Malware based on domain generation algorithms often utilizes factors that can be programmatically generated and are unique or predictable. Time of day can be a consistent input for generating unique domain names at different intervals. Other unique values may include values like system information or random seeds that the algorithm uses to ensure the generated domain names are not easily identifiable by pattern. Cryptographic keys can be used to encrypt parts of the domain generation process, making the output harder to replicate without the keys. These factors support the creation of dynamically changing domains to evade detection by security systems.
