We first check the images type and when mount it within our system: When you manage to find and list them within your solution, this will be used a tiebreake Your task is to analyze the backup and to find additional information about its origin and evidence for potential cyber crime cases.ĭuring your analysis, you have to solve several small challenges were each solved challenge is rewarded with a flag of the following format:Īdditionally some configurations within the backup file indicate a threat to the OPSEC.

Now the police department seeks professional help from cyber security experts to further analyze the backup. Internal analysis found neither hints about its origin nor evidence for involvement in illegal activities. While investigating various cyber crime cases, the investigators managed to get hold of a suspects backup containing the entire homeĭirectory of a foreign system. If you are curious to know what a Hacker Contest Challenge looks like, or which flags you might have missed this time: This is our sample solution for the summer semester Hacker Contest Challenge. In the popular course, students get real insights into IT security and gain hands-on experience with tools and methods to search for vulnerabilities in networks and systems within our PentestLab.Īs every semester, prospective participants took on the Hacker Contest Challenge to qualify for participation.
In the summer semester of 2022, our "Hacker Contest" will be held again at Darmstadt University (TU) and Darmstadt University of Applied Sciences (h_da).
