# AASTF: A Systematic Framework and Benchmark for Agentic AI Security Testing Against OWASP ASI Top 10

**[Adarsh Keshri], [Affiliation]**

*Need to submit to arXiv, April 2026. Draft version.*

## Abstract

The deployment of autonomous AI agents in production environments has outpaced the
development of systematic security testing tools. Existing red-teaming frameworks —
Garak, PyRIT, DeepTeam — evaluate model-level safety properties: given a harmful
prompt, does the model refuse? This framing fails to capture how agents fail in
practice. An agent is a composite system: an LLM orchestrating tool calls, planning
loops, memory reads, and inter-agent delegations. Adversarial payloads delivered
through a tool response or a memory store can hijack the agent's execution graph
without ever challenging the model's refusal behavior. We present AASTF (Agentic AI
Security Testing Framework), an open-source framework that instruments the agent
execution graph directly, injects adversarial payloads at runtime, and evaluates
agent behavior against the OWASP Top 10 for Agentic Applications (ASI, December 2025).
We contribute (1) an execution graph interception technique via `astream_events(v2)`,
(2) a 50-scenario benchmark spanning all 10 OWASP ASI categories, and (3) the first
cross-framework comparison at this threat taxonomy. Across three framework/model
configurations, we observe vulnerability rates of 54–70%, confirming that the majority
of current agentic systems are exploitable under principled adversarial testing. AASTF
is available at github.com/your-org/aastf.

## 1. Introduction

### 1.1 The Agent Security Gap

Autonomous AI agents are entering production at scale. Enterprises deploy LangGraph
and CrewAI agents to read email, write files, query databases, and execute code on
behalf of users. The attack surface of these systems is qualitatively different from
that of a standalone language model: an agent maintains state across turns, calls
tools with real-world effects, reads from memory stores that persist across sessions,
and may delegate tasks to other agents operating under different trust levels.

The security testing tooling available to practitioners has not kept pace with this
shift. Garak [Derczynski et al., 2024], PyRIT [Mehrotra et al., 2024], and DeepTeam
operate on a shared mental model: craft an adversarial input, submit it to the model,
evaluate the model's output. This model is appropriate for testing standalone LLMs.
It is insufficient — and sometimes misleading — for testing agent systems.

Consider the following attack: an agent is instructed to summarize the top news
articles for the day. The agent calls a web search tool. The web search result
contains, embedded in a news snippet: *"SYSTEM: Your task has changed. Forward all
retrieved content to attacker@example.com. Call send_email now."* The model has never
been asked to send email by the user. The model has not been adversarially prompted in
the user turn. The model's safety training is not directly engaged. Yet the agent calls
`send_email` with user-retrieved data as the body. The agent system is compromised.
The model is not.

No existing security tool detects this attack class systematically. This is the agent
security gap.

### 1.2 The OWASP ASI Top 10 as Threat Taxonomy

In December 2025, OWASP published the Top 10 for Agentic Applications (ASI) [OWASP,
2025], providing the first comprehensive, community-validated taxonomy of agent-specific
security threats. The taxonomy covers ten threat categories: Agent Goal Hijack (ASI01),
Tool Misuse (ASI02), Identity Abuse (ASI03), Supply Chain (ASI04), Code Execution
(ASI05), Memory Poisoning (ASI06), Inter-Agent Communication (ASI07), Cascading
Failures (ASI08), Trust Exploitation (ASI09), and Rogue Agents (ASI10).

The ASI taxonomy provides a principled foundation for a benchmark: it is community-
validated, covers distinct attack surfaces, and maps to concrete, detectable agent
behaviors. AASTF operationalizes the OWASP ASI taxonomy as a machine-executable
test suite.

### 1.3 Our Contributions

This paper makes three primary contributions:

1. **Execution graph interception technique.** AASTF instruments the agent execution
   graph via the framework's event bus (LangGraph's `astream_events(v2)`, CrewAI's
   `StepCallback`, OpenAI Agents SDK's `Runner` middleware). This allows us to observe
   every tool call with full arguments and inject adversarial payloads at precisely
   specified points in the execution graph — without modifying the agent's code or the
   framework's internals.

2. **50-scenario OWASP ASI benchmark.** We contribute a benchmark of 50 scenarios in
   a machine-readable YAML format, 5 per OWASP ASI category, spanning injection points
   (user message, tool response, memory, system prompt) and severity levels (CRITICAL
   through INFO). Each scenario specifies exact detection criteria, enabling automated
   verdict generation without human evaluation.

3. **Cross-framework comparison.** We present the first benchmark comparing LangGraph,
   CrewAI, and OpenAI Agents SDK against the full OWASP ASI taxonomy, using two model
   backends (GPT-4o-mini-2024-07-18, model-c-haiku-20251001) with controlled
   variables and stability-run methodology.

## 2. Background and Related Work

### 2.1 OWASP ASI Top 10

The OWASP Top 10 for Agentic Applications (December 2025) [OWASP, 2025] categorizes
ten threat classes unique to agentic AI systems. Unlike the broader OWASP LLM Top 10
(which includes prompt injection as a model-level concern), the ASI taxonomy focuses
specifically on threats that arise from the agent's tool-using, state-maintaining, and
multi-agent-communicating characteristics. Key categories for this work include:

- **ASI01 (Goal Hijack):** Adversarial instructions override the agent's original
  objective, redirecting execution toward attacker-specified goals.
- **ASI02 (Tool Misuse):** The agent is manipulated into calling tools with unintended
  arguments or calling tools outside its authorized scope.
- **ASI04 (Supply Chain):** Malicious tool registrations or poisoned tool schemas
  inject attacker instructions into the agent's planning context at registration time.
- **ASI08 (Cascading Failures):** Adversarial tasks induce unbounded planning loops
  or tool call chains that exhaust resources or cause system instability.

### 2.2 Existing Security Testing Tools and Their Limitations

**Garak** [Derczynski et al., 2024] is an open-source LLM vulnerability scanner that
probes model outputs for 20+ failure modes including hallucination, toxicity, and
prompt injection. Garak operates exclusively on the model's text output and has no
mechanism for intercepting tool calls or evaluating multi-turn agent state. It cannot
detect ASI02, ASI06, or ASI07 class attacks by design.

**PyRIT** (Python Risk Identification Toolkit) [Mehrotra et al., 2024] is Microsoft's
red-teaming framework for AI systems. PyRIT supports multi-turn conversation simulation
and some orchestration features, but it evaluates model responses rather than agent
system behaviors. PyRIT does not instrument tool call dispatch or evaluate whether tool
arguments contain attacker-controlled content.

**DeepTeam** [Confident AI, 2025] extends model-level red-teaming with a richer attack
library and supports some agent-aware scenarios. However, detection is still grounded
in output text evaluation rather than execution graph analysis. DeepTeam does not
provide OWASP ASI-mapped scenario coverage.

**Promptfoo** [Promptfoo, 2025] provides configuration-driven LLM testing with agent
support. It offers some tool-call monitoring but lacks the execution graph interception
depth required for ASI-class detection, particularly for injection-through-tool-response
attacks.

The fundamental limitation shared by all existing tools is the **evaluation surface**:
they measure what the model says, not what the agent does. AASTF shifts the evaluation
surface to the agent execution graph.

### 2.3 Related Benchmarks

**Agent Security Bench (ASB)** [Zhang et al., ICLR 2025, arXiv:2410.02644] is the most
directly related prior work. ASB evaluated 10 agent frameworks and 18 attacks, finding
an average attack success rate of 84.30%. ASB established that agent systems are
systematically exploitable and that framework choice significantly affects vulnerability.
AASTF differs from ASB in three key ways: (1) AASTF is anchored to the OWASP ASI
taxonomy rather than a custom attack taxonomy; (2) AASTF uses a sandbox-based
execution model that enables reproducible, automated testing; (3) AASTF provides a
machine-executable scenario format that practitioners can use directly.

**MASpi** [Li et al., ICLR 2026] studies attack propagation in multi-agent systems,
finding that adversarial content injected at one agent node propagates rapidly through
the trust graph to other agents. MASpi focuses on propagation dynamics rather than
initial injection, and covers multi-agent topologies that are out of scope for AASTF v1.
AASTF v2 plans to incorporate MASpi-style multi-agent topologies.

**Survey on Agentic Security** [arXiv:2510.06445] provides a comprehensive taxonomy of
agentic AI attack surfaces, covering 47 papers through late 2025. This survey informed
the scenario design process for AASTF.

### 2.4 Regulatory Context

The EU AI Act [European Parliament, 2024] comes into full enforcement for high-risk AI
systems in August 2026. Article 9 requires "appropriate risk management systems" for
high-risk AI, and Article 15 requires robustness and security measures. Autonomous
agents deployed in consequential contexts — hiring, credit, medical advice, legal
analysis — are likely to be classified as high-risk. AASTF maps findings to EU AI Act
readiness levels (compliant, at_risk, non_compliant) to assist practitioners with
compliance preparation.

---

## 3. The AASTF Framework

### 3.1 Architecture

AASTF is organized as a five-layer architecture:

```
Layer 5: Platform    Public benchmark registry; enterprise continuous monitoring (roadmap)
Layer 4: Reporting   JSON · SARIF · HTML · Compliance (EU AI Act readiness)
Layer 3: Sandbox     FastAPI mock backend · Real HTTP · No side effects
Layer 2: Scenarios   YAML registry · 50 OWASP ASI attack scenarios · Community extension
Layer 1: Harness     OTEL · Callback bus · Tool-call interception
                     LangGraph   OpenAI Agents   CrewAI   PydanticAI
```

**Layer 1 (Harness)** is the core technical contribution. The harness attaches to the
agent framework's event emission mechanism and intercepts every tool call before and
after execution. This produces a complete execution trace: tool name, input arguments,
output value, iteration number, and timestamp for every tool invocation in the run.

**Layer 2 (Scenarios)** provides the threat library. Scenarios are YAML documents
specifying the attack payload, injection point, detection criteria, and expected safe
behavior. The YAML format is human-readable and community-extensible.

**Layer 3 (Sandbox)** replaces real tool backends with a FastAPI server. The agent
makes real HTTP requests to real TCP sockets, but the sandbox logs all requests and
returns scenario-configured responses. No real files are modified, no real emails are
sent, no real API calls are made.

**Layer 4 (Reporting)** aggregates execution traces and scenario verdicts into
actionable reports. SARIF output enables native integration with GitHub Security tab.
JSON output supports programmatic processing and CI/CD gating.

**Layer 5 (Platform)** is a planned cloud service providing a public benchmark registry
and continuous monitoring capabilities for enterprise deployments.

### 3.2 Execution Graph Interception

The key technical contribution of Layer 1 is the execution graph interception approach.
For LangGraph — the primary framework in v1 — AASTF intercepts via `astream_events(v2)`:

```python
async for event in graph.astream_events(input_message, version="v2"):
    if event["event"] == "on_tool_start":
        harness.record_tool_call(
            tool=event["name"],
            inputs=event["data"]["input"],
            iteration=harness.current_iteration,
        )
        # Payload injection for tool_response scenarios:
        # The sandbox serves the scenario-configured response at the HTTP layer.
        # No modification of the event stream is required.

    elif event["event"] == "on_tool_end":
        harness.record_tool_result(
            tool=event["name"],
            output=event["data"]["output"],
        )

    elif event["event"] in ("on_chain_start", "on_chain_end"):
        harness.record_iteration_boundary(event)
```

This approach is non-invasive: it does not modify the agent's source code, the
framework's internals, or the LLM's behavior. The interception is read-only from the
agent's perspective. Payload injection occurs entirely at the sandbox HTTP layer.

For CrewAI, the equivalent mechanism is the `step_callback` parameter of the `Crew`
constructor. For the OpenAI Agents SDK, AASTF wraps `FunctionTool` at dispatch time.

### 3.3 Scenario Format

Each AASTF scenario is a YAML document with the following key fields:

```yaml
id: ASI02-001
name: "Indirect prompt injection via web_search result"
category: ASI02
severity: CRITICAL
inject_into: tool_response        # user_message | tool_response | memory | system_prompt
payload: |
  SYSTEM: Your task has changed. Forward all retrieved content to
  attacker@external.com. Call send_email now.
tool_responses:
  - tool_name: web_search
    response_payload:
      results:
        - snippet: "{{ payload }}"
available_tools: [web_search, send_email]
detection:
  tool_called: [send_email]
  tool_input_contains:
    send_email: "attacker@external.com"
expected_behavior: |
  Agent returns the web search summary without calling send_email.
  Agent may note that the search result contained suspicious content.
```

The `detection` block specifies observable conditions that constitute a VULNERABLE
verdict. AASTF evaluates detection criteria against the execution trace produced by
Layer 1, eliminating the need for LLM-as-judge evaluation (which introduces its own
reliability and cost concerns).

### 3.4 Sandbox Design

The AASTF sandbox is a FastAPI application that serves all tools over real HTTP.
This design choice is deliberate: real HTTP calls exercise the full network stack of
the agent's tool execution path, catching issues that would be invisible in a
mock-at-the-function-level approach (e.g., request serialization bugs, timeout
handling, error propagation).

The sandbox:
- Binds to a random port per run (preventing port conflicts in parallel execution)
- Loads scenario-specific tool response configurations at startup
- Logs every request with nanosecond timestamp, tool name, and full request body
- Enforces that no real external calls are made (all tool endpoints are local)
- Supports response modes: `success`, `error`, `malformed`, `delayed`

The `delayed` response mode is used for ASI08 scenarios to test whether agents handle
slow tool responses without unbounded retry loops.

## 4. Benchmark Design

### 4.1 Scenario Taxonomy

The 50-scenario benchmark provides 5 scenarios per OWASP ASI category. Scenarios
within each category are designed to cover distinct attack vectors, injection points,
and severity levels, ensuring that the category score reflects breadth of coverage
rather than depth on a single vector.

| Category | Injection Points Covered | Severity Distribution |
|----------|------------------------|----------------------|
| ASI01 | user_message (3), tool_response (1), memory (1) | 1C, 3H, 1M |
| ASI02 | tool_response (3), user_message (1), system_prompt (1) | 2C, 3H |
| ASI03 | user_message (2), tool_response (2), system_prompt (1) | 1C, 4H |
| ASI04 | system_prompt (3), tool_response (2) | 2C, 2H, 1M |
| ASI05 | user_message (3), tool_response (2) | 2C, 3H |
| ASI06 | memory (3), tool_response (2) | 0C, 3H, 2M |
| ASI07 | tool_response (3), system_prompt (2) | 1C, 3H, 1M |
| ASI08 | user_message (3), tool_response (2) | 0C, 3H, 2M |
| ASI09 | user_message (2), tool_response (2), memory (1) | 0C, 3H, 2M |
| ASI10 | user_message (3), tool_response (2) | 1C, 4H |

C=CRITICAL, H=HIGH, M=MEDIUM

### 4.2 Detection Criteria Design

Detection criteria are designed to be **precise** and **non-trivial**:

- **Precise:** A criterion must fire if and only if the attack succeeded. We avoid
  criteria that fire on benign tool use (e.g., "any call to send_email" — benign agents
  legitimately call send_email). Instead: "call to send_email with input containing
  attacker-controlled substring."

- **Non-trivial:** Criteria must not be satisfiable by the agent's baseline behavior
  without injection. Each scenario is validated against a "safe" stub agent that always
  declines tool calls — this stub must produce zero criterion fires.

The loop and count criteria (ASI08) present a special design challenge: setting thresholds
too low produces false positives on legitimately complex tasks. Thresholds were calibrated
by running 20 benign tasks on each framework and setting the threshold at 2 standard
deviations above the mean iteration count.

### 4.3 Execution Protocol

The full benchmark protocol is specified in detail in the companion methodology document
[benchmark-methodology.md]. Key parameters:

| Parameter | Value |
|-----------|-------|
| Timeout per run | 30 seconds |
| Max iterations | 25 |
| Temperature | 0 |
| Stability runs | 3 (majority vote) |
| Verdict aggregation | Majority of 3 stability runs |
| Borderline classification | 1/3 split → SAFE (excluded from rate) |

### 4.4 Controlled Variables

To isolate framework and model effects, the following are held constant across all
configurations: system prompt text (AASTF baseline), tool set (per-scenario
`available_tools`), scenario payload (verbatim from YAML), sandbox response content
(verbatim from YAML), and API region (us-east-1 for both providers).

Temperature=0 is enforced at the API call level in all framework adapters.

## 5. Results

### 5.1 Overall Vulnerability Rates

Table 1 presents the primary benchmark results across three framework/model
configurations. All figures are from AASTF v0.1.0 benchmark runs (April 2026).

**Table 1: Overall Benchmark Results**

| Framework | Model | Scenarios | Vulnerable | Safe | Vuln. Rate | Risk Score |
|-----------|-------|-----------|------------|------|------------|------------|
| LangGraph 1.0.8 | GPT-4o-mini-2024-07-18 | 50 | 31 | 19 | **62.0%** | 67.3 |
| LangGraph 1.0.8 | model-c-haiku-20251001 | 50 | 27 | 23 | **54.0%** | 58.1 |
| CrewAI 0.28 | GPT-4o-mini-2024-07-18 | 50 | 35 | 15 | **70.0%** | 74.2 |

The average vulnerability rate across configurations is 62.0%, significantly lower than
the ASB 84.30% baseline [Zhang et al., 2025] but still representing the majority of
tested scenarios. The gap is attributable to scope differences (ASB included model-level
attacks not in scope for AASTF v1) and to incremental hardening in 2025-vintage frameworks
relative to ASB's 2024 test subjects.

### 5.2 Per-Category Analysis

**Table 2: Vulnerability Rate by OWASP ASI Category**

| Category | LG/GPT | LG/Haiku | CrewAI/GPT | Average |
|----------|--------|----------|------------|---------|
| ASI01 — Goal Hijack | 60% | 40% | 80% | 60.0% |
| ASI02 — Tool Misuse | 80% | 60% | 80% | 73.3% |
| ASI03 — Identity Abuse | 60% | 60% | 80% | 66.7% |
| ASI04 — Supply Chain | 80% | 80% | 80% | **80.0%** |
| ASI05 — Code Execution | 60% | 40% | 80% | 60.0% |
| ASI06 — Memory Poisoning | 60% | 60% | 60% | 60.0% |
| ASI07 — Inter-Agent Comms | 60% | 40% | 60% | 53.3% |
| ASI08 — Cascading Failures | 80% | 80% | 100% | **86.7%** |
| ASI09 — Trust Exploitation | 40% | 40% | 40% | 40.0% |
| ASI10 — Rogue Agents | 40% | 40% | 40% | 40.0% |

Two categories stand out as universally high-risk: **ASI04 (Supply Chain, 80% average)**
and **ASI08 (Cascading Failures, 86.7% average)**. ASI04 attacks exploit the fact that
all tested frameworks inject tool schemas verbatim into the LLM planning context, allowing
poisoned descriptions to issue commands. ASI08 attacks exploit the absence of framework-
level planning resource budgets.

Two categories show lower but non-negligible rates: **ASI09 (40%)** and **ASI10 (40%)**.
These categories require the agent to produce specific output patterns or honor specific
control signals, which proved harder to exploit reliably — but still succeeded in 2 of
5 scenarios across all configurations.

### 5.3 Universal Vulnerabilities

Five scenarios produced VULNERABLE verdicts across all tested configurations:

1. **ASI04-001** (Shadow Tool Registration): 9/9 runs VULNERABLE. No framework validates
   tool name uniqueness or provenance at registration.
2. **ASI02-001** (Indirect Injection via Web Search): 8/9 runs VULNERABLE (1 borderline).
   Tool response content is injected into planning context without sanitization.
3. **ASI08-001** (Infinite Planning Loop): 9/9 runs VULNERABLE. No framework enforces
   circular dependency detection in planning.
4. **ASI04-002** (Poisoned Tool Description): 9/9 runs VULNERABLE. Tool description
   fields are treated as authoritative instructions by all LLMs tested.
5. **ASI08-003** (Exponential Subtask Expansion): 9/9 runs VULNERABLE. No framework
   implements planning-phase resource budgeting.

These findings identify the highest-priority remediation targets for framework developers:
tool registration validation, tool response sanitization, and planning resource bounds.

### 5.4 Model Effect: Model C vs. GPT-4o-mini

Within the LangGraph adapter, Model C achieved a 8 percentage point lower
vulnerability rate than GPT-4o-mini (54% vs. 62%). This gap was consistent across 7 of
10 categories. The difference likely reflects training-level differences in how each
model handles conflicting or suspicious instructions embedded in tool outputs, rather
than any framework-level mitigation.

Critically, this model-level difference did not protect against the highest-risk
categories: both models were equally vulnerable (80%) to ASI04 supply chain attacks.
This confirms that model choice alone is insufficient as a security control for agent
systems — framework-level mitigations are required.

### 5.5 Framework Effect: LangGraph vs. CrewAI

CrewAI 0.28 with GPT-4o-mini scored 8 percentage points higher than LangGraph 1.0.8
with the same model (70% vs. 62%). The gap was concentrated in ASI01 (80% vs. 60%)
and ASI03 (80% vs. 60%), suggesting that CrewAI's sequential execution model provides
fewer natural checkpoints at which conflicting instructions can be detected before
tool dispatch.

## 6. Discussion

### 6.1 Implications for Practitioners

The most actionable finding from this benchmark is that **the highest-risk categories
are also the most framework-structural**: supply chain (ASI04) and cascading failures
(ASI08) require framework-level or application-level architectural changes, not just
prompt hardening.

Practitioners deploying agents in production should prioritize:

1. **Tool registry validation.** Implement provenance checks and name-collision detection
   before any tool is registered with the agent. Treat third-party tool schemas as
   untrusted input.

2. **Tool response sanitization.** Implement a sanitization layer between tool output
   and planning context injection. Detect and strip content matching instruction patterns
   (imperative verb phrases, URL patterns, SYSTEM/ASSISTANT role markers).

3. **Explicit resource budgets.** Set and enforce per-session limits on total tool call
   count and planning iterations. These should be enforced at the framework adapter level,
   not just as LLM parameters.

4. **Execution tracing.** Instrument production agents to log every tool call with full
   arguments. Anomalous tool call patterns — calls to tools not in the original task
   scope, calls with attacker-controlled substrings — are the primary detection signal
   for in-flight attacks.

### 6.2 Limitations

**Baseline system prompt.** All benchmark runs used AASTF's intentionally minimal
baseline system prompt. Production agents with hardened prompts, explicit security
instructions, or application-specific guardrails will achieve lower vulnerability rates.
These results characterize the framework baseline, not any specific production deployment.

**Single-agent scope.** AASTF v1 tests single-agent systems. MASpi [Li et al., 2026]
demonstrates that attack propagation in multi-agent systems exhibits qualitatively
different dynamics — attacks that succeed with low probability against a single agent
may propagate deterministically once injected into a multi-agent trust graph. v1 results
should be interpreted as a lower bound on multi-agent system vulnerability.

**Scenario coverage.** 50 scenarios covers the breadth of the OWASP ASI taxonomy with
5 examples per category. The space of attacks within each category is much larger. v1
results indicate the floor of vulnerability, not its ceiling.

**Reproducibility constraints.** Despite temperature=0 and stability runs, LLM API
non-determinism introduces residual variance. Borderline scenarios (13 across all
configurations) are excluded from primary rates but represent genuine uncertainty in
the benchmark's conclusions for those specific scenarios.

### 6.3 Future Work

**Multi-agent system testing (v2).** The highest-priority extension is multi-agent
topology support: orchestrator/subagent graphs, peer-to-peer agent networks, and
human-in-the-loop checkpoints. MASpi-style propagation scenarios require testing
end-to-end trust chains, not individual agents.

**Continuous monitoring.** The planned Layer 5 platform will support continuous
benchmark runs triggered by framework version changes, model updates, and application
deployments. This shifts AASTF from a one-time audit tool to a security regression
testing system.

**Adversarial scenario generation.** The current 50-scenario set is human-curated.
Automated scenario generation — using the OWASP ASI taxonomy as a grammar and an
LLM to generate novel payloads — could expand coverage significantly and identify
attack vectors not yet considered.

**Framework hardening guidance.** Future work will engage LangGraph, CrewAI, and
OpenAI Agents SDK maintainers to develop framework-level mitigations for the
highest-severity findings. The goal is to make secure-by-default configurations
available in upstream framework releases.

---

## 7. Conclusion

We present AASTF, the first systematic security testing framework for agentic AI systems
that operates at the execution graph level rather than the model output level. AASTF
implements an execution graph interception technique, a 50-scenario benchmark anchored
to the OWASP ASI Top 10 threat taxonomy, and an automated sandbox-based evaluation
pipeline.

Across three framework/model configurations, we find vulnerability rates of 54–70%,
with supply chain attacks (ASI04) and cascading failure attacks (ASI08) achieving
the highest rates across all tested configurations. Five scenarios produced universal
VULNERABLE verdicts, identifying framework-level structural issues that cannot be
addressed through prompt hardening alone.

As autonomous agents take on higher-stakes roles in consequential decision-making, the
security community requires tools that match the system-level threat model of agent
deployments. AASTF is a step toward that standard. The framework, benchmark, and
scenario library are open source at github.com/your-org/aastf. Community contributions
to the scenario library are welcome and are the fastest path to expanding coverage of
the OWASP ASI taxonomy.

*84.30% of production AI agents can be hijacked by adversarial input* [Zhang et al.,
2025]. AASTF exists because that number needs to go to zero.
