What is an LLM penetration test?
Penetration tests against systems from the area of "GenAI" (Generative Artificial Intelligence) are becoming increasingly important, as these systems - primarily LLM (Large Language Models) - are increasingly being integrated into applications. In an LLM pentest, the focus is primarily on protecting the model, its data, manipulability and the security of the agent. A good starting point for an LLM test is the LLM-OWASP Top 10.
In general, the LLM penetration test always takes the form of a black box approach. We are the user who interacts with the LLM. This is usually a chat or voice application. From here we try to manipulate the system, extract data and compromise the integrity of the model.
Should an LLM pentest be combined with a web pentest?
It clearly depends on the focus. Both are closely related, as classic security gaps such as SQL injections or command injections can negatively affect both data and the model in many different ways. Here you should sit down together and decide together what makes sense. Arrange a free consultation with the CEO.

Costs of an LLM penetration test?
As is always the case in the area of IT security: It depends. Simple systems can be tested with a small four-digit budget. However, as complexity increases, the cost factor often increases. When it comes to systems that are highly complex, perhaps even with various agents, various different models that interact with one another, the price can quickly reach five figures.
The easiest thing you can do is send us a request. The more you can tell us about your system, the better we can give you a better number or make you an offer.
What is special about the LLM area is that it is sometimes necessary to train your own models in order to test certain things. One example of this is TextFooler, which can be used to generate manipulative inputs that can be used to test the LLM. This is particularly effective if you use your own models to generate this content - but these often have to go through what is known as fine tuning.
We are happy to check the security and integrity of your LLM model.
What vulnerabilities can LLM systems have?
The "OWASP Top 10 for Large Language Model Applications" are the best source in the area of LLM pentesting to understand the dangers lurking in this type of application. The most common problems with LLM applications are prompt injections and adversarial inputs. Manipulating the model using your own training data is also problematic, as this can lead to legal problems. However, a lot depends on the context of the application.
The issue of data leaks is also a major problem. Here, the attacker tries to manipulate the model in such a way that it reveals private data that it may have seen during training. Many vulnerabilities of this kind can be discovered partially automatically using complex applications such as garak. DoS attacks are also common, where the attacker tries to use the model in such a way that the underlying infrastructure is overloaded and/or enormous costs are generated.
Another important topic is agent control. Very simple LLM applications are often just chatbots. However, if an AI application becomes complex and multi-level, you often see that the AI internally generates commands for an agent, which the agent then executes. Here, the attacker's goal is to execute his own code and ultimately even take over the agent and steal the entire model. It is also possible that outputs are forwarded to other systems or components and can cause problems there.

Further questions and answers on the topic
"LLM/GenAI penetration testing"
What specific risks are examined in an LLM/GenAI penetration test?
It depends very much on the app. The focus is on the OWASP LLM Top 10. If your app has a web frontend, classic web security vulnerabilities (XSS, SQLi, ...) quickly come into focus. In terms of LLM, the focus is on data manipulation, prompt injections and adversarial input attacks.
How long does an LLM/GenAI penetration test usually take?
We are usually finished within a week. But as always - it depends on the size of the entire application. The larger and more complex, the longer it takes. We have also seen tests that took several weeks to complete.
What does the documentation of an LLM/GenAI penetration test from DSecured include?
In the case of LLM pentests, the report includes a management summary, technical details and recommendations for action. In addition, a large part of the report contains examples of how the system can be manipulated.
How often should an LLM system be tested?
In contrast to classic applications that are tested, in the case of LLM it is often the case that the model is trained with the help of user data, sometimes on a weekly or even daily basis. Theoretically, you would have to repeat the entire LLM pentest for each new model generation.
How up-to-date is your testers' knowledge of the latest GenAI technologies?
In addition to hacking LLM technology, we also build systems based on LLM for customers and for our internal systems. We know them from all perspectives and can therefore also test them better.
