7 Variants (So Far) of Mirai

Mirai is an example of the newest trend in rapidly evolving, constantly improving malware. These seven variants show how threat actors are making bad malware worse.

Okiru
Unlike Satori, Okiru - based, in part, on Satori's improvements to Mirai - is broad in its scope. Okiru targets systems with an Argonaut RISK Core (ARC) processor and uses executable and linkable format (ELF) distribution files.
The ARC target is important because ARC processors are used in a vast number of IoT devices. In addition, ELF files are commonly used as a distribution source for Linux applications; using them for Okiru brings into reach IoT devices running a Linux variant as the embedded OS.
Some researchers consider Okiru, first identified in January 2018, to be a version of Satori. But the advances in target architecture and distribution method show the kind of evolution that gives Okiru a name of its own.

Beat the robots
It's scary to think that there are more than people trying to introduce hazards and dangers into our systems you know. These bots are so easily configured to attack from a different angle just by switching up a line or two of code! Security teams are really going to have to work hard to stay ahead of the game now!

Under control
Malware, like technology, is constantly improving. There really isn't any particular one way that can totally diminish this entire threat for good. However, it is still in our best interests that we take note of them so as to know what to expect and how to handle and take them down for good using the correct methods. If we find out about them without knowing the counter measures to be put in place, then we might suffer even tougher consequences that might just be irreversible.
