UBER’S SECRET TOOL FOR KEEPING THE COPS IN THE DARK. “At least two dozen times, the San Francisco headquarters locked down equipment in foreign offices to shield files from police raids:”

Most tech companies don’t expect police to regularly raid their offices, but Uber isn’t most companies. The ride-hailing startup’s reputation for flouting local labor laws and taxi rules has made it a favorite target for law enforcement agencies around the world. That’s where this remote system, called Ripley, comes in. From spring 2015 until late 2016, Uber routinely used Ripley to thwart police raids in foreign countries, say three people with knowledge of the system. Allusions to its nature can be found in a smattering of court filings, but its details, scope, and origin haven’t been previously reported.

The Uber HQ team overseeing Ripley could remotely change passwords and otherwise lock up data on company-owned smartphones, laptops, and desktops as well as shut down the devices. This routine was initially called the unexpected visitor protocol. Employees aware of its existence eventually took to calling it Ripley, after Sigourney Weaver’s flamethrower-wielding hero in the Alien movies. The nickname was inspired by a Ripley line in Aliens, after the acid-blooded extraterrestrials easily best a squad of ground troops. “Nuke the entire site from orbit. It’s the only way to be sure.”

Other companies have shut off computers during police raids, then granted officers access after reviewing a warrant. And Uber has reason to be cautious with the sensitive information it holds about customers and their locations around the world. Ripley stands out partly because it was used regularly—at least two dozen times, the people with knowledge of the system say—and partly because some employees involved say they felt the program slowed investigations that were legally sound in the local offices’ jurisdictions.

I’ll defer to Glenn’s legal judgement, but at least in some cases Ripley looks an awful lot like obstruction of justice.
