Which tools and software do we need?

 We will need some software when applying the dynamic analysis method. Let's take a look at these software categories. Virtualization Software We do not want to conduct dynamic analysis on our own system as we need to run the malware to be able to examine its activities. For this reason, we should make use of Virtualization Software that helps us work on some virtual systems. Thanks to these software, you can use a different operating system on your host operating system. If they are configured properly, you can perform your analysis safely, as malicious software cannot escape from this virtual operating system. It is useful to make a small note here on these virtualization software. Since these virtualization environments are essentially software, various vulnerabilities that allow malwares to escape out of these virtual environments and allow code executions on the host operating system may occur on these environments. For this reason, It is crucial to keep your virtualization so...

Packet drafting for IDS_IPS

 Table of contents Introduction Scapy-Overview Snort-Rule References Introduction In this article will demonstrate how we can generate packet that can test/trigger rule in Snort or Suricata using Scapy. Scapy is a packet manipulation tool for computer networks, originally written in Python by Philippe Biondi. It can forge or decode packets, send them on the wire, capture them, and match requests and replies. It can also handle tasks like scanning, tracerouting, probing, unit tests, attacks, and network discovery. Scapy Overview To run Scapy write scapy in your linux terminal as following: ┌──(kali㉿kali)-[~] └─$ sudo scapy [sudo] password for kali:                                                              aSPY//YASa                     apyyyyCY//////////YCa  ...
