Attacks

Website attacks are malicious actions impacting web resources on the Internet.

UDP flood is a network-based DoS attack carried out by sending large amounts of UDP packets to a remote host’s ports.

A DDoS attack carried out using fragmented packets with an offset, based on exploiting a TCP/IP stack vulnerability.

When the term is used in relation to popular protocols, it means a DDoS attack that exploits vulnerabilities previously unknown to security experts.

A piece of software code or module used for attacking vulnerable nodes in order to gain command and control over them, carry out a destructive action, or cause a denial of service.

A way to implement a DoS attack providing a manifold increase in impact on a victim server: a small number of bots initiate sending a huge amount of forged packets or requests, which severely slow down or paralyze the attacked server that tries to process them.

Bot is a software robot designed for executing certain actions determined by algorithms or rules. Botnet stands for a "robot network".

A Smurf attack is a type of DDoS attack that exploits the ICMP protocol and causes a stream of packets to the victim. At startup, large packages are created when using a method called "spoofing". The intended result is to slow down the target system to such an extent that it becomes inoperable and vulnerable.

DoS is an attack against a system aiming to cause it to stop providing a service.

A DoS attack, a variant of UDP flood implemented by sending large amounts of forged VoIP packets from a wide range of IP addresses to a VoIP server, usually used by a call center. As a result, the server wastes too much of its resources trying to handle the bogus requests. Due to some aspects of UDP protocol, a VoIP flood attack can be very hard to detect.
