Royal
Royal is ransomware that first appeared in early 2022; a version that also targets ESXi servers was later observed in February 2023. Royal employs partial encryption and multiple threads to evade detection and speed encryption. Royal has been used in attacks against multiple industries worldwide--including critical infrastructure. Security researchers have identified similarities in the encryption routines and TTPs used in Royal and Conti attacks and noted a possible connection between their operators.(Citation: Microsoft Royal ransomware November 2022)(Citation: Cybereason Royal December 2022)(Citation: Kroll Royal Deep Dive February 2023)(Citation: Trend Micro Royal Linux ESXi February 2023)(Citation: CISA Royal AA23-061A March 2023)
