Laser hack of self-driving cars can ‘delete’ pedestrians

<p>Although a city filled with entirely self-driving cars is still in the realm of science fiction, more and more cars are <a href="https://en.wikipedia.org/wiki/Tesla_Autopilot" target="_blank" rel="noopener">coming with ‘self-driving’ features so</a> it’s a little alarming to learn that there are ways to use lasers to mess with the technology the cars use to detect its surroundings.</p> <p><a href="https://arxiv.org/abs/2210.09482" target="_blank" rel="noopener">In a study uploaded to arXiv</a> by a team of researchers in the US and Japan, researchers were able to trick the ‘victim vehicle’ (their words not ours) into not seeing a pedestrian or other object in its way.</p> <p>Most self-driving cars use LIDAR to be able to ‘see’ around them by sending out a laser light and then recording the reflection from objects in the area. The time it takes for the light to reflect back gives the system information about how far away the object is.</p> <p>This new ‘hack’ or spoof works because a perfectly timed laser shined onto a LIDAR system can create a blind spot large enough to hide an object like a pedestrian.</p> <p>“We mimic the LIDAR reflections with our laser to make the sensor discount other reflections that are coming in from genuine obstacles,” <a href="https://www.eurekalert.org/news-releases/969698" target="_blank" rel="noopener">said University of Florida cyber security researcher professor Sara Rampazzi.</a></p> <p>“The LIDAR is still receiving genuine data from the obstacle, but the data are automatically discarded because our fake reflections are the only one perceived by the sensor.”</p> <div class="newsletter-box"> <div id="wpcf7-f6-p221287-o1" class="wpcf7" dir="ltr" lang="en-US" role="form"> </div> </div> <p>Although the technology is relatively simple, the attack isn’t an easy one. The team demonstrated the attack up to 10 meters away from the car, but the device must be perfectly timed, and move with the car to be able to keep the laser pointing the right way.</p> <p>The researchers have already told manufacturers about this potential exploit and have suggested ways to be able to minimise the problem. Manufacturers might be able to teach the software to look for the tell-tale signatures of the spoofed reflections added by the laser attack.</p> <p>“Revealing this liability allows us to build a more reliable system,” <a href="https://www.eurekalert.org/news-releases/969698" target="_blank" rel="noopener">said first author, University of Michigan computer scientist Yulong Cao.</a></p> <p>“In our paper, we demonstrate that previous defence strategies aren’t enough, and we propose modifications that should address this weakness.”</p> <p>This unfortunately isn’t the first time that researchers have found <a href="https://cosmosmagazine.com/news/tricking-driverless-car-sensors/" target="_blank" rel="noreferrer noopener">vulnerabilities with LIDAR sensors on self-driving cars</a>, but as more of these problems are uncovered and fixed, the technology will hopefully end up safer in the long run.</p> <p>The research is to be presented next year at the <a href="https://www.usenix.org/conference/usenixsecurity23" target="_blank" rel="noopener">2023 USENIX Security Symposium</a>.</p> <p><img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=221287&amp;title=Laser+hack+of+self-driving+cars+can+%E2%80%98delete%E2%80%99+pedestrians" width="1" height="1" /></p> <div id="contributors"> <p><em><a href="https://cosmosmagazine.com/technology/laser-hack-lidar-self-driving-cars-delete-pedestrians/" target="_blank" rel="noopener">This article</a> was originally published on Cosmos Magazine and was written by Jacinta Bowler.</em></p> <p><em>Image: Getty Images</em></p> </div>

Kirstie Alley slammed over deleted Ukraine tweet

<p>Ballroom dancing champion and former Dancing With the Stars contestant Maksim Chmerkovskiy, who’s been posting live updates from inside war-torn Ukraine, has called out Kirstie Alley for tweeting that she doesn’t know what’s “real” and “fake” about Russia invading his home country.</p> <p>Maksim Chmerkovskiy, who’s been posting live updates from Ukraine has called out Kirstie Alley for tweeting she doesn’t know what’s “real” and “fake” about Russia invading his home country.</p> <p>“I don’t know what’s real or what is fake in this war. So I won’t be commenting. I’ll pray instead,” Alley wrote in a since-deleted tweet.</p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/02/New-Project-3.jpg" alt="" width="585" height="503" /></p> <p>Chmerkovskiy then posted a screenshot of the tweet, writing, “Dear Kirstie, We haven’t spoken in a while, but I clearly remember being right next to you while you were organising trucks of aid during hurricane Sandy and I remember all that you were saying to me about situations where innocent are suffering.”</p> <p>“That same energy is needed right now.”</p> <p>He added, “No one needs your prayer if you don’t know what’s real or fake.”</p> <p>The US Dancing With the Stars alum has been in Kyiv, the capital of Ukraine, as Russia’s attacks on the country continue.</p> <p style="box-sizing: inherit; margin: 0px 0px 5px; padding: 0px; border: 0px; font-size: 16px; vertical-align: baseline; color: #323338; font-family: Roboto, Arial; background-color: #ffffff; outline: none !important;">“I’m safe,” he assured fans on Friday. “We haven’t been told to move, and I’m just following instructions.

Emotional deleted scene from Mrs Doubtfire

<p>In 2014, the world was rocked by the sudden death of Robin Williams, but newly surfaced alternate scenes from his much beloved comedy <em>Mrs Doubtfire</em> showcase what a loss his incredible acting talents really were.</p> <p>The two deleted scenes in this video show a much darker and more dramatic side to the film that what inevitably made it to the final cut. Both scenes show Williams’ character Daniel and his wife Sally (played by Sally Field) fighting in front of their kids. The second scene is shot from the children’s point of view, and it’s absolutely gut-wrenching – especially since it was reportedly set to play just after Sally discovers Mrs. Doubtfire’s true identity.</p> <p>I don’t know about you, but I’m glad they stuck with the final cut.</p> <p><strong>Related links:</strong></p> <p><a href="/entertainment/movies/2016/03/original-ending-of-pretty-woman-was-shockingly-different/"><strong><em><span style="text-decoration: underline;">The original ending of Pretty Woman was shockingly different</span></em></strong></a></p> <p><a href="/entertainment/movies/2016/02/best-family-movies/"><strong><em><span style="text-decoration: underline;">Top 10 movies to watch with the whole family</span></em></strong></a></p> <p><a href="/entertainment/movies/2015/12/sound-of-music-cast-then-and-now/"><strong><em><span style="text-decoration: underline;">What the cast of The Sound of Music are doing now</span></em></strong></a></p>

Newly surfaced deleted scenes of Mrs Doubtfire will break your heart

<p>The classic family comedy <em>Mrs Doubtfire</em> has warmed hearts since it landed on screens back in 1993. For years Robin Williams has delighted kids and adults with his antics as the titular housekeeper in the light-hearted and charming film.</p> <p>But now newly surfaced deleted scenes show the film could have been a lot sadder. Even heartbreaking.</p> <p>One scene shows Williams’ daughter in spelling bee before being distracted by her parents arguing in the crowd. In an emotional talk, she asks her dad why he can’t be Mrs Doubtfire again.</p> <p>“Life’s more real and wonderful than [acting all day],” Williams says. “Acting... it’s nice but it’s a job.”</p> <p>In another heartbreaking scene, Williams and Field are shown in a brutal argument after Fields’ realises Williams is Mrs Doubtfire. The children are upstairs listening to every word.</p> <p>While the film will always be remembered for the comic genius of Robin Williams, and the classic moments will always remain hilarious, it shows just how close the movie was to becoming a story of divorce and family heartache. </p> <p><strong>Related links: </strong></p> <p><span style="text-decoration: underline;"><strong><em><a href="http://www.oversixty.co.nz/entertainment/movies/2015/12/top-10-horror-movies/">Top 10 classic horror movies of all-time</a></em></strong></span></p> <p><span style="text-decoration: underline;"><strong><em><a href="http://www.oversixty.co.nz/entertainment/movies/2015/11/best-kids-movies/">10 of the best movies to watch with the grandkids</a></em></strong></span></p> <p><span style="text-decoration: underline;"><strong><em><a href="http://www.oversixty.co.nz/entertainment/movies/2015/11/sean-connery-is-the-best-james-bond/">5 reasons why Sean Connery is our favourite Bond</a></em></strong></span></p>
