What are three factors that can be used in domain generation algorithms? (Choose three.)

The correct answer is A. cryptographic keys B. time of day C. other unique values. Domain Generation Algorithms (DGAs) are used by malware to programmatically generate large sets of pseudo-random domain names for C2 communication, making blocklists ineffective. DGAs are seeded with values such as cryptographic keys (A), the current time of day or date (B), and

Explanation

Domain Generation Algorithms (DGAs) are used by malware to programmatically generate large sets of pseudo-random domain names for C2 communication, making blocklists ineffective. DGAs are seeded with values such as cryptographic keys (A), the current time of day or date (B), and other unique values like hardware identifiers (C). URL custom categories (D) are a firewall classification concept unrelated to DGA seed inputs. IP addresses (E) are network identifiers, not typical DGA seed material.
