Explanation
Ransomware encrypts victim files and renames them with new extensions (e.g., .locked, .encrypted), causing a sudden spike in file extension changes and rename operations - exactly the behavior described. DoS attacks (B) flood a target with traffic to cause service disruption and have no effect on the filesystem. DHCP starvation (C) exhausts a DHCP server's IP address pool, affecting network connectivity, not files. File injection (D) inserts malicious content into existing files but does not mass-rename or re-extend them.
Memory tip: Think "RansomWARE = file changes everywhere" - the ransom demand comes after the attacker has already scrambled your files, which is why rapid bulk renaming is the telltale sign to watch for in endpoint monitoring.
