A popular smartwatch designed exclusively for children contains an undocumented backdoor that makes it possible for someone to remotely capture camera snapshots, wiretap voice calls, and track locations in real time, a researcher said.

The X4 smartwatch is marketed by Xplora, a Norway-based seller of children’s watches. The device, which sells for about $200, runs on Android and offers a range of capabilities, including the ability to make and receive voice calls to parent-approved numbers and to send an SOS broadcast that alerts emergency contacts to the location of the watch. A separate app that runs on the smartphones of parents allows them to control how the watches are used and receive warnings when a child has strayed beyond a present geographic boundary.

But that’s not all

It turns out that the X4 contains something else: a backdoor that went undiscovered until some impressive digital sleuthing. The backdoor is activated by sending an encrypted text message. Harrison Sand, a researcher at Norwegian security company Mnemonic, said that commands exist for surreptitiously reporting the watch’s real-time location, taking a snapshot and sending it to an Xplora server, and making a phone call that transmits all sounds within earshot.

We're 10 months into 2020, and businesses are still making adjustments to the new realities of large-scale telework (which, if you're not in the IT biz, is just a fancy term for "working from not in the office"). In the Before Times, telework was an interesting idea that tech companies were just starting to seriously flirt with as a normal way of doing business—whereas now, most businesses large or small have a hefty fraction of their workforce staying home to work.

Unfortunately, making such a sweeping change to office workflow doesn't just disrupt policies and expectations—it requires important changes to the technical infrastructure as well. Six months ago, we talked about the changes the people who work from home frequently need to make to accommodate telework; today, we're going to look at the ongoing changes the businesses themselves need to make.

We’re going to need a bigger boat pipe

The most obvious problem that businesses have faced—and are continuing to face—with a greatly multiplied number of remote workers is the size of the company's Internet connection. If you need a quarter—or half, or three quarters—of your workforce to remote in to work every day, you need enough bandwidth to accommodate them.
