Once a crypter becomes popular on GitHub, security companies (like Microsoft, CrowdStrike, or Bitdefender) download the source code. Signature Updates:

At the core of a crypter's functionality is the process of encryption and obfuscation. A standard crypter takes a compiled binary—often a Remote Access Trojan (RAT), keylogger, or ransomware—and encrypts its contents. It then attaches a unique "stub," which is a small piece of code responsible for decrypting the original payload directly into the computer's memory at runtime. By ensuring that the malicious code never touches the hard drive in its raw form, crypters successfully bypass traditional static signature-based detection used by antivirus software. When a crypter achieves FUD status, it means it can bypass all major security products on the market at that given time.
