From a new press release on their website:
As there is an ongoing investigation in place, it is possible that new facts may come to light going forward. Below is a general summary of what has been confirmed at this point in time (as of November 16, 2020).
1. Information verified to have been compromised
i. Personal information: 9 items
ii. Other information
- Personal information of former employees: 5 items
- (Name & signature: 2 items; name & address: 1 item; passport information: 2 items)
- Personal information of employees: 4 items
- (Name and HR information: 3 items; name & signature: 1 item)
2. Potentially compromised data
- Sales reports
- Financial information
i. Personal information (customers, business partners, etc.): maximum of approx. 350,000 items
ii. Personal information (employees and related parties)
- Japan: Customer service video game support help desk information (approx.134,000 items)
- Names, addresses, phone numbers, email addresses
- North America: Capcom Store member information (approx. 14,000 items)
- Names, birthdates, email addresses
- North America: Esports operations website members (approx. 4,000 items)
- Names, email addresses, gender information
- List of shareholders (approx. 40,000 items)
- Names, addresses, shareholder numbers, amount of shareholdings
- Former employees' (including family) information (approx. 28,000 people);
- applicants' information (approx. 125,000 people)
- Names, birthdates, addresses, phone numbers, email addresses, photos, etc.
iii. Confidential corporate information
- Human resources information (approx. 14,000 people)
None of the at-risk data contains credit card information. All online transactions etc. are handled by a third-party service provider, and as such Capcom does not maintain any such information internally.
- Sales data, business partner information, sales documents, development documents, etc.
So names, addresses, and phone numbers. Nothing terribly dangerous, at least in the hands of hackers, but nothing people can easily change. An unfortunate update, but there's not a whole lot to be done about it either.
