Overview
General Information
Detection
Score: | 21 |
Range: | 0 - 100 |
Whitelisted: | false |
Signatures
Sample is packed with UPX
ELF contains segments with high entropy indicating compressed/encrypted content
Sample contains only a LOAD segment without any section mappings
Uses the "uname" system call to query kernel version information (possible evasion)
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. |
