Obfuscation in Cyber Security: Techniques Explained - SentinelOne

Onyx Crypter (often found as onxyCrypter.rar or Onyx Crypter.exe ) is designed to take an existing executable and wrap it in a layer of encryption. When the resulting file is run, a "stub" decrypts the original payload into the computer's memory to execute it without ever saving the unencrypted malicious file to the hard drive. Core Technical Features onxyCrypter.rar

: Supports "RunPE" techniques, which involve starting a legitimate system process (like explorer.exe ) and injecting the malicious code into its memory space. : Features to detect if it is running

: Features to detect if it is running in a Virtual Machine (VM) or sandbox environment (e.g., Any.Run or AnyRun) and terminate if so. Potential Risks & Associations junk code insertion

: Uses techniques like variable renaming, junk code insertion, and control flow flattening to confuse reverse engineers.

Based on common distributions and source code analysis of versions like those found on GitHub , this crypter typically includes:

: The primary intent is to achieve a 0/X detection rate on scanners like VirusTotal.
