Manufacturer Bricks Smart Vacuum After Engineer Blocks It From Collecting Data

Slashdot.org - 39 min 19 sec ago

A curious engineer discovered that his iLife A11 smart vacuum was remotely "killed" after he blocked it from sending data to the manufacturer's servers. By reverse-engineering it with custom hardware and Python scripts, he managed to revive the device to run fully offline. Tom's Hardware reports: An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device. 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. After a lengthy investigation, he discovered that a remote kill command had been issued to his device. 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. After several rounds of back-and-forth, the service center probably got tired and just stopped accepting it, saying it was out of warranty. Because of this, he decided to disassemble the thing to determine what killed it and to see if he could get it working again. [...] So, why did the A11 work at the service center but refuse to run in his home? The technicians would reset the firmware on the smart vacuum, thus removing the kill code, and then connect it to an open network, making it run normally. But once it connected again to the network that had its telemetry servers blocked, it was bricked remotely because it couldn't communicate with the manufacturer's servers. Since he blocked the appliance's data collection capabilities, its maker decided to just kill it altogether. "Someone -- or something -- had remotely issued a kill command," says Harishankar. "Whether it was intentional punishment or automated enforcement of 'compliance,' the result was the same: a consumer device had turned on its owner." In the end, the owner was able to run his vacuum fully locally without manufacturer control after all the tweaks he made. This helped him retake control of his data and make use of his $300 software-bricked smart device on his own terms. As for the rest of us who don't have the technical knowledge and time to follow his accomplishments, his advice is to "Never use your primary WiFi network for IoT devices" and to "Treat them as strangers in your home."

China Delays Shenzhou-20 Crew Return After Suspected Space Debris Impact

Slashdot.org - 3 hours 39 min ago

China has delayed the return of its Shenzhou-20 crewed spacecraft after it was suspected to have been struck by space debris while docked at the Tiangong space station. "The Shenzhou-20 crewed spacecraft is suspected of being struck by a small piece of space debris, and impact analysis and risk assessment are underway," the China Manned Space Engineering Office (CMSEO) statement Nov. 5 read. "To ensure the safety and health of the astronauts and the complete success of the mission, it has been decided that the Shenzhou-20 return mission, originally scheduled for Nov. 5, will be postponed." SpaceNews reports: CMSEO did not specify the location of the suspected strike, the extent of any damage, or the data that indicated an impact. No potential dates were noted for a return to Earth. The Shenzhou-20 spacecraft launched April 24, carrying three astronauts -- commander Chen Dong and crewmates Chen Zhongrui and Wang Jie -- to the Tiangong space station. The spacecraft docked at the radial port of Tiangong's Tianhe core module. The crew have completed their six-month-long mission in orbit, and had handed over control of the space station to the newly-arrived Shenzhou-21 crew Nov. 4. Checks on the Shenzhou-20 spacecraft could include telemetry and leak tests, verifying guidance and propulsion systems, and screening for impacts in accelerometer and acoustic sensor data. A key concern would be potential damage to the spacecraft's thermal protection system or parachute deployment structures, both critical for safe atmospheric reentry and landing. Tiangong features a 10-meter-long robotic arm, capable of crawling, and a smaller, more precise arm. These could be employed to position cameras and provide closeup imagery of a potential impact. Crews may be able to conduct an extravehicular activity (EVA) to assess the situation. Tiangong crews have recently added debris shields during a number of EVAs; the same procedures, tools, and arm support can be adapted for a Shenzhou inspection.

Universe Expansion May Be Slowing, Not Accelerating, Study Suggests

Slashdot.org - 6 hours 39 min ago

A new study challenges the Nobel-winning theory that the universe's expansion is accelerating, suggesting instead that it may be slowing down as dark energy weakens -- potentially leading to a future "big crunch" where the cosmos collapses back in on itself. "Our study shows that the universe has already entered a phase of decelerated expansion at the present epoch and that dark energy evolves with time much more rapidly than previously thought," said Prof Young-Wook Lee, of Yonsei University in South Korea, who led the work. "If these results are confirmed, it would mark a major paradigm shift in cosmology since the discovery of dark energy 27 years ago." The Guardian reports: The latest work focuses on the reliability of observations of distant supernovae (exploding stars) that led to the discovery of dark energy, work that was awarded the 2011 Nobel prize in physics. [...] By estimating the ages of 300 host galaxies using a different method, the team concluded that there are simply variations in the properties of stars in the early universe that mean they produce, on average, fainter supernovae. Correcting for this systematic bias still results in an expanding universe, but suggests that the expansion has slowed down and that dark energy is waning, the analysis concluded. If dark energy keeps decreasing to the point where it becomes negative, the universe is theoretically predicted to end in a big crunch. The findings are published in Monthly Notices of the Royal Astronomical Society.
