Quote: According to researchers Alexandre Mundo, John Fokker and Thomas Roccia from cybersecurity firm McAfee, GandCrab, perhaps due to its cult status in underground forums, has managed to team up with a crypter service. In a blog post, the researchers said that "the speed of change is impressive and increases the difficulty of combating it."

Crypters are often a key component of obfuscation. Rather than change the signature of malware itself, obfuscation aims to use different delivery methods to circumvent antivirus protections.
