Their weight inefficiency is not of big concern in cars.</li></ul>Likewise I'm confident we see first <a href="https://infosec.space/tags/LiFePO4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiFePO4</a> then <a href="https://infosec.space/tags/SodiumWetcells" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SodiumWetcells</a> then <a href="https://infosec.space/tags/FuelCells" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FuelCells</a> take over.<ul><li>On the flipside, I hope we'll see more <a href="https://infosec.space/tags/BatterySwap" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BatterySwap</a> systems that'll use standardized <a href="https://infosec.space/tags/LiFePO4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiFePO4</a> cells (maybe not a giant stack of 21700's on cars, but on <a href="https://infosec.space/tags/eBikes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#eBikes</a> and maybe 14500's <a href="https://infosec.space/tags/MobileDevices" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MobileDevices</a>) which could solve the <a href="https://infosec.space/tags/charging" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#charging</a> speed problem.</li></ul>In fact I'm confident <a href="https://infosec.space/tags/MethanolFuelcell" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MethanolFuelcell</a> will be used as drop-in replacement for (diesel-)<a href="https://www.youtube.com/watch?v=AqHsXv7Umvw" rel="nofollow noopener noreferrer" target="_blank">electric buses</a> simply because of scalability and <a href="https://www.youtube.com/watch?v=B78-FgNqdc8" rel="nofollow noopener noreferrer" target="_blank">fire safety</a> alone.<ul><li>OFC the superior solution for regular bus lines are <a href="https://www.youtube.com/watch?v=SB9EARKvCTc" rel="nofollow noopener noreferrer" target="_blank">trolley buses</a>, but being able to refuel on long-distance trips will certainly help conversion with long-haul bus services and <a href="https://infosec.space/tags/trucking" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#trucking</a> beyond the "last-mile stop & go" delivery where drivers have their 8hr shifts and trucks can "slow-charge" at the depot at night.</li></ul>In fact, <a href="https://infosec.space/tags/DeutschePost" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DeutschePost</a> literally bought up an <a href="https://infosec.space/tags/electric" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#electric</a> <a href="https://infosec.space/tags/MiniTrick" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MiniTrick</a> <a href="https://infosec.space/tags/startup" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#startup</a> just to get the "<a href="https://infosec.space/tags/CityScooter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CityScooter</a>" <a href="https://infosec.space/tags/BEV" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BEV</a>|s made for them, and for couriers that only do stop & go these work fine.

Kevin Karhan :verified:<a href="https://mastodon.social/@CStamp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@CStamp</a> <a href="https://mastodon.social/@persagen" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@persagen</a> whilst it's easy to attribute <a href="https://infosec.space/tags/Unit8200" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Unit8200</a> for that, I'd say this is a too easy kind of explaination as it would be in the best interest if the <a href="https://infosec.space/tags/IDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IDF</a> to keep enemies like <a href="https://infosec.space/tags/Hezbollah" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Hezbollah</a> in blissful ignorance about their <a href="https://infosec.space/tags/vulnerable" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#vulnerable</a> <a href="https://infosec.space/tags/tech" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#tech</a> whilst maximizing <a href="https://infosec.space/tags/SIGINT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SIGINT</a> effectiveness by not giving them a reason to implement secure <a href="https://infosec.space/tags/comms" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#comms</a>.To me that sounds like a project some recruit of that unit would've to plan as a means to qualify for membership of that unit.<ul><li>It doesn't make sense to pull that <a href="https://infosec.space/tags/PagerHack" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PagerHack</a> off given it's quite newly deployed (older batteries would've more reliably and faster gone critical due to <a href="https://infosec.space/tags/Overdischarge" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Overdischarge</a>!) and having pulled this <a href="https://infosec.space/tags/exploit" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#exploit</a> also means Hezbollah will clearly fix those issues, starting with devices using <a href="https://infosec.space/tags/NiCd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NiCd</a> or <a href="https://infosec.space/tags/LiFePO4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiFePO4</a> batteries if not employing proper <a href="https://infosec.space/tags/E2EE" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#E2EE</a> instead of using insecure & <a href="https://infosec.space/tags/unencrypted" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#unencrypted</a> <a href="https://infosec.space/tags/POCSAG" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#POCSAG</a>... </li></ul>But since I'm not getting paid for fixing that shitshow AND don't work with or for terrorists (!!!) I won't plug any projects that would've prevented this...

Kevin Karhan :verified:<a href="https://infosec.exchange/@malwaretech" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@malwaretech</a> Yeah, some people really are such unbearable cringelords...<ul><li>That being said, depending on the model in detail and how shitty quality the cells are (after all, pagers don't draw much power so they use like the cheapest rechargeable Li-Ion/LiPo cells) simply making it's SoC / microcontroller overdraw current and not kick in undervoltage protection is a interesting move...</li><li>Certainly this attack would.not have been possinle with <a href="https://infosec.space/tags/LiFePO4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiFePO4</a>, <a href="https://infosec.space/tags/NiCd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NiCd</a> or other regular cells - even cheap zinc-carbon batteries would not blow up when basically shorted...</li></ul>

Kevin Karhan :verified:<a href="https://chaos.social/@Nfoonf" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@Nfoonf</a> wird schon passieren, allein weil <a href="https://infosec.space/tags/Lithium" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lithium</a>-Batterien ne Fehlentwicklung sind und die schnell zu <a href="https://infosec.space/tags/DangerPillow" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DangerPillow</a>|s werden welche dann mit Flussäurehaltigen Dämpfen exotherm durchgehen...<ul><li>IMHO ist es nur ne Frage der Zeit bis <a href="https://infosec.space/tags/LiIon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiIon</a> / <a href="https://infosec.space/tags/LiCo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiCo</a> & <a href="https://infosec.space/tags/LiPo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiPo</a> - Akkus wie verbleites Benzin verboten oder wie <a href="https://infosec.space/tags/NiCd" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NiCd</a> (als <a href="https://infosec.space/tags/LiFePO4" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LiFePO4</a>) nur noch in Spezialanwendungen erlaubt werden!</li></ul>
