  • Not really. They used to have pretty good privacy agreements. I don’t know about now. They do supply agrigate information to pharmaceutical companies, but that has become a pretty fungible resource. The only big consumer of individual DNA information is law enforcement, and that’s more of an expense than an income flow, since reviewing warrants and providing responses costs money.

    An important lesson in infosec is that the best way to reduce the cost of discovery and warrant compliance is to regularly delete any data you don’t need or aren’t legally required to retain. Companies like this don’t have that option. Data is both an asset and a liability.




  • A little searching finds only one company that really fits the bill. Costco has a market cap of $433B and had a reported $14.8B cash on hand as of May 11. That’s an interesting possibility that I wouldn’t have guessed. Costco is less evil than most big corporations, so that’s a little hopeful if I got it right.

    Oracle comes close with a market cap of $583B. That’s indeed over $400B, but that would make the description a bit weird. In any case, Oracle makes more sense from a business angle. Unfortunately, they are near the top of the evil scale.



  • Those are IPv6 addresses that work a bit differently than IPv4. Most customers only get assigned a single IPv4 address, and even a lot of big data centers only have one or two blocks of 256 addresses. The smallest allocation of IPv6 for a single residential customer is typically a contiguous block of the 18,446,744,073,709,551,616 addresses mentioned.

    If Google’s security team is even marginally competent, they will recognize those contiguous blocks and treat them as they would a single IPv4 address. Every address in that block has the same prefix, and it’s actually easier to track on those prefixes than on the entire address.
