Full changelog

Anti-Virus False Positives

Warning: You will get false positives from certain anti-virus programs like Windows Defender and Web Browsers saying they have detected malicious files. They are detecting on Sigma .yml files that are not executable and just contain certain signatures from malware. They are not malicious. If you are running Hayabusa for live analysis and do not want to cause any anti-virus alerts, be sure to use the live response packages that use encoded Sigma rules.
