AI-Powered Autonomous Cyberattacks: How DeepSeek and Hermes Agent Are Redefining Offensive Security

Artificial intelligence is rapidly transforming cybersecurity. While AI is helping defenders detect threats faster, cybercriminals are increasingly using the same technology to automate reconnaissance, vulnerability analysis, and attack execution.

A recent investigation by Palo Alto Networks Unit 42 revealed a sophisticated operation in which a Chinese-speaking threat actor leveraged the DeepSeek large language model through the Hermes Agent open-source framework to conduct largely autonomous cyberattack attempts. Instead of manually controlling every step, the operator simply initiated the campaign through Telegram, allowing the AI agent to perform much of the offensive workflow independently.

The incident highlights a significant shift in cyber operations: attackers are beginning to delegate technical decision-making to AI systems.

How the AI-Powered Attack Worked

According to Unit 42 researchers, the attacker used Hermes Agent as an orchestration framework that combined AI reasoning, terminal access, internet connectivity, exploit retrieval, and automation capabilities.

After receiving an initial instruction through Telegram, the AI agent was able to:

• Search the internet for exposed systems
• Identify vulnerable software versions
• Retrieve public proof-of-concept exploits from GitHub
• Evaluate which vulnerabilities were worth targeting
• Switch strategies when an attack path failed
• Continue operating without further human interaction

This represents a major evolution from traditional automated scripts.

Instead of executing predefined instructions, the AI actively reasoned, adapted, and selected the next attack path based on available information.

From Human Operator to Autonomous Decision-Maker

Unlike classic malware that follows hardcoded logic, the AI agent demonstrated behavior closer to a human penetration tester.

Researchers observed that it:

• Verified software versions
• Compared exploit reliability
• Considered deployment scale
• Prioritized vulnerabilities based on exploitation potential
• Abandoned ineffective attack chains
• Selected alternative targets

Although the attacks were not fully successful, the operational model represents an important milestone in AI-assisted offensive security.

Targeted Technologies

The campaign focused primarily on publicly accessible enterprise platforms frequently used for automation and AI workflows.

Among them were:

• Langflow
• n8n
• Marimo
• Citrix NetScaler ADC
• NetScaler Gateway

These products are increasingly deployed in cloud-native environments, making them attractive targets when exposed directly to the internet.

Why Most Attacks Failed

One reassuring aspect of the investigation is that most exploitation attempts were unsuccessful.

The AI correctly identified vulnerable software versions but frequently encountered environmental conditions that prevented exploitation, including:

• Authentication requirements
• Disabled vulnerable features
• Missing configuration parameters
• Lack of publicly accessible workflows
• Secure deployment practices

This demonstrates that proper system configuration remains one of the strongest defenses against AI-assisted attacks.

The Real Security Problem

The most interesting discovery wasn't actually the AI.

Researchers uncovered that the attacker accidentally exposed their own operational infrastructure by launching a temporary HTTP server.

This mistake allowed investigators to recover valuable forensic evidence, including:

• API keys
• Target lists
• Exploit scripts
• Configuration files
• Shell history
• AI session logs
• Autonomous execution records

Ironically, operational security — not AI — became the weakest link in the campaign.

What Makes Hermes Agent Different

Hermes Agent is not malware.

It is an open-source automation framework capable of integrating large language models with external tools.

Its documented capabilities include:

• Terminal execution
• Internet searches
• Scheduled tasks
• Telegram control
• Custom reusable skills
• Autonomous workflows

When connected to reasoning models like DeepSeek, these capabilities create a system able to perform complex offensive tasks with minimal human supervision.

A Glimpse Into the Future of AI-Assisted Hacking

Although only three targets were reportedly confirmed as successfully compromised during the broader operation, the significance lies elsewhere.

The campaign demonstrates that attackers are beginning to treat AI as an operational teammate rather than a simple chatbot.

Future AI agents may become capable of:

• Automatically discovering zero-day vulnerabilities
• Building exploit chains
• Generating malware
• Adapting to defensive controls
• Selecting targets dynamically
• Conducting long-running campaigns with little human oversight

While today's systems still require human supervision, each new model increases the level of autonomy.

How Organizations Can Defend Themselves

This campaign reinforces several cybersecurity best practices.

Organizations should:

• Keep internet-facing services fully patched
• Remove unnecessary public exposure
• Secure workflow automation platforms
• Restrict notebook and AI development environments
• Continuously monitor for suspicious reconnaissance activity
• Audit API usage and authentication mechanisms
• Implement Zero Trust access controls
• Use Endpoint Detection and Response (EDR) solutions
• Monitor AI-enabled administrative tools for abnormal behavior

The faster organizations reduce their attack surface, the harder it becomes for autonomous AI systems to identify exploitable targets.

Why This Research Matters

This incident is important not because the AI successfully compromised hundreds of systems, but because it demonstrates a new operating model for cyber attackers.

Large language models are evolving beyond content generation into autonomous decision-making systems capable of planning, adapting, and executing multi-stage technical operations.

For cybersecurity professionals, the message is clear: future defenses must anticipate attackers that combine automation, reasoning, and persistence.

The age of AI-assisted cyber operations is no longer theoretical — it has already begun.

Final Thoughts

Artificial intelligence is reshaping both sides of cybersecurity.

While defenders gain powerful tools for threat detection and incident response, attackers are also discovering ways to automate reconnaissance, exploit selection, and attack orchestration. The DeepSeek and Hermes Agent campaign illustrates how AI can accelerate offensive operations without replacing human operators entirely.

Organizations that rely solely on traditional perimeter defenses may struggle against increasingly adaptive AI-driven threats. Continuous patch management, secure configurations, proactive monitoring, and Zero Trust architectures are becoming essential components of modern cyber resilience.

As AI capabilities continue to evolve, the cybersecurity community must prepare for a future where autonomous agents participate in both defending and attacking digital infrastructure. Staying informed and reducing the attack surface today will be critical to mitigating tomorrow's AI-powered cyber risks.
