, these projects are often shared for educational purposes, "red teaming" (ethical hacking), or malware analysis. However, they exist in a legal and ethical gray area because they are also the primary tools used by cybercriminals to distribute ransomware and trojans.

Modern EDRs scan memory for known malicious payloads after decryption. This defeats many in-memory execution techniques. This defeats many in-memory execution techniques

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.
