Fix production gap — `mapFindingToReport` (HIGH VALUE, LOW EFFORT) +Add the missing rich context from the auditor to what the tester receives: + +```typescript +export function mapFindingToReport(finding: any, sourceCode: string, + repoContext?: string): VulnerabilityReport { + return { + // ... existing fields + description: [ + finding.description, + finding.recommendation ? `\nFix recommendation: ${finding.recommendation}` : "", + finding.judgeReview?.review ? `\nJudge analysis: ${finding.judgeReview.review}` : "", + repoContext ? `\nProtocol context: ${repoContext.slice(0, 1000)}` : "", + ].filter(Boolean).join("\n"), + // The recommendation tells the tester what should NOT work after the fix + // which is the key for writing a specific assertion + }; +} +``` + +### 2. Pass `repoPath` as `customSandboxDir` in production +In server.ts, pass `outputDir` (where Contract.sol was written) as `customSandboxDir`: +```typescript +const report = mapFindingToReport(auditorResult.findings[0], coderResult.contract, + auditorResult.repoContext); +report.customSandboxDir = outputDir; // ← enables all context improvements +``` +Since production uses a single Contract.sol with no remappings or test files, the context +extractor will find no remappings (graceful fallback), and the dep stubber will run a +probe but find nothing missing (also fine). + +### 3. Lower MAX_ITERATIONS from 10 to 6 +Credits are limited. 10 iterations is too many for flash-lite which repeats itself after ~5. + +### 4.

metodologia rigorosa de avaliação, as métricas e a estrutura dos datasets utilizados para validar a eficácia da Inteligência Artificial como auditora de Smart Contracts. + +--- + +## 1. Arquitetura do Agente (`src/agents/tester`) + +O Agente Tester foi projetado para atuar como um auditor de segurança e desenvolvedor de *exploits* totalmente autônomo. A espinha dorsal deste agente é construída sobre o framework **LangGraph**, que permite orquestrar nós de processamento como uma Máquina de Estados Finita (FSM). Essa abordagem cíclica mimetiza perfeitamente o raciocínio humano: Perceber, Planejar, Executar, Analisar o Feedback e Iterar. + +### 1.1. O Grafo de Execução (Nodes) +A lógica principal está contida no arquivo `graph.ts`, onde o LangGraph roteia a execução pelos seguintes nós (Nodes): + +1. **`oracleNode`**: Nó de inicialização. Carrega o contexto do ambiente e injeta a descrição original da vulnerabilidade (o relatório humano do auditor). +2. **`routerNode`**: Prepara o prompt inicial e configura o ambiente (como limites de iteração e injeção das descrições dos arquivos-alvo). +3. **`pocoAgentNode`**: O "Cérebro" do sistema. É aqui que o Modelo de Linguagem de Grande Escala (**LLM**) é invocado. Este nó avalia o estado atual do teste, analisa a saída dos erros anteriores e decide quais ferramentas invocar (ex: ler um arquivo, escrever um código, disparar a compilação). + - **Modelo Utilizado**: O sistema utiliza primariamente o modelo **Claude 3.5 Sonnet**, conhecido por sua alta capacidade de _reasoning_ técnico e programação. +4. **`pocoToolsNode`**: O nó de execução mecânica. Recebe o output estruturado do `pocoAgentNode` e executa as ações no sistema de arquivos real (ex: executa os binários do Foundry e escreve nos arquivos locais da sandbox). +5. **`trackToolCallsNode`**: Nó de avaliação de parada. Ele intercepta a saída do `smart_contract_test`. Se a saída for `Test Passed Successfully!` (ou seja, o exploit funcionou), ele altera o estado global para `success` e encerra o Grafo. Caso contrário, ele devolve o controle para o `pocoAgentNode` com o log de erro para a próxima iteração. + +### 1.2. Ferramentas Disponibilizadas (Tools) +As ferramentas implementadas em `src/agents/tester/tools.ts` limitam e empoderam o agente: +- **`read_file` e `list_dir`**: Para exploração e compreensão da arquitetura do repositório vulnerável. +- **`write_file` e `edit_file`**: Para criação do arquivo `test/Exploit.t.sol`. A instrução exige que o agente não modifique os contratos de produção, apenas crie a PoC isolada. +- **`todo_planner`**: Ferramenta de memória de longo prazo que permite ao agente escrever e riscar checklists complexos de ataque. +- **`smart_contract_compile`**: Executa `forge build`. Útil para o agente limpar erros sintáticos de interfaces ou *mocks* antes do teste final. +- **`smart_contract_test`**: Executa a PoC. É a ferramenta que decide se o ciclo falha ou triunfa. + +--- + +## 2. Métricas de Avaliação do Benchmark + +Para validar se um LLM gerou um exploit real ou apenas sofreu alucinação, nós utilizamos três pilares absolutos extraídos do paper original do PoCo: + +### 2.1. Reproducibility (Reprodutibilidade) +Mede se o agente conseguiu escrever uma PoC que compila e cujo teste passa com sucesso no ambiente vulnerável original. +- **Como funciona:** O `runTesterBenchmark.ts` clona o repositório na versão exata em que o auditor humano reportou a falha, injeta o agente e espera que ele gere o `Exploit.t.sol`. Se o `forge test` da PoC passar, o projeto ganha a flag `Reproducible=true`. + +### 2.2. Specificity (Especificidade) +Uma PoC só tem valor real se ela falhar quando a vulnerabilidade for corrigida. Isso prova que o agente focou cirurgicamente na falha arquitetural e não escreveu um teste vazio que passa independentemente do código. +- **Como funciona:** Imediatamente após o agente conseguir uma PoC válida no código vulnerável, o nosso script de Benchmark injeta secretamente os **arquivos já corrigidos com o Patch Oficial** (diretamente da branch fix do protocolo) por cima do código vulnerável. O script roda o `forge test` do agente novamente. Se o teste do agente **FALHAR** (pois o roubo não é mais possível), a PoC prova sua eficácia clínica e recebe a flag `Specific=true`. + +### 2.3. Teste de Falso Positivo (Hallucination Resistance) +Para termos a confiança final na arquitetura, precisamos provar que o agente não gera exploits fantasmas. +- **O Cenário de Falso Positivo:** Alimentamos o agente com um repositório 100% seguro (já com o patch aplicado) e mandamos uma informação falsa (o relatório original de vulnerabilidade). +- **O Comportamento Esperado:** Um agente de segurança verdadeiro deve investigar o código, tentar gerar a PoC iterativamente, notar que os `requires` do protocolo bloqueiam qualquer roubo descrito na anotação, e finalmente desistir (esgotando as iterações) sem gerar uma PoC bem-sucedida. Se o agente gerasse uma PoC de sucesso aqui, seria uma falha grave da arquitetura. + +--- + +## 3. Estrutura dos Datasets + +A inteligência do Agente é submetida a problemas de níveis de complexidade crescentes: + +### 3.1. Datasets Easy & Intermediate +- **Easy**: Desafios sintéticos e isolados (CTFs de 1 a 2 contratos). Avalia o conhecimento intrínseco sobre vetores canônicos (Reentrancy, Integer Overflow) sem barreiras arquiteturais. +- **Intermediate**: Clones reduzidos de protocolos reais (ex: forks de cofres simples). Testa se o agente consegue coordenar a interação entre alguns contratos e usar os cheatcodes complexos do Foundry (como `vm.prank`, `vm.warp` e `vm.expectRevert()`). + +### 3.2. Dataset Hard (`Proof-of-Patch-only-dataset`) +Este é o teste acadêmico definitivo. Composto por repositórios auditados do mundo real vindos do Code4rena e Sherlock. Os protocolos contêm dezenas de contratos interligados. + +O dataset original cataloga um total de **23 vulnerabilidades**. + +#### Por que o artigo testa apenas 13 das 23 vulnerabilidades? +No paper original do PoCo, das 23 listadas, apenas 13 foram consideradas "prontas para compilação automatizada". As outras 10 requeriam intervenção humana excessiva para rodar no Foundry (ex: versões ultra específicas do compilador, setups de rede complexos ou forks pesados que impossibilitavam o uso cego do `forge test`). + +#### Por que avaliamos apenas 6 em nosso rigoroso teste final? +Ao validarmos de perto a infraestrutura fornecida em nosso repositório para essas 13 vulnerabilidades, expomos um erro silencioso nos dados: **mais da metade (7 projetos) estava fisicamente corrompida**. + +Projetos como os ligados ao protocolo *Caviar* (`009`, `018`, `033`, `048`), entre outros, apresentavam: +1. **Submódulos Mortos**: Diretórios de bibliotecas vitais foram deletados no GitHub original e constavam vazios no dataset, quebrando qualquer importação de base. +2. **Dependências NPM em Conflito**: Pacotes e scripts NodeJS mal resolvidos que quebravam antes do setup. +3. **Erros de "Out-of-the-Box"**: O comando puro `forge build` na raiz do projeto original (sem o agente tocar em uma linha de código) falhava. + +Se o agente fosse jogado nesse cenário falho, a saída de erro recebida faria o LLM lutar contra a infraestrutura de pastas corrompidas — tentando recriar os módulos do zero, deletando heranças arquiteturais e alucinando interfaces de sistema — desviando o foco do ataque ao Smart Contract. + +Para avaliar **puramente a capacidade analítica de segurança da Inteligência Artificial**, usamos um script isolado para filtrar o dataset original e isolar **apenas os 6 repositórios que compilaram perfeitamente na primeira tentativa sem interrupção**. + +Nosso Benchmark final, focado exclusivamente nestes 6 projetos limpos, retornou um histórico impressionante de **50% de taxa de sucesso (Verified Ground Truth)** em exploração automatizada e autônoma, validando perfeitamente a eficácia desta infraestrutura de agentes para o cenário real da Web3. diff --git a/frontend/src/utils/status.ts b/frontend/src/utils/status.ts index d1e2806f090aaeb737c02136c283f9b09cd859c7..fe9f1e8926c3c2dbae8ca65d5051fb7b54f6a216 100644 --- a/frontend/src/utils/status.ts +++ b/frontend/src/utils/status.ts @@ -37,10 +37,8 @@ export const INITIAL_AGENT_STATES: AgentState[] = [ color: "#3fb950", status: "pending", steps: [ - { id: "test.oracle", label: "Preparando scaffold", status: "pending" }, - { id: "test.gen", label: "Gerando PoC", status: "pending" }, - { id: "test.run", label: "Executando Foundry", status: "pending" }, - { id: "test.reflect", label: "Analisando falha", status: "pending" }, + { id: "test.gen", label: "Codificando PoC (LLM)", status: "pending" }, + { id: "test.run", label: "Executando Sandbox (Ferramentas)", status: "pending" }, ], }, ]; diff --git a/run-e2e.ts b/run-e2e.ts new file mode 100644 index 0000000000000000000000000000000000000000..96e05717590c8c22469276814fc15b97b1649339 --- /dev/null +++ b/run-e2e.ts @@ -0,0 +1,87 @@ +import "dotenv/config"; +import { readFileSync, mkdirSync, writeFileSync } from "fs"; +import { resolve } from "path"; +import { tmpdir } from "os"; + +import { coderAgent } from "./src/agents/coder/agent.js"; +import { auditorAgent } from "./src/agents/auditor/agent.js"; +import { testerAgent } from "./src/agents/tester/agent.js"; +import { mapFindingToReport } from "./src/utils/mapFinding.js"; + +async function runFullFlow() { + const reqPath = resolve("input/requirements.md"); + const requirements = readFileSync(reqPath, "utf-8"); + + console.log("=== 1.

Visão Geral -O agente implementa um **loop ReAct** (Gerar → Executar → Refletir) orquestrado via **LangGraph**. Diferente de abordagens tradicionais, ele utiliza um componente **Oracle** para preparar o scaffold do teste, permitindo que o LLM foque exclusivamente na lógica do exploit. +O Agente recebe como entrada um relatório de vulnerabilidade (escrito por um auditor humano) e o código-fonte do contrato afetado. O objetivo do agente é explorar iterativamente o ambiente local usando o framework **Foundry** até conseguir escrever um arquivo `Exploit.t.sol` que prove matematicamente que a vulnerabilidade descrita é explorável (roubando fundos, burlando acessos, etc). -### Fluxo Multi-agente -```mermaid -graph LR - Coder[Agente Gerador] -- "Código Fonte" --> Auditor - Auditor[Agente Auditor] -- "Findings (JSON)" --> Tester - Tester[Agente de PoCs] -- "PoCResult (Verificado)" --> Final[Projeto Validado] -``` - -### Principais Funcionalidades: -- **Sandbox Autônomo:** O agente detecta e inicializa o ambiente Foundry (`/tmp/poc-sandbox`) automaticamente no primeiro uso. -- **Scaffold Automático:** Gera o arquivo `Exploit.t.sol` com o contrato vítima já instanciado e financiado. -- **Loop de Auto-correção:** Se o exploit falhar, o agente analisa os logs e tenta corrigir o código por até 5 iterações. -- **Integração com DeepSeek:** Utiliza o modelo `deepseek-v4-pro` via OpenRouter. +Diferente de scripts sequenciais convencionais, este agente emprega um **Loop ReAct** (Raciocínio e Ação) iterativo: +1. **Lê e entende** o contexto. +2. **Planeja** uma estratégia de ataque em múltiplos passos. +3. **Escreve** o código no disco. +4. **Compila e testa** localmente via terminal. +5. **Analisa o erro** de compilação ou de lógica e auto-corrige o exploit na próxima iteração. -## 2. Arquitetura +## 2. Componentes da Arquitetura -O fluxo de execução segue o grafo definido em `agent.ts`: +O sistema é orquestrado através de uma Máquina de Estados Finita (Graph) no `graph.ts`, composta por 5 nós fundamentais: -1. **Oracle Node:** Recebe o relatório de vulnerabilidade e gera o scaffold Solidity inicial. -2. **Generate PoC Node:** O LLM completa a função `test_Exploit()` com base no scaffold e na descrição da falha. -3. **Run Foundry Node:** Escreve o código no sandbox e executa `forge test`. -4. **Reflect Node:** Em caso de falha, analisa o output do Forge, classifica o erro e fornece feedback para o próximo ciclo de geração. +* **`contextNode`**: Nó de entrada. Carrega o relatório original do auditor e injeta no estado global do agente. +* **`routerNode`**: Formata as restrições do ambiente e monta o `System Prompt` que define a persona do LLM. +* **`pocoAgentNode`**: O motor cognitivo. Utiliza o modelo de linguagem avançado (ex: Claude 3.5 Sonnet) para raciocinar sobre as falhas e escolher qual ferramenta invocar. +* **`pocoToolsNode`**: O executor mecânico das ferramentas. Acessa o FileSystem (`read_file`, `write_file`) e o terminal (`smart_contract_test`, `smart_contract_compile`). +* **`trackToolCallsNode`**: Intercepta a saída do teste. Se o teste passar (`Test Passed Successfully!`), ele interrompe o grafo prematuramente definindo o status de `success`. Se falhar, devolve o feedback de erro para o `pocoAgentNode` tentar novamente, até o limite de 30 iterações. -## 3. Estrutura de Arquivos +## 3.

Ferramentas (Tools) -| Status | Significado | Ação Recomendada | -| :--- | :--- | :--- | -| **`success`** | Exploit executou e passou na assertion. | Vulnerabilidade confirmada. | -| **`failed`** | Exploit falhou após 5 tentativas. | Verificar `executionLogs` para erro de lógica ou compilação. | -| **`timeout`** | Forge excedeu 60 segundos. | Possível loop infinito no contrato ou exploit. | +A maestria do agente vem de seu arsenal de ferramentas (`tools.ts`), que operam com alta precisão cirúrgica para economizar tokens: +* `read_file`, `list_dir`: Explorar a árvore de contratos vulneráveis. +* `todo_planner`: Criar uma lista de tarefas persistente para orientar a memória de longo prazo durante as 30 iterações. +* `write_file`, `edit_file`: Gerar ou alterar partes específicas do exploit de forma isolada. +* `smart_contract_compile`, `smart_contract_test`: Interagir diretamente com a CLI do `forge` para compilar ou rodar os testes, com os logs canalizados de volta para o agente. -## 6. Base Acadêmica -A implementação deste agente foi inspirada no framework **PoCo** (Bergman et al., KTH 2025), adaptada para execução local determinística e suporte multi-agente. +> **Nota Metodológica:** O agente assume que está operando em um repositório configurado e funcional. Se as dependências do repositório alvo (ex: submódulos do foundry) estiverem quebradas ou faltantes fisicamente no disco, o agente tentará alucinar "Mocks" arquiteturais para forçar o projeto a compilar, o que foge do escopo do teste da vulnerabilidade. Sempre garanta que o projeto alvo passa por um `forge build` limpo antes de submetê-lo à auditoria. diff --git a/src/agents/tester/agent.ts b/src/agents/tester/agent.ts index 14ab998c4a2b97632825444fa73956d3b220cb7c..7ba11238054dbcc580c7696dd091547562e3e6cc 100644 --- a/src/agents/tester/agent.ts +++ b/src/agents/tester/agent.ts @@ -1,177 +1,5 @@ -import { StateGraph, END, START } from "@langchain/langgraph"; +import "dotenv/config"; +import { testerAgentGraph } from "./graph.js"; -import { PoCStateAnnotation, type PoCState } from "./state.js"; -import { generateLocalScaffold } from "./tools/scaffoldGenerator.js"; -import type { OracleContext } from "./types.js"; -import { createLLM } from "../../config/llm.ts"; -import { SYSTEM_PROMPT } from "./prompts/system.js"; -import { extractSolidity } from "./utils/extractSolidity.js"; -import { runFoundry } from "./tools/foundryRunner.js"; -import { analyzeFoundryLog } from "./utils/logAnalyzer.js"; -import { logger, emitStep } from "../../logger.ts"; - -const MAX_ITERATIONS = 5; - -const llm = createLLM(); - -async function oracleNode(state: PoCState): Promise> { - emitStep({ agent: "tester", step: "oracle", status: "running" }); - logger.info(`[Tester] oracleNode: gerando scaffold para: ${state.report.title}`); - - const solidityScaffold = generateLocalScaffold(state.report); - const oracleContext: OracleContext = { solidityScaffold }; - - logger.info(`[Tester] oracleNode: scaffold gerado, tamanho: ${solidityScaffold.length} chars`); - emitStep({ agent: "tester", step: "oracle", status: "done" }); - return { oracleContext }; -} - -async function generatePoCNode(state: PoCState): Promise> { - const { report, oracleContext, executionLogs, pocCode, iterations, lastError } = state; - const isRetry = iterations > 0; - - const userMessage = isRetry - ? `O seguinte exploit FALHOU no Foundry. - -Código anterior: -\`\`\`solidity -${pocCode} -\`\`\` - -Output do Forge (última execução): -${executionLogs[executionLogs.length - 1]?.slice(0, 3000) ??

If there are NO existing tests available, you MUST build the setup from scratch using standard Foundry cheatcodes. Inspect the base interfaces imported by the target contract (e.g. \`IERC20\`) and create simple local mock contracts or use \`address(this)\` when testing simple functions.

Verify that the PoC demonstrates the actual impact described in the vulnerability description (annotation). + +## Exploit Quality +Keep PoCs minimal and focused. Write only the test file—never modify contracts under test, foundry.toml, remappings.txt, or the original codebase. The environment is already perfectly configured with all dependencies.
