The thumbnails of the recruitment banners were replaced with Koyuki\u2019s 3D model, and the in-game caf\u00e9s featured crowds of multiple Koyukis visiting simultaneously (this was later replaced with several versions of other students and Hatsune Miku). Additionally, the title of the game\u2019s information page was modified to &#8220;nihahaha,\u201d reflecting Koyuki\u2019s penchant for mischief. After an <a href=\"https:\/\/x.com\/EN_BlueArchive\/status\/1962147974253048174\" target=\"_blank\" rel=\"noreferrer noopener\">emergency maintenance period<\/a> that lasted roughly six hours, the abnormalities were corrected, and a formal investigation was conducted.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">Why did Blue Archive decide to bug out in the funnest way possible?

Based on the nature of the breach (which some players are now calling a \u201cKoyukification\u201d of the game), it seems that the perpetrator is also a fan of Blue Archive.\u00a0<\/p>\n\n\n\n<p>An investigation into the status of the global servers revealed that, other than the aforementioned abnormalities, no other data was tampered with or stolen. This includes sensitive information such as player accounts, game data, and payment information \u2013 all of which are stored in a separate database and routinely validated by the game server.&nbsp;<\/p>\n\n\n\n<p>Nexon has since implemented additional countermeasures that further restrict access to the internal workings of the Blue Archive servers.
