Capcom revealed that the recent ransomware attack has potentially impacted 390,000 people, an increase of approximately 40,000 people from the previous report.

In November, Japanese game developer Capcom admitted to have suffered a cyberattack that is impacting business operations.

The company has developed multiple multi-million-selling game franchises, including Street Fighter, Mega Man, Darkstalkers, Resident Evil, Devil May Cry, Onimusha, Dino Crisis, Dead Rising, Sengoku Basara, Ghosts ‘n Goblins, Monster Hunter, Breath of Fire, and Ace Attorney as well as games based on Disney animated properties.

At the time, the Notice Regarding Network Issues published by the company revealed that on the morning of November 2nd, 2020 is suffered a cyberattack, In response to the incident the game developer shut down portions of their corporate network to prevent the malware from spreading.

The incident has not impacted connections for its players, the company initially declared that had not found any evidence that customer data was stolen.

In Mid-November, the company confirmed that the attackers accessed the personal information of its employees, along with financial and business information. The company believes that other information potentially accessed includes sales reports, financial information, game development documents, other information related to business partners.

No credit card information was compromised in the security breach.

After the attack, the Ragnar Locker ransomware operators claimed to have stolen over 1TB of data from the company.

In an update published by the Ragnar ransomware gang on it leak site the operators leaked a collection of archives as proof of the hack.Greetings !

“Unfortunately even such worldwide leading company as CAPCOM doesn’t values much privacy and security. They was notified about vulnerability and data leak numerous time.” reads the post published by Ragnar gang on its leak site. They checked our page with proofs but even this didn’t help them to make a right decision and save data from leakage. Also we would help them to decrypt and also provide with recommendations on security measures improvement, to avoid such issues in future.” reads the post published by the ransomware on its leak site.

“We are sure that everyone should know about CAPCOM’s decision and careless attitude regarding data privacy. This might seems crazy in 21st century, all corporates should work harder on their security measures, especially IT and online based companies.”
