Leaked Documents Expose the Secretive Market for Your Web Browsing Data

An antivirus program used by hundreds of millions of people around the world is selling highly sensitive web browsing data to many of the world’s biggest companies, a joint investigation by Motherboard and PCMag has found. Our report relies on leaked user data, contracts, and other company documents that show the sale of this data is both highly sensitive and is in many cases supposed to remain confidential between the company selling the data and the clients purchasing it.

The documents, from a subsidiary of the antivirus giant Avast called Jumpshot, shine new light on the secretive sale and supply chain of peoples’ internet browsing histories. They show that the Avast antivirus program installed on a person’s computer collects data, and that Jumpshot repackages it into various different products that are then sold to many of the largest companies in the world. Some past, present, and potential clients include Google, Yelp, Microsoft, McKinsey, Pepsi, Sephora, Home Depot, Condé Nast, Intuit, and many others. Some clients paid millions of dollars for products that include a so-called “All Clicks Feed,” which can track user behavior, clicks, and movement across websites in highly precise detail.

Avast claims to have more than 435 million active users per month, and Jumpshot says it has data from 100 million devices. Avast collects data from users that opt-in and then provides that to Jumpshot, but multiple Avast users told Motherboard they were not aware Avast sold browsing data, raising questions about how informed that consent is.

The data obtained by Motherboard and PCMag includes Google searches, lookups of locations and GPS coordinates on Google Maps, people visiting companies’ LinkedIn pages, particular YouTube videos, and people visiting porn websites. It is possible to determine from the collected data what date and time the anonymized user visited YouPorn and PornHub, and in some cases what search term they entered into the porn site and which specific video they watched.

Although the data does not include personal information such as users’ names, it still contains a wealth of specific browsing data, and experts say it could be possible to deanonymize certain users.

In a press release from July, Jumpshot claims to be “the only company that unlocks walled garden data” and seeks to “provide marketers with deeper visibility into the entire online customer journey.” Jumpshot has previously discussed some of its clients publicly. But other companies mentioned in Jumpshot documents include Expedia, IBM, Intuit, which makes TurboTax, Loreal, and Home Depot. Employees are instructed not to talk publicly about Jumpshot’s relationships with these companies.

“It’s very granular, and it’s great data for these companies, because it’s down to the device level with a timestamp,” the source said, referring to the specificity and sensitivity of the data being sold. Motherboard granted the source anonymity to speak more candidly about Jumpshot’s processes.

Until recently, Avast was collecting the browsing data of its customers who had installed the company’s browser plugin, which is designed to warn users of suspicious websites. Security researcher and AdBlock Plus creator Wladimir Palant published a blog post in October showing that Avast harvest user data with that plugin. Shortly after, browser makers Mozilla, Opera, and Google removed Avast’s and subsidiary AVG’s extensions from their respective browser extension stores. Avast had previously explained this data collection and sharing in a blog and forum post in 2015. Avast has since stopped sending browsing data collected by these extensions to Jumpshot, Avast said in a statement to Motherboard and PCMag…….Read More>>
