While doing heap research on Linux processes (results are going to be published soon), I came across the bot from the Mirai Botnet. As already mentioned in the blog post by Brian, the Mirai bot uses obfuscated configuration data which contains e.g. the CnC server. When now confronted only with a bot (e.g. in the context of a running task or the ELF binary), but without the according source code, the decryption of this configuration data for e.g. incident analysis purposes might not be easily possible (with the python script from the blog post), if the key has been changed.
But in this case that is not a problem at all, because Continue reading “A short Addendum on the Mirai Botnet Blog Post”

A Quick Insight Into the Mirai Botnet
As you might have read, I recently had a closer look at how easy it actually is to become part of an IoT Botnet. To start a further discussion and share some of my findings I gave a quick overview at the recent Dayton Security Summit. The Mirai Botnet was supposed to be one of the case studies here. But the way things go if one starts diving into code…I eventually gave an overview of how the Mirai Bot actually works and what it does. As such: Here a quick summary of the Mirai Botnet bot.
