Manufacturer Remotely Bricks Smart Vacuum After Its Owner Blocked It From Collecting Data (tomshardware.com) 123

Posted by EditorDavid from the sucking-dirt-and-data dept.
"An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device," writes Tom's Hardware.

"That's when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn't consented to." The user, Harishankar, decided to block the telemetry servers' IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after... He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again... [H]e decided to disassemble the thing to determine what killed it and to see if he could get it working again...

[He discovered] a GD32F103 microcontroller to manage its plethora of sensors, including Lidar, gyroscopes, and encoders. He created PCB connectors and wrote Python scripts to control them with a computer, presumably to test each piece individually and identify what went wrong. From there, he built a Raspberry Pi joystick to manually drive the vacuum, proving that there was nothing wrong with the hardware. From this, he looked at its software and operating system, and that's where he discovered the dark truth: his smart vacuum was a security nightmare and a black hole for his personal data.

First of all, it's Android Debug Bridge, which gives him full root access to the vacuum, wasn't protected by any kind of password or encryption. The manufacturer added a makeshift security protocol by omitting a crucial file, which caused it to disconnect soon after booting, but Harishankar easily bypassed it. He then discovered that it used Google Cartographer to build a live 3D map of his home. This isn't unusual, by far. After all, it's a smart vacuum, and it needs that data to navigate around his home. However, the concerning thing is that it was sending off all this data to the manufacturer's server. It makes sense for the device to send this data to the manufacturer, as its onboard SoC is nowhere near powerful enough to process all that data. However, it seems that iLife did not clear this with its customers.

Furthermore, the engineer made one disturbing discovery — deep in the logs of his non-functioning smart vacuum, he found a command with a timestamp that matched exactly the time the gadget stopped working. This was clearly a kill command, and after he reversed it and rebooted the appliance, it roared back to life.

New Large Coral Reef Discovered Off Naples Containing Rare Ancient Corals (independent.co.uk) 13

Posted by EditorDavid from the reefer-gladness dept.
Off the southwest cost of Italy, a remotely operated submarine made "a significant and rare discovery," reports the Independent — a vast white coral reef that was 80 metres tall (262 feet) and 2 metres wide (6.56 feet) "containing important species and fossil traces." Often dubbed the "rainforests of the sea", coral reefs are of immense scientific interest due to their status as some of the planet's richest marine ecosystems, harbouring millions of species. They play a crucial role in sustaining marine life but are currently under considerable threat...

hese impressive formations are composed of deep-water hard corals, commonly referred to as "white corals" because of their lack of colour, specifically identified as Lophelia pertusa and Madrepora oculata species. The reef also contains black corals, solitary corals, sponges, and other ecologically important species, as well as fossil traces of oysters and ancient corals, the Italian Research Council said. It called them "true geological testimonies of a distant past."

Mission leader Giorgio Castellan said the finding was "exceptional for Italian seas: bioconstructions of this kind, and of such magnitude, had never been observed in the Dohrn Canyon, and are rarely seen elsewhere in our Mediterranean". The discovery will help scientists understand the ecological role of deep coral habitats and their distribution, especially in the context of conservation and restoration efforts, he added.
The undersea research was funded by the EU.
