With our <strong>CTF Advent calendar<\/strong>, we created a unique internal event that combined IT security skills with a Christmassy atmosphere. <strong>From December 1 to 24,<\/strong> our employees puzzled over new challenges every day and were inspired by humorous, festive stories.  <\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"A_special_kind_of_advent_calendar\"><\/span><strong>A special kind of advent calendar<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">CTF, short for &#8220;Capture the Flag&#8221;, is a popular format in IT security that involves solving tricky puzzles and finding digital &#8220;flags&#8221;. Our Advent calendar contained <strong>24 mini-challenges<\/strong>, which were unlocked at 9 a.m. every morning &#8211; plus an <strong>introductory task<\/strong> to make it easier to get started. <\/p>\n\n<p class=\"wp-block-paragraph\">The focus was on short, <strong>2- to 10-minute tasks<\/strong> that were specifically tailored to <strong>Linux tools<\/strong> and their use. Each task was accompanied by a <strong>humorous, Christmassy story<\/strong> that not only entertained, but also put the tasks into a festive context. A special highlight: the Advent calendar was displayed directly in the terminal and brought an extra dose of Christmas spirit with a virtual Advent wreath display &#8211; in which an additional candle was &#8220;lit&#8221; on each Advent Sunday.  <\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Great_commitment_and_positive_feedback\"><\/span><strong>Great commitment and positive feedback<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">The response was overwhelming: <strong>22 employees<\/strong> took part in the event and the feedback was consistently positive &#8211; even from colleagues who had little previous experience with CTFs. Many reported that they learned new tools and methods through the challenges and can now use them more confidently. <\/p>\n\n<p class=\"wp-block-paragraph\">The dynamic among the participants was particularly exciting. Some were so motivated that they jumped straight into the new tasks at <strong>9 a.m.<\/strong> to solve the challenges as quickly as possible. This commitment was also reflected in the results: The first places were fiercely contested!  <\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_winners\"><\/span><strong>The winners<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">In the end, <strong>Nils<\/strong>, <strong>Fritz<\/strong> and <strong>Lukas<\/strong> came out on top &#8211; their impressive performance was rewarded with small surprises that were sent to them. Congratulations to the winners! <\/p>\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion_A_successful_mix_of_learning_and_festive_joy\"><\/span><strong>Conclusion: A successful mix of learning and festive joy<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n<p class=\"wp-block-paragraph\">The CTF Advent calendar was not only an entertaining event, but also a valuable learning opportunity. With short, practical tasks, participants were able to expand their knowledge while getting in the mood for the festive season. <\/p>\n\n<p class=\"wp-block-paragraph\">A big thank you to everyone who took part and to the organizer, who created a special atmosphere with creative ideas and a festive design. We are already looking forward to next year &#8211; because one thing is certain: the SECUINFRA CTF Advent calendar will soon become a tradition! <\/p>\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1600\" height=\"1200\" data-id=\"56467\" src=\"https:\/\/www.secuinfra.com\/wp-content\/uploads\/\/IMG_2850-1600x1200.jpg\" alt=\"\" class=\"wp-image-56467\" srcset=\"https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2850-1600x1200.jpg 1600w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2850-800x600.jpg 800w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2850-768x576.jpg 768w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2850-1536x1152.jpg 1536w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2850-2048x1536.jpg 2048w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1600\" height=\"1200\" data-id=\"56464\" src=\"https:\/\/www.secuinfra.com\/wp-content\/uploads\/\/IMG_2849-1600x1200.jpg\" alt=\"\" class=\"wp-image-56464\" srcset=\"https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2849-1600x1200.jpg 1600w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2849-800x600.jpg 800w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2849-768x576.jpg 768w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2849-1536x1152.jpg 1536w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2849-2048x1536.jpg 2048w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1600\" height=\"1200\" data-id=\"56465\" src=\"https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2851-1600x1200.jpg\" alt=\"\" class=\"wp-image-56465\" srcset=\"https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2851-1600x1200.jpg 1600w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2851-800x600.jpg 800w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2851-768x576.jpg 768w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2851-1536x1152.jpg 1536w, https:\/\/www.secuinfra.com\/wp-content\/uploads\/IMG_2851-2048x1536.jpg 2048w\" sizes=\"(max-width: 1600px) 100vw, 1600px\" \/><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p>This year, the pre-Christmas period at SECUINFRA was all about cyber defense and festive cheer.
