In the past few weeks, I have been using Gemma4 as a Large Language Model (LLM) to see how useful it can be to analyze some of the malware hashes uploaded to the DShield sensor over the past 30 days and figure out how its recommendation can be considered useful about the activity my DShield sensor is collecting and tracking. The model I use for this testing is gemma4:e4b [2] using two sites to compare the data against VirusTotal and CyberGordon.

Atuin does a great job of better organizing what is usually handled by "bash_history" and collecting meaningful additional data. Our reader David commented that this can also be done quite well with Linux's kernel process accounting feature, and I think he is very right.
