So You Want To Be A Malware Analyst - Malwarebytes Labs | Malwarebytes Labs[^]

In order for a Malware Analyst to be able to read the malware code, they will need to disassemble it. Unfortunately, the highest language derived from binary code is Assembly, which is the last level of human readable code. Therefore, it is imperative that a would-be Malware Analyst, also learn how to read and write Assembly code.
