On GitHub, you will find hundreds of repositories dedicated to these tools. They typically work by wrapping a malicious payload (the "stub") inside a layer of encryption. When the file is executed, the crypter decrypts the payload directly into the computer's memory (RAM), avoiding the need to write the suspicious file to the hard drive where most AV scanners look. Common Features Found in GitHub Repositories
