In this blog post we introduce the “Hexa Payload Decoder Tool”, a tool that is able to process a pcap file and return any decoded characters translated to English. This tool was developed to assist the network security analyst when working and interpreting data sent and received by command and control servers used by malware.
We presented a talk at the Packet Hacking Village in Defcon titled "Beyond Sandboxes. How to Execute IoT Malware and Analyze its evolution. We showed how we designed and deployed an IoT malware execution laboratory to run malware for months and how we analyzed it to find novel attacks.
In this IoT Honeypot Analysis Series, we focus on the traffic analysis of the Edimax IC-7113W camera. In this episode, we will continue with the analysis of the encrypted packets mentioned in the previous episode. Our goals for this blog post are:
to obtain the AES key from the Edimax server
to understand what happens with the communication after we obtain the AES key
to get a plaintext of the encrypted payload sent from the camera to the server
This blog post describes the analysis of a malware sample that was executed in a RapsberryPi from our IoT laboratory. The SHA256 of the sample that we executed in our laboratory is: d8040a64b88b4a738d333015ddd93a27187abb7584412df56633a7e7d12127f4.
This blogpost aims to give an insight of an IRCBased botnet describing the network behavior and showing the analysis of the C&C. By analyzing this botnet network traffic it was possible to identify the botmasters using an IRC channel and observe not only the conversation between them but also the orders they give to the bot.
