Signatures
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Yara detected Mirai
Sample is packed with UPX
ELF contains segments with high entropy indicating compressed/encrypted content
Executes the "rm" command used to delete files or directories
Sample contains only a LOAD segment without any section mappings
Uses the "uname" system call to query kernel version information (possible evasion)
Yara signature match
Classification
Analysis Advice
Static ELF header machine description suggests that the sample might not execute correctly on this machine. |
Exit code information suggests that the sample terminated abnormally, try to lookup the sample's target architecture. |
Non-zero exit code suggests an error during the execution. Lookup the error code for hints. |
Static ELF header machine description suggests that the sample might only run correctly on MIPS or ARM architectures. |

Mirai | Mirai is one of the first significant botnets targeting exposed networking devices running Linux. Found in August 2016 by MalwareMustDie, its name means "future" in Japanese. Nowadays it targets a wide range of networked embedded devices such as IP cameras, home routers (many vendors involved), and other IoT devices. Since the source code was published on "Hack Forums" many variants of the Mirai family appeared, infecting mostly home networks all around the world. | No Attribution |
