Obfuscated bash script targeting QNap boxes, (Mon, Nov 26th)

One of our readers, Nathaniel Vos, shared an interesting shell script with us and thanks to him! He found it on an embedded Linux device, more precisely, a QNap NAS running QTS 4.3. After some quick investigations, it looked that the script was not brand new. we found references to it already posted in September 2018[1]. But such shell scripts are less common: they are usually not obfuscated and they perform basic features like downloading and installing some binaries. So, I took the time to look at it.
