Anyone looking into RE, I’d highly suggest `Practical Malware Analysis` by Michael Sikorski. You can find this book on Amazon here! I was also able to obtain a copy from Humble Bundle when the they had a security offering. I’d highly suggest checking them out too, great company doing greater things.
This book has good info on setting up your env safely and working the labs provided which you can find here: https://practicalmalwareanalysis.com/labs/
**KEEP IN MIND THE FOLLOWING**
The lab binaries contain malicious code and you should not install or run these programs without first setting up a safe environment.
