Signatures
Antivirus / Scanner detection for submitted sample
Multi AV Scanner detection for submitted file
Sample is packed with UPX
Sample contains only a LOAD segment without any section mappings
Yara signature match
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)
Classification
Analysis Advice |
---|
Static ELF header machine description suggests that the sample might only run correctly on MIPS or ARM architectures |
All HTTP servers contacted by the sample do not answer. Likely the sample is 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 not execute correctly on this machine |
