# Performing Automated Malware Analysis with Cape


## Genel Bakış

CAPE (Config And Payload Extraction) is an open-source malware sandbox derived from Cuckoo that automates behavioral analysis, payload dumping, and configuration extraction. CAPEv2 features API hooking for behavioral instrumentation, captures files created/modified/deleted during execution, records network traffic in PCAP format, and includes 70+ custom configuration extractors (cape-parsers) for families like Emotet, TrickBot, Cobalt Strike, AsyncRAT, and Rhadamanthys. The signature system includes 1000+ behavioral signatures Tespit etme evasion techniques, persistence, credential theft, and ransomware behavior. CAPE's debugger enables dynamic anti-evasion bypasses combining debugger actions within YARA signatures. Recommended Dağıt:ment: Ubuntu LTS host with Windows 10 21H2 guest VM.

## İş Akışı

### Adım 1: Submit and Analyze Samples via API

```python
#!/usr/bin/env python3
"""CAPE sandbox API client for automated malware submission and analysis."""
