[QUOTE="NoVirusThanks, post: 1013184, member: 68429"] [USER=65229]@BryanB[/USER] Checked the article and tried to reproduce the same scenario (K-1 06.13.2022.lnk on Downloads folder that executes the specified powershell encoded command). LNK File Guard blocked the execution of the .lnk file: [ATTACH type="full" width="989px" alt="lnk-test.png"]271032[/ATTACH] Then I disabled LNK File Guard and tried to run it, OSA blocked the execution of powershell: [ATTACH type="full" width="988px" alt="osa-test.png"]271033[/ATTACH] Additionally, firewall rules of SysHardener would have blocked regsvr32.exe from downloading the remote payloads.
