I'm excited to share with you a video collaboration with @herrcore from OALabs about unpacking a self-injection malware. Definitely also checkout their channel if you want to learn more about malware analysis!
OALabs shows a walk-through of how to unpack a sample malware and explains some basics about packers. You can learn about using x64debug, IDA and PE-Bear.
