Following infiltration, .loptr encrypts various data using AES-1024 and RSA-2048 cryptographies. This variant also renames encrypted files using the "[8_random_characters]-[4_random_characters]-[4_random_characters]-[8_random_characters]-[12_random_characters].loptr" pattern (for example, "sample.jpg" might be renamed to something similar to "KGA04L3O-GKM4-LG84-10LPHKJ4-MNTLFO49FL04.loptr").
