I am in possession of a jar file that I have reason to believe has a RAT inside. I downloaded it inside of a virtual machine with jad installed and began to attempt to look at the source. I found that jad was useful for decompiling one file at a time, but I didn't see any obvious way to decompile folders of .class files at a time.
Is jad the best tool for this, or is there a better tool? I'm on a debian 32 bit system. Could you also tell me the best command to use if it is jad?
In doing research on this question, I saw this outdated question, and also this outdated question, but I want a more up to date solution.

JAD has been unmaintained for a while now. For decompiling a jar, I typically use JD-GUI, just as your linked question proposes.
