Unzip the challenge (pass: cyberdefenders.org) and use your analysis tools to examine provided PCAPs and log files.
- You as a soc analyst belong to a company specializing in hosting web applications through KVM-based Virtual Machines. Over the weekend, one VM went down, and the site administrators fear this might be the result of malicious activity. They extracted a few logs from the environment in hopes that you might be able to determine what happened.
This challenge is a combination of several entry to intermediate-level tasks of increasing difficulty focusing on authentication, information hiding, and cryptography. Participants will benefit from entry-level knowledge in these fields, as well as knowledge of general Linux operations, kernel modules, a scripting language, and reverse engineering. Not everything may be as it seems. Innocuous files may turn out to be malicious so take precautions when dealing with any files from this challenge.
