Royal [offline]
Royal initially used third-party ransomware including BlackCat and Zeon before developing its own malware, written in C++, which infects Windows systems.
As is typical of most ransomware operations, BlackSuit targets a range of industries with a geographical bias towards those located in the United States. It’s highest-profile attack to date is thought to be against CDK Global, a Software-as-a-Service provider for car dealerships.
BlackSuit was seized in July 2025, in a US-led law enforcement operation that recovered over $1 million of virtual currency.
