👉 Fraud fluid refers to a sophisticated and adaptive type of malware designed to evade detection by traditional security measures, often used in advanced persistent threats (APTs). It operates by dynamically altering its code and behavior to blend in with legitimate software, making it extremely difficult for antivirus programs and intrusion detection systems to identify. This fluidity is achieved through techniques like code obfuscation, polymorphism, and encryption, allowing the malware to remain undetected while continuously adapting to new environments and defenses. Consequently, fraud fluid poses a significant challenge for cybersecurity professionals, requiring advanced threat detection and response strategies that can keep pace with its evolving tactics.
