What Is The Domain Generation Algorithm
Domain generation algorithms dga is a methodology for malware to form a command and control c c c2 connection without being detected.
What is the domain generation algorithm. A domain generating algorithm dga is a program or subroutine that provides malware with new domains on demand or on the fly. Read about the typical components of a dga and go in depth with 8 real world examples. 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.
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 create a constantly moving target that cyber defenders struggle to successfully hit with a blocklist. A domain generation algorithm is a program that is designed to generate domain names in a particular fashion.
A domain generation algorithm dga is a computer program that creates slightly different variations of a given domain name. In contrast dgas use algorithms to periodically generate a large number of domain names which function as rendezvous points for malware command and control servers mitre att ck t1568 002. All dgas are based off of a static and dynamic seed which ensures that the domains are constantly changing.
A dga is an algorithm able to generate a fqdn for allowing communication between a virus or malware and its command and control master. What is domain generation algorithms dga. What are domain generation algorithms dgas.
Traditionally malware used to have hard coded domain names or ip addresses to connect directly with the command and control c c or c2 server. Part of this is due to how the algorithm is set up and how easy they are to update.
