Domain Name Generation Algorithm

Part of this is due to how the algorithm is set up and how easy they are to update.

Domain name generation algorithm. Domain generation algorithm dga is a technique employed by the malware authors to prevent takedowns or blacklisting attempts of the c c domains. Domain generation algorithm from the kraken malware threatexpert walking through the assembly code shows that the domain is generated from a seeded algorithm which generates a complete url with a. Domain generation algorithms are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers.

A domain generation algorithm is a program that is designed to generate domain names in a particular fashion. Dga is used to generate a large number of domain names for the c c server. The idea is that two machines using the same algorithm will contact the same domain at a given time so they will be able to exchange information or fetch instructions.

Uses an algorithm to periodically generate a large number of domain names to connect to domains can be used to contact the c c servers and are generated and contacted everyday which makes them difficult to eliminate 1. Attackers developed dgas so that malware can quickly generate a list of domains that it can use for the sites that give it instructions and receive information from the malware usually referred to as command and control or c2. The use of public key cryptograph.

Malware can generate any number of domain names and contact a few of them every day receiving updates and actions to be executed. Domain generation algorithms create a constantly moving target that cyber defenders struggle to successfully hit with a blocklist. Adversaries may make use of domain generation algorithms dgas to dynamically identify a destination domain for command and control traffic rather than relying on a list of static ip addresses or domains.

The large number of potential rendezvous points makes it difficult for law enforcement to effectively shut down botnets since infected computers will attempt to contact some of these domain names every day to receive updates or commands. A domain generation algorithm dga is a computer program that creates slightly different variations of a given domain name. Constant changing of the domain name for the c c server through the implementation of dga is known as domain fluxing.

This has the advantage of making it much harder for defenders block track or take over the command and control channel as.
