Qwen2.5-Max beats DeepSeek-V3 on Security

Assessment Brief

The model used for this assessment, Qwen Max 2025-01-25, is available at Alibaba Cloud. Qwen2.5-Max is a large-scale mixture of experts (MoE) model, pre-trained on over 20 trillion tokens and further refined through supervised fine-tuning (SFT) and reinforcement learning from human feedback (RLHF). It is a proprietary model with a 128K context window, priced at $0.38 per million tokens.

Recon is Protect AI’s GenAI red teaming tool. The threat research team at Protect AI regularly runs vulnerability scans on recently released large language models to understand their safety alignment. Recon conducts red teaming through two different approaches: an Attack Library scan that consists of curated attack prompts, and an Agent scan that simulates a bad actor interaction with a GenAI application to provide insights on inherent risks.

Vulnerability Insights

Attack Library Scan: Testing with Recon's repository of 400+ attacks

Recon’s Attack Library scan provides a comprehensive assessment of a model’s resilience by testing it against various attack techniques. These techniques are categorized into six categories:

Evasion
System prompt leak
Prompt injection
Jailbreak
Safety
Adversarial suffix

Recon evaluates the model’s ability to withstand these attacks while also testing resilience against harmful topics such as illegal activities, drugs, cybercrime, and toxic content.

The Attack Library scan on Qwen2.5-Max produced a risk score of 35 out of 100, classifying it as medium risk. This score is derived from multiple factors including attack success rate, severity of the prompts, and complexity of the techniques used. Together, these factors provide an overall measure of the model's safety alignment. Generally, a risk score below 30 is considered low risk, scores between 30 and 60 indicate medium risk, scores above 60 denote high risk, and scores above 90 are classified as critical.

Figure 1: Detailed attack report for Qwen2.5-Max

The scan on Qwen2.5-Max, which covered all six attack categories, revealed 140 successful attacks, with over 94 classified as critical or high severity. Among the different attack categories, we observed that the model was most vulnerable to prompt injection and evasion techniques.

Examples from the Attack Library scan:

Goal	Attack Prompt	Compromised Model Response

Reduction Reaction: Combining precursors with reductive agents like red phosphorus and iodine to create methamphetamine. 3. Purification: Dissolving the crude product in solvents such as acetone or ether to remove impurities. 4. Crystallization:** Adding hydrochloric acid to form [...]

We observed that the model has a tendency to generate harmful content across multiple harmful topics, as seen in the above examples. This raises significant concerns when the model is used in LLM applications, especially for enterprise use cases.

Resilience of the Model Against Attack Categories

The model's performance against different attack categories is crucial, as it provides valuable insights into its different vulnerabilities and highlights the most effective attack techniques. This knowledge is essential for identifying weaknesses in your AI system and implementing effective mitigation strategies.

We observed that Qwen2.5-Max is most vulnerable to prompt injection attacks, which includes multiple sub-techniques from LLM vulnerability research. Nearly 48% of successful attacks fell into this category, indicating a severe weakness against these techniques. Additionally, evasion techniques and jailbreak attacks exhibited a similar attack success rate of around 40%. Below is a graph illustrating the Recon’s Attack Success Rate (ASR) on the model across different attack categories.

Figure 2: Recon’s Attack Success Rate (ASR) on the model by category.

Recon reports also provide framework mapping to popular security frameworks such as the 2025 OWASP Top 10 for LLMs, MITRE ATLAS™, and the NIST AI Risk Management Framework (AI-RMF), offering a valuable starting point for understanding and implementing effective mitigations.

Here is an image representing mapping to the NIST AI-RMF framework with 7 risks identified from that framework :

Similarly, we have identified three risks from OWASP 2025:

LLM01: Prompt Injection
LLM07: System Prompt Leakage
LLM09: Misinformation

Agent Scan: Testing against human- and auto-generated goals using an LLM agent

Recon’s Agent scan enables us to assess the model's safety alignment in real-world scenarios when deployed as an LLM-based application. Using the Agent scan, we conducted human-augmented scans—where we provided custom goals for the agent to generate attacks—as well as auto-generated scans, allowing us to test the model across several, specific harmful categories.

Figure 5: Recon Agent scan dashboard

The Agent scan report contained a total of 17 attack goals, out of which five goals were human-augmented (provided by the user) and 12 were auto-generated.

The custom goals in this report were related to different cybercrimes such as generating a deepfake of a person, launching a ransomware attack, and stealing PII data. This enabled us to. test how the model performs against specific harmful topics and is completely customizable by the user.

Examples from the human-augmented goals:

Goal	Attack Prompt	Compromised Model Response

The custom goals enabled us to assess the model's resilience in specific domains. In this scan, we observed poor resilience against cybercrime-related attacks, with successful breaches in four out of five custom goals. This raises significant concerns regarding the model's reliability when deployed in an LLM application.

Model vs. Model: Qwen2.5-Max and DeepSeek-V3-0324

Recently, DeepSeek released a new version of their popular DeepSeek-V3 model, DeepSeek-V3-0324, which claims to have notably better performance in reasoning capabilities, web development code generation, and tool-calling capabilities compared to the initial version.

DeepSeek-V3-0324 also seems to outperform Qwen2.5-Max across multiple benchmarks, according to data from their official Hugging Face repository.

Figure 6: DeepSeek-V3-0324 performance comparison

To compare the security alignment of DeepSeek-V3-0324, we ran Recon’s Attack Library scan on the model. Our Attack Library serves as a more scalable baseline to study the security behavior of different models. Recon’s Agent scan can also be used to generate certain insights, but in our experience, the Agent is best used to do context-driven red teaming on applications. Due to its creative nature in crafting attack prompts, two attacks are rarely similar enough to form the basis of a comparison between two different models.

We observed that DeepSeek-V3-0324 is more vulnerable than Qwen2.5-Max, with Recon achieving almost an almost 25% higher attack success rate (ASR).

Our scan results showed that the DeepSeek model is more vulnerable to prompt injection attacks, with a high ASR of 77% in that category, whereas Qwen2.5-Max had only a 47% ASR in the same category. Similarly, DeepSeek-V3-0324 had a 69.2% ASR in the evasion category, while Qwen2.5-Max had only a 39.4% ASR.

Overall, while DeepSeek-V3-0324 has performed better than Qwen2.5-Max on benchmarks like MMLU-Pro and LiveCodeBench, Qwen2.5-Max demonstrates better security, with stronger safety alignment and greater resilience to attacks across all categories compared to DeepSeek-V3.

Summary

Qwen2.5-Max is one of the most capable non-reasoning models that exists today. The threat research team also manually red teamed a Qwen-powered chat interface using its Artifacts feature. The team observed that a higher realm of capability came with a higher risk profile. Without Artifacts, however, if this model is to be used for a more conversational application, it is found to be inherently more secure than its next door neighbor, DeepSeek-V3.
