Dynamic Malware Analysis

This is a malware analysis project which expecte to generate snort rule via malicious network traffic

Requirement package

• pyvbox: for creating an sandbox.
• dpkt: for parsering network packet.
• requests: for sending requests to VirusTotal

Isolation environment in VirtualBox

1. Take the snapshot (manually)
2. Copy the malware into virtual machine
3. Active the malware
4. Record the network traffic (Save in the host) in the virtual machinei
5. Restore the snapshot (Which means goto step 0)

Usage

• Isolation environment usage

  Show help messages

$ python sandbox_run.py -h

usage: sandbox_run.py [-h] [-n NAME] [-t TIME] [-m MALWARE]

This is a automatic script which record malware network behavior in the
isolation environment.

optional arguments:
  -h, --help            show this help message and exit
  -n NAME, --name NAME  Specify a VM name.
  -t TIME, --time TIME  Specify a time in seconds for recording network
                        traffic.
  -m MALWARE, --malware MALWARE
                        Specify a path which place malware will be copy into
                        sandbox.

The following example is starting a virtual machine named WinXPSP3 and capturing network traffic for 60 seconds.

$ python sandbox_run.py -n WinXPSP3 -t 60 -m malware_bin

• Packet reconstruct Usage

  Show help message

$ python pkt_reconstruct.py -h

usage: pkt_reconstruct.py [-h] [-d DIRECTORY]

This is a packet reconstruct tool to help reconstruct the packet payload.

optional arguments:
  -h, --help            show this help message and exit
  -d DIRECTORY, --directory DIRECTORY
                        Specify a path which place pcap file

Todo

1. Analysis malicious network traffic from packet reconstruct
2. Automatic generate the snort rule depending on analyse results
3. A Web GUI interface for user can upload the malware and generate snort rule
