Malware To Reverse Engineer

Hi

I’m relatively new to reverse engineering and would like to get more experience by researching/examining a specific piece of malware, preferably something in Linux. I was wondering if anyone has recommendations for known malware that a beginner could hopefully understand by purely reverse engineering? I assume theZoo repository contains at least one item someone at my level could successfully reverse engineer, but there’s a lot to choose from and I’m unsure where to start. Any advice would be greatly appreciated!
