🤖 Agent 使用说明

1. 用户提到"分析 X 日志 / 取证 / 检测威胁 / 渗透测试 / 安全审计"时触发对应 skill

2. skill 按操作步骤执行(取证镜像 / 解析日志 / 跑威胁情报)

3. 涉及破坏性操作前必须 ask user 确认

4. 完工后跑自检

5. 区分"防御性分析" vs "恶意代码审计"

👤 用户需要做什么?

1. 告诉 Agent 你要做什么(分析日志 / 取证 / 安全审计 / 渗透测试)

2. 按 Agent 提示提供文件/镜像/日志/哈希

3. 涉及破坏性操作时明确告诉 Agent"继续"或"取消"

4. 全程 Agent 自动化,你只需提供数据 + 回答决策点

name: analyzing-malware-sandbox-evasion-techniques

description: Detect sandbox and VM evasion techniques in malware samples by analyzing

timing checks, VM/hypervisor artifact queries, user-interaction checks, and sleep-inflation

patterns from Cuckoo or AnyRun behavioral reports. Use when a sample shows no or

minimal activity in a sandbox, when a behavioral report needs review for evasion

indicators, or when building detections for anti-analysis techniques.

Analyzing Malware Sandbox Evasion Techniques

Overview

Sandbox evasion (MITRE ATT&CK T1497) allows malware to detect analysis environments and alter behavior to avoid detection. This skill analyzes behavioral reports from Cuckoo Sandbox and AnyRun for evasion indicators including timing-based checks (GetTickCount, QueryPerformanceCounter, sleep inflation), VM artifact detection (registry keys, MAC address prefixes, process names like vmtoolsd.exe), user interaction checks (mouse movement, keyboard input), and environment fingerprinting (disk size, CPU count, RAM). Detection rules flag samples exhibiting these behaviors for deeper manual analysis.

When to Use

• When investigating security incidents that require analyzing malware sandbox evasion techniques
• When building detection rules or threat hunting queries for this domain
• When SOC analysts need structured procedures for this analysis type
• When validating security monitoring coverage for related attack techniques

Prerequisites

• Cuckoo Sandbox 2.0+ or AnyRun account for behavioral analysis reports
• Python 3.8+ with json library for report parsing
• Behavioral report exports in JSON format

Steps

1. Parse Cuckoo/AnyRun behavioral report JSON files

2. Extract API call sequences for timing-related functions

3. Identify VM artifact detection via registry queries and WMI calls

4. Detect sleep inflation by comparing requested vs actual sleep durations

5. Flag user interaction checks (GetCursorPos, GetAsyncKeyState patterns)

6. Score evasion sophistication based on technique count and diversity

7. Map detected techniques to MITRE ATT&CK T1497 sub-techniques

Expected Output

JSON report listing detected evasion techniques with MITRE ATT&CK mapping, API call evidence, evasion sophistication score, and classification of evasion categories (timing, VM detection, user interaction, environment fingerprinting).
