What Is The Domain Generation Algorithm
Dga by itself can t harm you.
What is the domain generation algorithm. All dgas are based off of a static and dynamic seed which ensures that the domains are constantly changing. Kraken was the first malware family to use a dga in 2008 that we could find. The domain generation algorithm of bazarloader is in a single function including seeding click to enlarge.
Domain generation algorithm dga what is it. A domain generation algorithm dga is a computer program that creates slightly different variations of a given domain name. What are domain generation algorithms dgas.
Attackers use dga so they can quickly switch the command and control also called c2 or c c servers that they. A domain generation algorithm is a program that is designed to generate domain names in a particular fashion. Domain generation algorithms dga is a methodology for malware to form a command and control c c c2 connection without being detected.
But it s a proven technique that enables modern malware to evade security products and counter measures. Part of this is due to how the algorithm is set up and how easy they are to update. Determine the first six letters of the second level domain at random.
Dga is a technique that fuels malware attacks. Domain generation algorithm dga. 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.
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. Read about the typical components of a dga and go in depth with 8 real world examples. The algorithm roughly consists of these three steps.
