Hey everyone! I've been trying to learn more about how EDR solutions actually work under the hood, and I thought the best way would be to see one in action. Since my team is evaluating Cybereason, I decided to run a super basic simulated attack on my test machine to see what it would catch.
I used Atomic Red Team, which has these little test "atomics" that mimic real attacker techniques. I picked a simple one, T1059.001, which is just using PowerShell to download and execute a mock "malware" (calc.exe in this case, nothing real!). I ran the command and honestly, I was kinda nervous even though it was a safe test lab.
The cool part was watching the Cybereason console light up almost instantly. It flagged the process as "Malicious" and showed me the whole command line, the parent process chain, and even tagged it with the MITRE technique ID. It felt like watching a really detailed data pipeline, but for security events! I'm still learning the interface, but seeing the timeline of the detection and all the context was super helpful.
For those of you who've used it longer: is this level of detail typical for all their alerts? I'm curious how the data is structured behind the scenes – like, is there a way to query these event logs similar to how you'd query BigQuery logs? I'm used to building data pipelines, so understanding the "data model" of the security events helps me grasp it better. Also, any tips on what other atomic tests are good to try for a beginner without breaking my lab? 😅
