Both companies are huge operations with figures of €1.816 billion (A$2.97 billion) revenue for Campari in 2017, and ¥95.4 billion (A$1.26 billion) for Capcom in 2019, according to information available on Wikipedia.
A statement put out by Campari said the attack on its infrastructure took place on 2 November and resulted in the encryption of data on some of its servers. In a notice posted on the dark web, the attackers claimed they had stole 2TB of sensitive data.
The media release also claimed that the company could not "completely exclude that some personal and business data has been taken". This claim was pooh-poohed by the attackers, who said, "This is ridiculous and looks like a big fat lie. We can confirm that confidential data was stolen and we are talking about a huge volume of data."
Capcom has a number of well-known games such as Street Fighter, Resident Evil, Devil May Cry, Monster Hunter, and Mega Man.
The gaming firm said in an announcement that it had also been hit on 2 November and some of its networks had been hit as a result of which access to some systems, including email and file servers, was affected.
It said this was due to "unauthorised access carried out by a third party", adding that it had shut down some operations of internal networks since the time of the breach.
The people behind this attack said they had stolen about 1TB of sensitive data which included personal information of clients and employees, business information, confidential files and non-disclosure agreements.
Capcom was also given time until 10 November to contact the attackers in order to avoid the leaking of the stolen data.
Ragnar Locker has not been used in any big attacks since it was reported to have hit the French transport and logistics firm CMA CGM Group in September.
