Chammae appears to be a prototype of \u201cBidulgi,\u201d an existing piece of bypass software.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Daily NK previously reported that some North Koreans are using a program that defeats the surveillance and tracking systems used by the North Korean authorities to block smartphone users from accessing foreign information and videos.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Mun Chong Hyun, the head of the ESTsecurity Security Response Center (ESRC), told Daily NK on Monday that Chammae \u201cappeared to be an early version of Bidulgi,\u201d and that the program \u201cconverts outside [non-North Korean] files on a mobile phone.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The copy of Chammae obtained through ESRC ran right away on Windows 7 and 10. No special installation process was required.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Chammae\u2019s icon is striking in that it shows something penetrating a smartphone\u2019s shield. The icon seems to express in direct terms that the program bypasses smartphone security authentications.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On Chammae\u2019s left side panel are options for \u201cmobile phone\u201d and \u201ctablet computer\u201d along with a text field to enter an International Mobile Equipment Identity (IMEI) number, while on the right side is a space to upload the file to convert. Click on \u201ctablet computer,\u201d and the IMEI field changes to \u201cdevice number.\u201d Lacking IMEI numbers as they are not mobile devices, tablet computers appear to use serial numbers for authentication.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The program is relatively easy to use. Select the type of device you would like to stick the file on, enter the IMEI number, add the file to convert to the list, and click \u201cconvert.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Chammae can convert image, document and music files. It cannot convert unpermitted file formats such as Android application packages (APK).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The converted files ran normally after they were copied to a North Korean smartphone. North Korean smartphones automatically delete unauthenticated files. In short, Chammae renders powerless the security systems installed on smartphones by the North Korean authorities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Generally, smartphones available in South Korea and internationally run external files through an internal authentication process. North Korea\u2019s smartphones, however, are designed to run only files authenticated by the authorities.<\/span><\/p>\n<figure id=\"attachment_47112\" aria-describedby=\"caption-attachment-47112\" style=\"width: 300px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-47112\" src=\"https:\/\/www.dailynk.com\/english\/wp-content\/uploads\/sites\/2\/2020\/12\/\ucc38\ub9e4_\ud654\uba74-300x200.jpg\" alt=\"\" width=\"300\" height=\"200\" srcset=\"https:\/\/www.dailynk.com\/english\/wp-content\/uploads\/sites\/2\/2020\/12\/\ucc38\ub9e4_\ud654\uba74-300x200.jpg 300w, https:\/\/www.dailynk.com\/english\/wp-content\/uploads\/sites\/2\/2020\/12\/\ucc38\ub9e4_\ud654\uba74-696x464.jpg 696w, https:\/\/www.dailynk.com\/english\/wp-content\/uploads\/sites\/2\/2020\/12\/\ucc38\ub9e4_\ud654\uba74-630x420.jpg 630w, https:\/\/www.dailynk.com\/english\/wp-content\/uploads\/sites\/2\/2020\/12\/\ucc38\ub9e4_\ud654\uba74.jpg 741w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-47112\" class=\"wp-caption-text\">A screenshot of the program. \/ Image: ESTsecurity Security Response Center<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">According to experts, North Korean smartphones have an independent authentication system along with a \u201cstate authentication\u201d system. The independent one authenticates files generated on the smartphone, while the state one gives North Korean authorities the ultimate power to grant authentication to particular files.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It appears that Chammae grants the smartphone\u2019s independent authentication to files.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In fact, a file authenticated using the IMEI of smartphone A was automatically deleted on smartphone B, while a file authenticated using smartphone B\u2019s IMEI was deleted on smartphone A. If Chammae had granted state authentication, the file would have run normally on both smartphones.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Additionally, the program has a separately defined &#8220;period of use.&#8221; This appears aimed at using regular program updates to minimize information spreading through smartphones.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The period of use of the copy of Chammae 1.0 obtained by Daily NK was Jan. 1, 2015 to Dec. 31 of this year.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cSince there is a period of use, it may not run normally on North Korea\u2019s latest smartphones,\u201d said Moon. \u201cWe have to test it on various smartphones to see if it runs properly.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Meanwhile, some observers raise the possibility that Chammae was officially created and distributed by the North Korean authorities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The national bird, the chammae (goshawk), has so much symbolic significance in North Korea that it is the codename of North Korean leader Kim Jong Un\u2019s official aircraft. Because of this, it would be somewhat difficult to stick the name Chammae onto a privately created piece of illegal software. The program\u2019s limited use period and need for continuous maintenance like updates lends strength to this claim. <\/span><span style=\"font-weight: 400;\">Moreover, if Chammae is an official program, Bidulgi would likely be as well. <\/span><\/p>\n<div class=\"td-post-header\"><em>Please direct any comments or questions about this article to dailynkenglish@uni-media.net.<\/em><\/div>\n<div><\/div>\n<div class=\"td-post-header\"><em><a href=\"https:\/\/www.dailynk.com\/%e5%8c%97-%ec%8a%a4%eb%a7%88%ed%8a%b8%ed%8f%b0-%ec%9a%b0%ed%9a%8c%ed%94%84%eb%a1%9c%ea%b7%b8%eb%9e%a8-%ec%b0%b8%eb%a7%a4-%ec%9e%85%ec%88%98-%eb%b9%84%eb%91%98\/\">Read in Korean<\/a><\/em><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Daily NK has obtained a copy of \u201cChammae 1.0,\u201d a program that can bypass the smartphone security authentications recently put into place by North Korean authorities on the country&#8217;s smartphones.
