In line with one malware researcher on the time, the hackers additionally left behind a requirement for $11 million in Bitcoin in trade for the encryption key.
In its closing report on the matter, launched at the moment, Capcom denied that any particular ransom demand had been made, and mentioned that it was by no means really in touch with the hackers.
The report features a timeline of occasions, from the preliminary detection of potential issues to now, and a slight discount within the variety of particular person accounts confirmed as compromised: 15,640, somewhat than the 16,415 reported in January.

The excellent news, so far as it goes, is that not one of the compromised knowledge included bank card data, and the assault didn’t affect any elements of Capcom’s methods associated to buying or taking part in video games. “It stays protected for Capcom clients or others to connect with the web to play or buy the corporate’s video games on-line,” Capcom mentioned.
Curiously, it additionally clarified that it was by no means really in touch with the attackers, and had not acquired the reported $11 million ransom demand.
“Whereas it’s true that the menace actor behind this assault left a message file on the gadgets that had been contaminated with ransomware containing directions to contact the menace actor to barter, there was no point out of a ransom quantity on this file,” it wrote. “As defined in earlier bulletins, Capcom consulted with legislation enforcement and decided to not interact the menace actor in negotiations; the Firm actually took no steps to make contact … and as such Capcom isn’t conscious of any ransom demand quantities.”
