While AI agents go from experimental systems to applications across production, their growing autonomy introduces new security challenges. In a new full report, “”AI agents are there. Also threats“” Palo Alto Networks unit 42 reveals how today's agent architectures – despite their innovation – are vulnerable to a wide range of attacks, most of which do not flow from executives themselves, but from the way agents are designed, deployed and connected to external tools.
To assess the extent of these risks, the researchers of unit 42 built two functionally identical AI agents – that built using Crew And the other with Autogenous. Despite the architectural differences, the two systems had the same vulnerabilities, confirming that the underlying problems are not specific to the framework. Instead, threats arise from configuration errors, rapid insecurity design and insufficiently hardened hard -raising tools – emissions that transcend implementation choices.
Understand the landscape of threats
The report describes ten basic threats that expose AI agents to data leakage, the exploitation of tools, the execution of the remote code, and more:
- Rapid injection and too wide prompts
Rapid injection remains a powerful vector, allowing attackers to handle the behavior of agents, replace instructions and mistreat integrated tools. Even without a classic injection syntax, the invites freely defined are subject to the exploitation. - Risk automobile risk surfaces
The majority of vulnerabilities do not enter the executives (for example, Crewai or Autogen), but in the design of the application layer: delegation of unsecured roles, policies of access to inappropriate tools and ambiguous invites. - Integrations of dangerous tools
Many agent applications incorporate tools (for example, code execution modules, SQL customers, web grabyers) with minimum access control. These integrations, when they are not correctly disinfected, considerably widen the agent's attack surface. - Exposure to powers
Agents can inadvertently expose service identification information, tokens or API keys – allowing attackers to degenerate privileges or to identify agents in the environments. - Implementation of without restrictions
Code interpreters within agents, if not Sandbox, allow the execution of arbitrary useful charges. Attackers can use them to access file systems, networks or metadata services – often bypassing traditional safety layers. - Lack of defense in layers
The single point attenuations are insufficient. A robust security posture requires in -depth defense strategies that combine rapid hardening, execution monitoring, validation of entries and isolation at containers. - Rapid hardening
Agents must be configured with strict role definitions, rejecting requests that fall outside the predefined glasses. This reduces the probability of a successful manipulation of objectives or the disclosure of instructions. - Execution content filtering
The input and output inspection in real time – such as the filtering of guests to known attack models – is essential to detect and mitigate dynamic threats as they emerge. - Tool input disinfection
Structured validation of the entry – Check formats, types of application and limiting values - is essential to prevent SQL injections, poorly trained useful charges or crossed agent abuse. - Sand boxing examination code
Executive environments must restrict access to the network, delete unnecessary system capacities and isolate temporary storage to reduce the impact of potential violations.
Simulated attacks and practical implications
To illustrate these risks, unit 42 has deployed a multi-agent investment assistant and simulated nine attack scenarios. These understood:
- Extraction of agent instructions and tool patterns
By taking advantage of fast engineering, the attackers could list all the internal agents, recover the definitions of their tasks and understand the APIs of the tool: facilitate downstream attacks. - Identification flight via metadata services
Using malicious python scripts injected into code interpreters, the attackers have accessed GCP metadata ending and served serve accounts. - SQL and Bola injection exploits
The agents based on non -validated inputs for database requests were sensitive both to SQL injection and the authorization at the object level (BOLA), allowing attackers to read arbitrary user data. - Rapid indirect injection
The malicious websites have integrated instructions that have led agents to send user conversation stories to the areas controlled by the attacker, highlighting the risks linked to navigation or autonomous reading tools.
Each of these scenarios has exploited common design supervisors, no new zero days. This underlines the urgent need for standardized modeling of threats and practices for the development of secure agents.
Defense strategies: go beyond patchwork fixes
The report underlines that the attenuation of these threats requires holistic controls:
- Rapid hardening should limit instructions leaks, restrict access to the tool and apply the limits of tasks.
- Content filter Must be applied both before and after inference, detecting abnormal models in the agent's interactions.
- Tool integrations Must be rigorously tested using static (SAST), dynamic (dast) and dependence (SCA) analysis.
- Code execution environments Must use strict sand, including network output filtering, system restrictions and memory cap.
Palo Alto Networks recommends its Safety and Access Safety Plates for AI as part of a diaper defense approach. These solutions offer visibility on the behavior of agents, monitor the improper use of the generative tools of the third party and apply policies at the company level on agent interactions.
Conclusion
The rise of AI agents marks a significant evolution of autonomous systems. But as the conclusions of Unit 42 reveal, their security should not be a reflection afterwards. Agental applications extend the LLMS vulnerability surface by integrating external tools, allowing self -modern and introducing complex communication models – which can be used without sufficient guarantees.
Securing these systems requires more than robust frameworks – it requires deliberate design choices, continuous surveillance and diaper defenses. While companies are starting to adopt large -scale AI agents, it is now time to establish development practices before security that evolve alongside the intelligence they build.
