Domain Generation Algorithm Example

A malware that uses a domain generation algorithm can generate thousands of domain names at once.

Domain generation algorithm example. Dissecting domain generation algorithms. An analysis to discover the dga. Therefore threat actors would need to register a portion of these dga generated domain names.

Following team9 s development cycles 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. Domain generation algorithm monitoring. Dga is a technique that fuels malware.

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. Conficker c for example can generate up to 50 000 domain names per day and only 500 of these are queried. As critical workloads with sensitive data migrate to the cloud we can expect to encounter various advanced persistent threats apt targeting that environment.

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. The domain generation algorithm has remained a main source of communication for malware in the past 10 years.

Domain generation algorithms dgas are frequently used to generate large numbers of domains for use by botnets. Introduction 2020 is predicted to be an exciting year with more organizations adopting kubernetes than ever before. Dgas are designed to generate quick random seeds such as dictionary words dword values random digits gibberish strings hcbhjbdjbjhsb ru as domains which can be used to provide instructions for malware to exfiltrate data provide.

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. Due to the fact that dga domains are generated randomly they tend to be. Cybereason published an excellent article a bazar of tricks.
