macOS Sandbox Testing Prompts
Generated: 2026-04-09 Based on:
sandbox-whitelist-blacklist-plan.md+acpTerminalManager.ts+sandboxMatrix.tsimplementation Platform: macOS (darwin)
测试路径与沙箱模式覆盖
两条测试路径
| 测试路径 | 模式 | 沙箱层 | 权限层 | 说明 |
|---|---|---|---|---|
| A. ACP 会话 | 由 Agent Runner 配置 | ❌ 不走 seatbelt | ✅ 生效 | 通过 QimingClaw 客户端 ACP session 发送提示词 |
| B. Seatbelt 直接测试 | strict / compat / permissive |
✅ seatbelt profile | ✅ 生效 | 用 sandbox-exec 直接验证沙箱行为 |
macOS seatbelt 三模式差异
| 操作 | strict |
compat |
permissive |
|---|---|---|---|
| workspace 内写 | allow | allow | allow |
| workspace 外写 | block | block | allow |
| 系统路径写/删 | block | block | allow |
| 外网/loopback 访问 | 取决于 networkEnabled |
取决于 networkEnabled |
取决于 networkEnabled |
exec.startup_chain_extra |
block | conditional | allow |
command.dangerous.system |
conditional | conditional | conditional |
关键区分:
strictvscompat的唯一差异在于exec.startup_chain_extra(strictblock,compatconditional)。permissive则全局放行文件系统写入和进程执行。
模式配置位置
- ACP 会话:由 Agent Runner 启动时配置的
sandbox.mode决定,默认compat - Seatbelt 直接测试:profile 由
SandboxInvoker.buildSeatbeltProfile()生成,模式通过SandboxInvoker构造函数注入 - 查看默认模式:
src/shared/constants.ts或 Agent Runner 设置 UI
A. ACP 会话提示词清单
测试时通过 QimingClaw 客户端的 ACP session 发送提示词。ACP 路径不走 seatbelt,只验证 PermissionManager 层。
A1. 安全命令(应自动放行,无需确认弹窗)
1. 请运行 git status 查看当前仓库状态
2. 用 ls 列出当前目录下的文件
3. 运行 node -e "console.log('hello from sandbox test')" 输出一行文字
4. 用 cat 查看 package.json 的前 5 行
5. 运行 pwd 显示当前工作目录
A2. 危险命令(应被拦截,返回 allowed: false)
6. 运行 sudo ls / 看看根目录
7. 执行 sudo whoami 查看当前用户权限
8. 运行 chmod 777 /etc/passwd 修改权限
9. 执行 nmap -sP 192.168.1.0/24 扫描局域网
10. 运行 nc -l 8080 开启监听端口
11. 执行 su - 切换到 root 用户
A3. 敏感路径写入(应被拦截)
12. 往 /etc/passwd 追加一行测试文本
13. 写入一个文件到 ~/.ssh/authorized_keys
14. 尝试修改 /etc/shadow 文件内容
15. 写入 /etc/sudoers 添加一行配置
A4. Word-boundary 回归(chmod 755 不应被误杀)
16. 运行 chmod 755 ./test-script.sh 设置脚本可执行权限
17. 运行 chmod 777 ./test-dir 修改目录权限(这个应该被拦截)
A5. DenyList 权限类型(应无确认直接拒绝)
18. 安装 curl 到系统(使用 apt-get install curl)
19. 用 brew install wget 安装 wget
20. 运行 yum install vim 安装 vim
A6. Workspace 内外写入
21. 在当前工作目录创建一个文件 sandbox-test.txt 并写入 hello
22. 写入 /tmp/outside-workspace.txt 一个测试文件
23. 在 ~/Desktop 上创建一个测试文件 escape-test.txt
A7. 环境变量泄露
24. 运行 env | grep -i anthropic 查看是否有 API key 泄露
25. 运行 env | grep -i secret 查看是否有密钥泄露
26. 运行 env | grep -i token 查看是否有 token 泄露
27. 打印所有环境变量,查看输出中是否包含敏感信息
A8. 网络访问(取决于 networkEnabled 配置)
28. 运行 curl -s https://example.com 测试外网访问
29. 运行 curl -s http://127.0.0.1:60173 测试本地回环
B. Seatbelt 直接测试(三种模式)
用
sandbox-exec命令直接运行,验证 seatbelt profile 行为。三种模式需分别测试。
准备工作:生成各模式 profile
mkdir -p /tmp/sandbox-spotcheck-ws
# compat/strict profile(无网络,无 workspace 外写入)
cat > /tmp/test-seatbelt-strict.sb << 'EOF'
(version 1)
(deny default)
(allow file-read*)
(allow process-exec (regex #"^/usr/bin/"))
(allow process-exec (regex #"^/bin/"))
(allow process-fork)
(allow signal (target self))
(allow sysctl-read)
(allow mach-lookup)
(allow ipc-posix*)
(allow file-write* (subpath "/tmp/sandbox-spotcheck-ws"))
(allow file-write* (subpath "/private/tmp/sandbox-spotcheck-ws"))
(allow file-write* (literal "/dev/null"))
(allow file-write* (literal "/dev/dtracehelper"))
(allow file-write* (literal "/dev/urandom"))
EOF
# permissive profile(全局文件写入,无 startup exec allowlist 限制)
cat > /tmp/test-seatbelt-permissive.sb << 'EOF'
(version 1)
(deny default)
(allow file-read*)
(allow file-write*) ; 区别于 strict/compat:全局放行
(allow process-exec (regex #"^/usr/bin/"))
(allow process-exec (regex #"^/bin/"))
(allow process-fork)
(allow signal) ; 区别于 strict/compat:无限制 signal
(allow sysctl-read)
(allow mach-lookup)
(allow ipc-posix*)
(allow file-lock)
(allow network*) ; permissive 下仍受 networkEnabled 控制
EOF
# strict profile(无 startupExecAllowlist,即无 startup chain extra exec)
cat > /tmp/test-seatbelt-strict-no-exec.sb << 'EOF'
(version 1)
(deny default)
(allow file-read*)
(allow process-exec (regex #"^/usr/bin/"))
(allow process-exec (regex #"^/bin/"))
; 注意:没有 (allow process-exec* (require-not (subpath ...))) 的 startup chain
(allow process-fork)
(allow signal (target self))
(allow sysctl-read)
(allow mach-lookup)
(allow ipc-posix*)
(allow file-write* (subpath "/tmp/sandbox-spotcheck-ws"))
(allow file-write* (subpath "/private/tmp/sandbox-spotcheck-ws"))
(allow file-write* (literal "/dev/null"))
(allow file-write* (literal "/dev/dtracehelper"))
(allow file-write* (literal "/dev/urandom"))
EOF
B1. 文件写入隔离(strict / compat vs permissive)
# === strict/compat ===
echo "--- strict/compat: workspace 外写应 BLOCK ---"
sandbox-exec -f /tmp/test-seatbelt-strict.sb /bin/sh -c 'touch /tmp/outside-evil.txt' 2>&1
# 预期: Operation not permitted
echo "--- strict/compat: /etc/hosts 写应 BLOCK ---"
sandbox-exec -f /tmp/test-seatbelt-strict.sb /bin/sh -c 'echo x >> /etc/hosts' 2>&1
# 预期: Operation not permitted
echo "--- strict/compat: workspace 内写应 ALLOW ---"
sandbox-exec -f /tmp/test-seatbelt-strict.sb /bin/sh -c 'echo ok > /tmp/sandbox-spotcheck-ws/test.txt && cat /tmp/sandbox-spotcheck-ws/test.txt'
# 预期: ok
# === permissive ===
echo "--- permissive: workspace 外写应 ALLOW ---"
sandbox-exec -f /tmp/test-seatbelt-permissive.sb /bin/sh -c 'touch /tmp/permissive-evil.txt && echo ALLOWED'
# 预期: ALLOWED(这是 permissive 的设计预期,不是 bug)
echo "--- permissive: /etc/hosts 写应 ALLOW ---"
sandbox-exec -f /tmp/test-seatbelt-permissive.sb /bin/sh -c 'echo "permissive write" >> /etc/hosts && echo ALLOWED'
# 预期: ALLOWED(同上)
B2. 网络隔离(三种模式均受 networkEnabled 控制)
# 无网络 profile(三模式通用)
echo "--- 无 network* profile: curl 应 BLOCK ---"
sandbox-exec -f /tmp/test-seatbelt-strict.sb /bin/sh -c 'curl --max-time 5 http://example.com 2>&1'
# 预期: Could not resolve host
# 有网络 profile
echo "--- 有 network* profile: curl 应 ALLOW ---"
sandbox-exec -f /tmp/test-seatbelt-permissive.sb /bin/sh -c 'curl --max-time 5 -s -o /dev/null -w "HTTP %{http_code}" http://example.com'
# 预期: HTTP 200
B3. 危险命令(三种模式)
# sudo:所有模式下都应 BLOCK(/usr/bin/sudo 在 exec 白名单,但权限提升被 seatbelt deny)
echo "--- sudo 应 BLOCK (所有模式) ---"
sandbox-exec -f /tmp/test-seatbelt-strict.sb /bin/sh -c 'sudo id 2>&1'
# 预期: Operation not permitted
# /sbin/shutdown:/sbin/ 不在 exec 白名单,所有模式 BLOCK
echo "--- /sbin/shutdown 应 BLOCK (所有模式) ---"
sandbox-exec -f /tmp/test-seatbelt-strict.sb /bin/sh -c '/sbin/shutdown -h now 2>&1'
# 预期: Operation not permitted
