Domain Generation Algorithm Explained

Domain generating algorithms a domain generating algorithm dga is a program or subroutine that provides malware with new domains on demand or on the fly.

Domain generation algorithm explained. 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 seed is a piece of information accessible to both the bot herder and the infected host now acting as a bot. For a dga to be functional idempotence on domain generation is required.

A domain generating algorithm dga is a program or subroutine that provides malware with new domains on demand or on the fly. Part of this is due to how the algorithm is set up and how easy they are to update. In order to form a possible domain name.

Domain generation algorithms dga 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 the large number of potential rendezvous points makes it difficult for law enforcement to effectively shut down botnets since infected computers will attempt to. All dgas are based off of a static and dynamic seed which ensures that the domains are constantly changing. A basic implementation uses 3 specific parts.

Kraken was the first malware family to use a dga in 2008 that we could find. Domain generation algorithm dga. A subset of these domains.

Both malware instances spread on various devices and the hacker controlled software should be able to run the algorithm and produce the same values at a given time. Domain fluxing is a technique used by botnets and command and control c2 servers to create many domains using a domain generation algorithm dga 7 8. Later that year conficker made dga a lot more famous.

Domain generation algorithms create a constantly moving target that cyber defenders struggle to successfully hit with a blocklist.
