Vulnerability in Amazon Key

Amazon Key is an IoT door lock that can enable one-time access codes for delivery people. To further secure that system, Amazon sells Cloud Cam, a camera that watches the door to ensure that delivery people don’t abuse their one-time access privilege.

Cloud Cam has been hacked:

But now security researchers have demonstrated that with a simple program run from any computer in Wi-Fi range, that camera can be not only disabled but frozen. A viewer watching its live or recorded stream sees only a closed door, even as their actual door is opened and someone slips inside. That attack would potentially enable rogue delivery people to stealthily steal from Amazon customers, or otherwise invade their inner sanctum.

And while the threat of a camera-hacking courier seems an unlikely way for your house to be burgled, the researchers argue it potentially strips away a key safeguard in Amazon’s security system.

Amazon is patching the system.

Turning an Amazon Echo into an Eavesdropping Device

For once, the real story isn’t as bad as it seems. A researcher has figured out how to install malware onto an Echo that causes it to stream audio back to a remote controller, but:

The technique requires gaining physical access to the target Echo, and it works only on devices sold before 2017. But there’s no software fix for older units, Barnes warns, and the attack can be performed without leaving any sign of hardware intrusion.

The way to implement this attack is by intercepting the Echo before it arrives at the target location. But if you can do that, there are a lot of other things you can do. So while this is a vulnerability that needs to be fixed — and seems to have inadvertently been fixed — it’s not a cause for alarm.

Amazon Patents Measures to Prevent In-Store Comparison Shopping

Amazon has been issued a patent on security measures that prevents people from comparison shopping while in the store. It’s not a particularly sophisticated patent — it basically detects when you’re using the in-store Wi-Fi to visit a competitor’s site and then blocks access — but it is an indication of how retail has changed in recent years.

What’s interesting is that Amazon is on the other of this arms race. As an on-line retailer, it wants people to walk into stores and then comparison shop on its site. Yes, I know it’s buying Whole Foods, but it’s still predominantly an online retailer. Maybe it patented this to prevent stores from implementing the technology.

It’s probably not nearly that strategic. It’s hard to build a business strategy around a security measure that can be defeated with cellular access.

Law Enforcement Access to IoT Data

In the first of what will undoubtedly be a large number of battles between companies that make IoT devices and the police, Amazon is refusing to comply with a warrant demanding data on what its Echo device heard at a crime scene.

The particulars of the case are weird. Amazon’s Echo does not constantly record; it only listens for its name. So it’s unclear that there is any evidence to be turned over. But this general issue isn’t going away. We are all under ubiquitous surveillance, but it is surveillance by the companies that control the Internet-connected devices in our lives. The rules by which police and intelligence agencies get access to that data will come under increasing pressure for change.
