different. Extortion is on the top rank, but also boredom, people trying to prove their computing skills, the so-called hacktivism, or to take down a competitor.

In any case, different DNS attack types take advantage of the multiple Domain Name System (DNS) vulnerabilities. They have different ways to operate but all of them are dangerous for your business. Let’s get familiar with the most popular DNS attack types.

Meaning of DDoS attack

A DDoS attack, also known as a Distributed Denial of Service attack, is a major cyber threat that cybercriminals frequently launch against their targets. They overwhelm the victim’s server, system, or network due to this cyber-attack. A botnet of devices, commonly known as a DDoS attack, sends enormous amounts of fake traffic to the target as part of the DDoS attack. The victim is eventually saturated, rendering them unable to function.
