The code checks if it is being run in a virtual machine (common for security researchers) and shuts down if it is.

GitHub, a popular platform for developers to share and collaborate on code, has been associated with various FUD Crypter projects. Some developers claim to share FUD Crypters on GitHub for educational purposes or to aid in penetration testing and red teaming activities. However, these tools can also be exploited for malicious purposes. GitHub, a popular platform for developers to share
The crypter adds "junk code" or renames variables to confuse heuristic scanners that look for suspicious patterns. Injection:
