Many people use @sigma_hq rules. That's great. We like to share detection knowledge. Don't be afraid to contribute in 2025. Even a simple False Positive is good. If your boss don't want just ask until having an yes 😝

This is a really interesting web page published in the @Virustotal UI that lists the applied @sigma_hq rules on samples executed in their sandboxes and on how many of those samples the particular Sigma rule matched but not a single AV engine virustotal.com/ui/sigma_rules
