The U.S. is pushing the message that the world should address ransomware collectively.

The talks leave out the nation President Biden most often criticizes, but invitees will meet for two days on countering ransomware.

The burger chain, which reported $19.2 billion revenue last year, becomes the latest fast food vendor to have customer data stolen by hackers.

The suspect allegedly made some $10,500 from ransomware attacks.

Three groups targeted seven prominent companies in Canada, France, India, South Korea and the United States, Microsoft said.

ESET is hoping publicizing the malware will shake loose clues in their hunt for the enigmatic hackers.
