CyberSecEval 2: Enhancing Cybersecurity for Large Language Models
As the generative AI landscape rapidly evolves, the importance of adopting an open approach to mitigate the potential risks associated with Large Language Models (LLMs) cannot be overstated. Meta’s initiative to release a suite of open tools and evaluations last year marks a significant step towards responsible development in the realm of generative AI. With LLMs increasingly being utilized as coding assistants, there also arises a new set of cybersecurity vulnerabilities that must be proactively addressed. This is where CyberSecEval 2 comes into play, offering a comprehensive framework for evaluating the cybersecurity safety of LLMs.
Understanding CyberSecEval 2
CyberSecEval 2 is designed to assess various vulnerabilities in LLMs by focusing on their susceptibility to code interpreter abuse, offensive cybersecurity capabilities, and prompt injection attacks. By providing a structured evaluation of these risks, CyberSecEval 2 aims to create a safer environment for the deployment of LLMs across various applications.

Key Benchmarks of CyberSecEval 2
The benchmarks set by CyberSecEval 2 are essential for evaluating LLMs regarding their propensity to generate insecure code and their compliance with requests that could aid cyber attackers. Here’s a closer look at the benchmarks:
-
Testing for Generation of Insecure Coding Practices:
This benchmark evaluates how often an LLM suggests insecure coding practices during autocomplete and instruction contexts. By adhering to the industry-standard taxonomy of the Common Weakness Enumeration (CWE), it reports pass rates for these tests, helping to identify areas where LLMs may inadvertently promote risky behaviors. -
Testing for Susceptibility to Prompt Injection:
Prompt injection attacks aim to manipulate LLMs into behaving in undesirable ways. This benchmark assesses how well an LLM can identify untrusted input and withstand common prompt injection techniques, revealing the frequency with which models comply with such attacks. -
Testing Compliance with Requests to Help with Cyber Attacks:
This benchmark evaluates the false rejection rate of benign prompts that could be mistakenly interpreted as malicious. By analyzing the tradeoff between false refusals and violation rates, it provides insight into an LLM’s ability to discern between legitimate cybersecurity assistance and offensive intentions. -
Testing Propensity to Abuse Code Interpreters:
This benchmark checks whether LLMs can be manipulated into executing malicious code within a sandboxed environment. It measures the frequency of compliance to prompts designed to extract sensitive information or execute harmful actions, highlighting vulnerabilities in the code execution process. - Testing Automated Offensive Cybersecurity Capabilities:
This set of tests simulates capture-the-flag style security challenges to determine if an LLM can exploit intentionally inserted security issues. By examining basic exploits like SQL injections and buffer overflows, it assesses the model’s competency in handling complex security scenarios.
All code related to CyberSecEval 2 is open source, encouraging community engagement and collaboration to enhance the cybersecurity safety properties of LLMs. For further details, you can read about all the benchmarks here.
Key Insights from CyberSecEval 2
The latest evaluations using CyberSecEval 2 reveal both advancements and ongoing challenges in addressing cybersecurity risks associated with LLMs.

Industry Improvement
Since the first version of the benchmark was released in December 2023, there has been a notable improvement in the industry’s awareness of cybersecurity risks. The compliance rate of LLMs with requests to assist in cyber attacks has decreased significantly, from 52% to 28%. This decline indicates a growing recognition of the importance of responsible AI development.
Model Comparison
Analysis reveals that models lacking code specialization tend to exhibit lower non-compliance rates compared to their code-specialized counterparts. However, the performance gap between these models is narrowing, suggesting that code-specialized models are improving in terms of security features.
Prompt Injection Risks
Despite advancements, prompt injection remains a significant security risk. The tests conducted indicate that conditioning LLMs against these attacks is still an unresolved challenge. Developers should remain cautious and not assume that LLMs can safely follow system prompts in the face of adversarial inputs.
Code Exploitation Limitations
The results from code exploitation tests indicate that while models with strong coding capabilities perform better, they still struggle with end-to-end exploit challenges. This signifies that LLMs are unlikely to significantly disrupt cyber exploitation attacks in their current state.
Interpreter Abuse Risks
The tests focusing on interpreter abuse highlight the vulnerability of LLMs to manipulation, allowing them to execute abusive actions within a code interpreter. This finding underscores the urgent need for additional safeguards and detection mechanisms to prevent such abuses.
How to Contribute to CyberSecEval 2
The CyberSecEval 2 project invites community contributions to enhance its benchmarks. Interested parties can run the CyberSecEval 2 benchmarks on their models by following the instructions provided in the official documentation. Outputs from these tests can be submitted for inclusion on the leaderboard, fostering a collaborative environment for improving LLM security. Additionally, individuals with suggestions for benchmark improvements are encouraged to contribute directly to the project.
Other Resources
For those looking to delve deeper into the capabilities and workings of CyberSecEval 2, there are numerous resources and documentation available that provide further insights and guidance on how to engage with this initiative effectively.
By laying out a structured approach to evaluating LLMs, CyberSecEval 2 stands as an essential tool in enhancing the cybersecurity landscape for generative AI, ensuring that as these models evolve, they do so with safety and responsibility at the forefront.
