Endpoint System Logs: Cryptominer Analysis

In this lab, you’ll investigate a host that’s exhibiting signs of being compromised by a Cryptominer. As this lab focuses on a real-world scenario, the Indicators of Compromise (IoCs) that you’ll uncover will be heavily related to a threat actor named Rocke. You’ll investigate a Rocke-like campaign by diving into the Linux Auditing System’s logs. Even better, you’ll learn how to easily parse these logs through osquery!
