Or none of this is news to you. We&#8217;ll see.<\/p>\n<p>According to the research, an Apple iPhone that goes asleep into low-power mode or is turned off isn&#8217;t necessarily protected against surveillance. That&#8217;s because some parts of it are still operating at low power.<\/p>\n<div aria-hidden=\"true\" class=\"adun\" data-pos=\"top\" data-raptor=\"condor\" data-xsm=\",fluid,mpu,\" data-sm=\",fluid,mpu,\" data-md=\",fluid,mpu,\"> <noscript> <a href=\"https:\/\/pubads.g.doubleclick.net\/gampad\/jump?co=1&amp;iu=\/6978\/reg_security\/research&amp;sz=300x50%7C300x100%7C300x250%7C300x251%7C300x252%7C300x600%7C300x601&amp;tile=2&amp;c=2YoXkhhc4O7FpyJQIh460gQAAANY&amp;t=ct%3Dns%26unitnum%3D2%26raptor%3Dcondor%26pos%3Dtop%26test%3D0\" target=\"_blank\" rel=\"noopener\"> <img decoding=\"async\" src=\"https:\/\/pubads.g.doubleclick.net\/gampad\/ad?co=1&amp;iu=\/6978\/reg_security\/research&amp;sz=300x50%7C300x100%7C300x250%7C300x251%7C300x252%7C300x600%7C300x601&amp;tile=2&amp;c=2YoXkhhc4O7FpyJQIh460gQAAANY&amp;t=ct%3Dns%26unitnum%3D2%26raptor%3Dcondor%26pos%3Dtop%26test%3D0\" alt> <\/a> <\/noscript> <\/div>\n<p>Under iOS 15, some chips inside an iPhone in either of those two power states remain active so that the owner can always wirelessly locate their lost cellphones via the Find My iPhone functionality, open their nearby locked cars, or make payments.

Design of LPM features seems to be mostly driven by functionality, without considering threats outside of the intended applications.&#8221;<\/p>\n<h3 class=\"crosshead\"> <span>Don&#8217;t panic<\/span><br \/>\n<\/h3>\n<p>There are some significant caveats to this. The biggest one is that in order to infect the LPM firmware, so that malicious code can continue running even when the phone is seemingly asleep or off, the device needs to be completely compromised. Whoever has this necessary level of control over your phone can already snoop on your messages, steal your data, change your apps, and so on. Modifying the firmware is the cherry on the cake for whoever has infiltrated your device; it&#8217;s an unnecessary step against the vast majority of victims, and only necessary for some truly high-level targets.<\/p>\n<p>That said, it appears that once you have this privileged access, there are no protections in the device to stop you changing the LPM firmware.<\/p>\n<p>&#8220;On modern iPhones, wireless chips can no longer be trusted to be turned off after shutdown,&#8221; the SeeMoo academics wrote. &#8220;This poses a new threat model.&#8221;<\/p>\n<h3 class=\"crosshead\"> <span>It takes a switch<\/span><br \/>\n<\/h3>\n<p>The researchers said they responsibly disclosed these findings to Apple engineers before the paper was publicly distributed. However, the team said they received no feedback from Apple. The academics recommend Apple add a hardware-based switch to disconnect the battery to improve security and protect valuable surveillance targets such as scientists, activists, politicians, and journalists.<\/p>\n<p>Some countries secretly installed NSO Group&#8217;s <a target=\"_blank\" href=\"https:\/\/www.theregister.com\/2022\/04\/18\/uk_catalan_spyware\/\" rel=\"noopener\">controversial<\/a> Pegasus spyware on smartphones to covertly and remotely track people, including reporters, campaigners, and other citizens. It&#8217;s perhaps this level of snoopware that would take advantage of the lack of protections around LPM firmware.<\/p>\n<p>Jaye Tillison, director of security strategy at Axis Security, told <i>The Register<\/i> SeeMoo&#8217;s research is important though the threat right now is muted: it&#8217;s non-trivial to fully exploit.<\/p>\n<div aria-hidden=\"true\" class=\"adun\" id=\"story_eagle_xsm_sm_md_xmd_lg_xlg\" data-pos=\"mid\" data-raptor=\"eagle\" data-xsm=\",mpu,dmpu,\" data-sm=\",mpu,dmpu,\" data-md=\",mpu,dmpu,\" data-xmd=\",mpu,dmpu,\" data-lg=\",mpu,dmpu,\" data-xlg=\",mpu,dmpu,\"> <noscript> <a href=\"https:\/\/pubads.g.doubleclick.net\/gampad\/jump?co=1&amp;iu=\/6978\/reg_security\/research&amp;sz=300x50%7C300x100%7C300x250%7C300x251%7C300x252%7C300x600%7C300x601&amp;tile=3&amp;c=33YoXkhhc4O7FpyJQIh460gQAAANY&amp;t=ct%3Dns%26unitnum%3D3%26raptor%3Deagle%26pos%3Dmid%26test%3D0\" target=\"_blank\" rel=\"noopener\"> <img decoding=\"async\" src=\"https:\/\/pubads.g.doubleclick.net\/gampad\/ad?co=1&amp;iu=\/6978\/reg_security\/research&amp;sz=300x50%7C300x100%7C300x250%7C300x251%7C300x252%7C300x600%7C300x601&amp;tile=3&amp;c=33YoXkhhc4O7FpyJQIh460gQAAANY&amp;t=ct%3Dns%26unitnum%3D3%26raptor%3Deagle%26pos%3Dmid%26test%3D0\" alt> <\/a> <\/noscript> <\/div>\n<p>That said, &#8220;if threat actors begin targeting iOS devices with new malware this could have a huge impact on businesses, and their attack surface \u2013 which has now expanded to every user device and across all working locations \u2013 both in and out of the office,&#8221; Tillison said.<\/p>\n<p>&#8220;We typically see a significant percentage of end-users connecting through an iOS device. If you think about the 300 million users just within the Fortune 2000 accounts alone, with 2.5 end user devices per user, that number can be huge.&#8221;<\/p>\n<p>It&#8217;s also a warning as businesses continue to use more of these technologies: &#8220;Security must become embedded into the fabric of IoT [Internet of Things],&#8221; he said. &#8220;For far too long, we&#8217;ve coasted and coasted along.&nbsp;We&#8217;ve ignored security due to cost. This is not a good road to keep traveling down.&#8221;<\/p>\n<p>Enterprises need to adopt technologies that don&#8217;t allow infected devices to connect to the corporate network, and equipment that inspects traffic \u2013 even private traffic \u2013 to keep sensitive data from flowing down to compromised devices, and to realize that employees need to be educated to protect themselves, he said. \u00ae<\/p>\n<p> READ MORE <a href=\"https:\/\/go.theregister.com\/feed\/www.theregister.com\/2022\/05\/19\/apple-iphone-malware\/\">HERE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>No, you&#8217;re not really gonna be hacked.
