The hacker also attempts to sell the database for 0.05 bitcoins or $1,300 and the web shell access for 0.25 bitcoins or approximately $6,500. In a similar post on a hacker’s forum, the threat actor said it has access to multiple Twitter accounts that Koei Tecmo has.

“There are FTP credentials on the shell I found and I would be happy to share those with you if you bought the shell as well as multiple Twitter secrets for their Twitter accounts that they have,” said the hacker.

However, three days following the post, the same threat actor has published and leaked a database for free on the same forum. This database contains user members’ names, email addresses, IP addresses, hashed passwords, date of births, and country of residence.

Koei Tecmo clarified that the leaked information didn’t include any financial details as these aren’t stored in the website database. Furthermore, the company said the breach only affected the forum and not other parts of its website.

No further demands were made to the Japanese company, but Koei Tecmo said users can take precautions. Out of caution, the company also cut off the UK subsidiary from its internal network and prevent further damage.

While this news cause worries for users, Koei Tecmo is determined to launch the 20th anniversary series of Fatal Frame. The company is yet to announce some titles in Spring 2021.

A wide range of titles is also expected to come out in 2021, as announced by Fatal Frame producer Keisuke Kikuchi. “I’d like to look at what’s important and what I love once more, and create a game with a fresh perspective,” added Kikuchi.
