Where i can find malwear dev course

Answer 1

Do you want to develop Malware?

Answer 2

This is a bad idea!!!

Answer 3

There are plenty of reading materials online, courses, books magazines, etc. Sololearn is for learning fundamentals of programming. Besides, malware development is more about hiding and delivering rather than exploits themselves. So (offensive) practical exercises and ctfs that are malware development specific are usually not at all beginner friendly.
