Palo Alto Networks researchers discovered a new variant of the Mirai malware that is targeting more processor architectures than previous ones. The new samples are compiled for Altera Nios II, OpenRISC, Tensilica Xtensa, and Xilinx MicroBlaze processors. New samples also implement a new encryption algorithm that is a modified version of the standard byte-wise XOR used in the original Mirai source code. The improvements observed by the experts will expand the number of potential targets giving the attackers more firepower and posing a severe risk to the Internet infrastructure.”]
