Decode the layers
Suspicious strings in logs and emails are often hidden under layers of encoding. Build a recipe of decoding steps to peel each one back to its flag, the way analysts do when they investigate. Every step runs right here in your browser.
Practice for defenders. This lab trains the skills SOC analysts, incident responders and sysadmins use to protect systems. Everything runs in your browser. The companies, people, data and IP addresses are made up, and nothing here touches a real system. Only use security skills on systems you own or have written permission to test.
