memory, which is meant to be inaccessible to users, was only theoretically possible.<\/p>\n<p>&#8220;When I saw my private website addresses from Firefox being dumped by the tool I wrote, I was really shocked,&#8221; Gruss told Reuters in an email interview, describing how he had unlocked personal data that should be secured.<br \/>\nGruss, Lipp and Schwarz, working from their homes on a weekend in early December, messaged each other furiously to verify the result.<\/p>\n<p>&#8220;We sat for hours in disbelief until we eliminated any possibility that this result was wrong,&#8221; said Gruss, whose mind kept racing even after powering down his computer, so he barely caught a wink of sleep.<\/p>\n<p>Gruss and his colleagues had just confirmed the existence of what he regards as &#8220;one of the worst CPU bugs ever found&#8221;.<\/p>\n<p><strong>The flaw, now named Meltdown, was revealed on Wednesday and affects most processors manufactured by Intel since 1995.<\/strong><\/p>\n<p>Separately, a second defect called Spectre has been found that also exposes core memory in most computers and mobile devices running on chips made by Intel, Advanced Micro Devices and ARM Holdings, a unit of Japan&#8217;s Softbank.<\/p>\n<p>&#8230;click on the above link to read the rest of the article&#8230;<\/p>\n<\/div>\n<\/div>\n<\/article>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The &#8220;Meltdown&#8221;
