To put it bluntly, a single credential resulted in the exfiltration of potentially hundreds of companies that stored their data using Snowflake, with the threat actor himself suggesting 400 companies are impacted. The goal of the threat actor, as in most cases, was to blackmail Snowflake into buying their own data back for $20,000,000.

Santander, a major financial organization, had been breached, and all customer data was offered for sale: the price was $2 million.

Uh huh. A bank. So probably a lot of companies with important stuff.

Ah, they have a "customer" section that lists some customers with 202 entries.

Albertsons looks like the first.

Pfizer. Sainsbury's. PlayStation. AT&T. Euintelsat OneWeb (that's the sorta-kinda Starlink competitor). NHS Greater Manchester Integrated Care Partnership. Freddie Mac (large US government-backed mortgage lender). Capital One, a bank. Anthem, a major health insurer. A bunch of California government institutions. NatWest, a bank. Western Union. Vimeo. Siemens. Comcast. Cedar Health, a company that provides healthcare billing services. Aflac, an insurance company.

Yup, sounds like this isn't good.

Well, I've said before that it'd probably take some kind of really catastrophic computer security event for things to change.
