The Security Risks of Third-Party Data

Most of us get to be thoroughly relieved that our e-mails weren't in the Ashley Madison database. But don't get too comfortable. Whatever secrets you have, even the ones you don't think of as secret, are more likely than you think to get dumped on the Internet. It's not your fault, and there's largely nothing you can do about it.

Welcome to the age of organizational doxing.

Organizational doxing -- stealing data from an organization's network and indiscriminately dumping it all on the Internet -- is an increasingly popular attack against organizations. Because our data is connected to the Internet, and stored in corporate networks, we are all in the potential blast-radius of these attacks. While the risk that any particular bit of data gets published is low, we have to start thinking about what could happen if a larger-scale breach affects us or the people we care about. It's going to get a lot uglier before security improves.

We don't know why anonymous hackers broke into the networks of Avid Life Media, then stole and published 37 million -- so far -- personal records of AshleyMadison.com users. The hackers say it was because of the company's deceptive practices. They expressed indifference to the "cheating dirtbags" who had signed up for the site. The primary target, the hackers said, was the company itself. That philanderers were exposed, marriages were ruined, and people were driven to suicide was apparently a side effect.

Last November, the North Korean government stole and published gigabytes of corporate e-mail from Sony Pictures. This was part of a much larger doxing -- a hack aimed at punishing the company for making a movie parodying the North Korean leader Kim Jong-un. The press focused on Sony's corporate executives, who had sniped at celebrities and made racist jokes about President Obama. But also buried in those e-mails were loves, losses, confidences, and private conversations of thousands of innocent employees. The press didn't bother with those e-mails -- and we know nothing of any personal tragedies that resulted from their friends' searches. They, too, were caught in the blast radius of the larger attack.

The Internet is more than a way for us to get information or connect with our friends. It has become a place for us to store our personal information. Our e-mail is in the cloud. So are our address books and calendars, whether we use Google, Apple, Microsoft, or someone else. We store to-do lists on Remember the Milk and keep our jottings on Evernote. Fitbit and Jawbone store our fitness data. Flickr, Facebook, and iCloud are the repositories for our personal photos. Facebook and Twitter store many of our intimate conversations.

It often feels like everyone is collecting our personal information. Smartphone apps collect our location data. Google can draw a surprisingly intimate portrait of what we're thinking about from our Internet searches. Dating sites (even those less titillating than Ashley Madison), medical-information sites, and travel sites all have detailed portraits of who we are and where we go. Retailers save records of our purchases, and those databases are stored on the Internet. Data brokers have detailed dossiers that can include all of this and more.

Many people don't think about the security implications of this information existing in the first place. They might be aware that it's mined for advertising and other marketing purposes. They might even know that the government can get its hands on such data, with different levels of ease depending on the country. But it doesn't generally occur to people that their personal information might be available to anyone who wants to look.

In reality, all these networks are vulnerable to organizational doxing. Most aren't any more secure than Ashley Madison or Sony were. We could wake up one morning and find detailed information about our Uber rides, our Amazon purchases, our subscriptions to pornographic websites -- anything we do on the Internet -- published and available. It's not likely, but it's certainly possible.

Right now, you can search the Ashley Madison database for any e
