 #Take a UPX compressed binary & try reading Sections
 > file "soar.upx" && readelf -S "soar.upx"
  soar.upx: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), statically linked, no section header
  There are no sections in this file.

 #Add a dummy section to a UPX Compressed Binary
 > add-section -i "soar.upx" -o "/tmp/soar"
  Original ELF info:
    Input file: /tmp/tmp.lFIkq70PBI/soar.upx
    Architecture: 64-bit x86_64
