IoT Honeypot Traffic Analysis Series. Analysis of Edimax IC-7113W, part 4

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

On February 28th, 2019 we infected one of our devices with the malware sample that most AV detect as Mirai. However, it was a bash script downloader that obtains and exacute an ARM ELF binary to attack others using the HNAP vulnerability in order to infect new bots.

Analysis of an IRC based Botnet

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.
