Malware Analysis Techniques - Undercode Testing

In today’s digital world, it is critical to understand the structure and operation of malware in order to deal with rapidly evolving new threats. Malware analysis helps us minimize the impact of these threats and make our systems more secure. Our goal is to create a safer digital environment by uncovering hidden threats.

Useful Commands and Tools for Malware Analysis

1. Static Analysis:

Use `strings` to extract human-readable strings from a binary:
```
strings malware_sample.exe 
```

Analyze PE headers with pefile:

pip install pefile 
pefile malware_sample.exe

2. Dynamic Analysis:

Monitor system calls with `strace` on Linux:
```
strace -f ./malware_sample 
```
Use `Process Monitor` (ProcMon) on Windows to track file, registry, and network activity.

3. Sandboxing:

Run malware in a controlled environment using Cuckoo Sandbox:
```
cuckoo submit malware_sample.exe 
```

4. Network Analysis:

Capture network traffic with tcpdump:

tcpdump -i eth0 -w malware_traffic.pcap

Analyze traffic with Wireshark:
```
wireshark malware_traffic.pcap 
```

5. Memory Analysis:

Dump memory with Volatility:
```
volatility -f memory_dump.img pslist 
```

What Undercode Say

Malware analysis is a critical skill in cybersecurity, enabling professionals to dissect and understand malicious software. By combining static and dynamic analysis techniques, analysts can uncover the behavior, purpose, and origin of malware. Tools like strings, strace, Cuckoo Sandbox, and `Volatility` are indispensable for this process. On Windows, tools like `Process Monitor` and `Wireshark` provide deep insights into malware activity.

For those new to malware analysis, starting with basic tools and gradually moving to advanced techniques is recommended. Practice analyzing sample malware in a safe, isolated environment to build expertise. Additionally, understanding assembly language and reverse engineering can significantly enhance your analysis capabilities.
