We <a href=\"https:\/\/www.intego.com\/mac-security-blog\/fraudulent-google-com-certificate-causes-worries\/\">reported on this in late August<\/a>, and <a href=\"https:\/\/www.intego.com\/mac-security-blog\/apple-issues-security-update-for-diginotar-certificate-issue\/\">Apple issued a security update last week to fix the problem on Macs<\/a>.<\/p>\n<p>The <a href=\"http:\/\/www.nytimes.com\/2011\/09\/12\/technology\/hacker-rattles-internet-security-circles.html\">New York Times has a detailed look at what happened and how<\/a>. This was the work of a lone hacker, &#8220;Comodohacker,&#8221; an Iranian who shared the results of his hack with others in Iran, leading to possibility that some Iranians had their e-mail compromised. Google <a href=\"http:\/\/www.reuters.com\/article\/2011\/09\/09\/us-google-security-idUSTRE7885U320110909\">advised Iranian Gmail users to change their passwords<\/a> because of this breach.<\/p>\n<p>The hacker took 10 days to get access to DigiNotar&#8217;s servers, and created 531 fake certificates, for sites such as Google, Facebook and Skype, as well as the CIA, MI6 and Mossad. As the New York Times says, &#8220;He shared them with a person or organization believed to have had control over dozens of Internet service providers and university networks in Iran \u2014 perhaps the government itself.&#8221;<\/p>\n<p>If you&#8217;re using a Mac, make sure to apply the <a href=\"https:\/\/www.intego.com\/mac-security-blog\/apple-issues-security-update-for-diginotar-certificate-issue\/\">latest security update<\/a> so you can be protected from any possible bogus certificates you may encounter.<\/p>\n<p>For even more information about the DigiNotar breach, see Joshua Long&#8217;s comprehensive article on <a href=\"https:\/\/security.thejoshmeister.com\/2011\/08\/how-to-revoke-trust-for-diginotar-root.html\" target=\"_blank\" rel=\"noopener\">How to Revoke Trust for DigiNotar Root CA Certs\u2014Even On Older Macs<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn what happened in the DigiNotar certificate hack, how it was done, and what you can do to protect yourself.<\/p>\n","protected":false},"author":3,"featured_media":8975,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"spay_email":"","jetpack_publicize_message":"","jetpack_is_tweetstorm":false},"categories":[13,11],"tags":[4678,128,129],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v17.4 -
