As these dgas become more sophisticated and increasingly difficult to detect zvelo s cyber threat intelligence team is recommending heightened awareness as they anticipate this to be a prominent.
Domain generation algorithm dga. Dga is a technique that fuels malware attacks. I ve also written a c program that uses the same dga algorithm for generating the domain names which can be seen below. The article shows that the dga is part of bazar loader which will try to download bazar backdoor.
Domain generation algorithm dga what is it. Kraken was the first malware family to use a dga in 2008 that we could find. These domains are often used as rendezvous points for the servers that malware has command and control over.
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. But it s a proven technique that enables modern malware to evade security products and counter measures. Later that year conficker made dga a lot more famous.
Attackers use dga so they can quickly switch the command and control also called c2 or c c servers that they. Dga by itself can t harm you. A basic implementation uses 3 specific parts.
Over the last decade domain generation algorithms dgas have become a popular tool for threat actors to deliver malware as it has become a difficult technique for defenders to counter attacks. Domain generation algorithms dgas are frequently used to generate large numbers of domains for use by botnets. There are many algorithms that are used to generate domains but many of these algorithms are simplistic and are very easy to detect using classical machine learning techniques.
They only show the seeding part of the domain generation algorithm however the listing of generated bazar domains matches the algorithm in this blog post apart from the first two domains alztwfdicu bazar and ocgjqlaspr bazar which are hardcoded. One of the most important innovations in malware in the past decade is what s called a domain generation algorithm dga. The program defines a function with the same name generate domain which accepts current year month which influence the domain generation algorithm the function reserves some space on the stack for the domain variable which is 25 bytes long so it can hold the actual.
