Nowadays, there are approximately 200 announced sandbox detection methods. Sandboxes, especially analyzing in the Hypervisor layer, are immune to these detection methods. But sandboxes aren't so good at user interaction yet. You can get an advantage by using Pickl3 in your developed malware. For example, end users are generally targeted in today's Red Team operations. The end users targeted have a password, and as long as the user you are targeting does not enter their password correctly, you can prevent your malware from working and bypass the possible sandbox control. However, it would be good if you prevent your malware from working with Administrator rights during the first installation. Because, in sandboxes, malwares are generally analyzed in Administrator rights.
