A collection of new Mirai malware samples compiled to run on new processors and architectures have been discovered by Palo Alto Networks’ Unit 42 in the wild during late February 2019. The samples are compiled for Altera Nios II, OpenRISC, Tensilica Xtensa, and Xilinx MicroBlaze processors. The new samples also came with a number of exploits also found in previous Mirai samples, ranging from a ThinkPHP Remote Code Execution exploit and a D-Link DSL2750B OS Command Injection.
