Unit 42 researchers have taken a closer look at four Mirai variants from two recently discovered campaigns leveraging command injection vulnerability exploits that reveal a familiar IoT attack pattern. A total of four Mirai variants were recently discovered. Two new vulnerabilities were leveraged as attack vectors to deliver Mirai. Upon successful exploitation, the wget utility is invoked to download a shell script from the malware infrastructure. The shell script then downloads several Mirai binaries compiled for different architectures and executes these downloaded binaries one by one.
