Signatures
Yara detected Mirai
Multi AV Scanner detection for submitted file
Yara signature match
Sample has stripped symbol table
Uses the "uname" system call to query kernel version information (possible evasion)
Tries to connect to HTTP servers, but all servers are down (expired dropper behavior)
Sample contains strings indicative of BusyBox which embeds multiple Unix commands in a single executable
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. |
All HTTP servers contacted by the sample do not answer. The sample is likely an old dropper which does no longer work. |
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. |
